#skimming asks

Historic records mentioned studies of the volcanic activity on the island more than a decade ago. Mines had also been dug out in the cave systems throughout the island long before Sonic had been born, in search of potential esoteric energy sources.

The Chaos Emeralds, no doubt.

But other than that, it seemed the island had never been properly settled. Sonic could’ve flown over in the Tornado for a quick jaunt—running to small islands never boded well for him, they were always tricky to aim for—but he knew it wouldn’t have the answers he was itching to find out.

And sure, the big one was already answered. The sick baby fox he’d had to leave behind in the care of some flickies after that rainy night obviously made a full recovery, or else Tails wouldn’t be alive in Sonic’s present, off on his own adventure. Flying solo. Alone.

But knowing that without actually seeing it, experiencing it for himself, didn’t satisfy Sonic in the slightest. He was all about experiences. And he wanted to experience this mysterious chapter of his best bud’s life, one he never really let himself think all that hard on.

So, that was how Sonic found himself on a nearly deserted island eight years in the past with two Chaos Emeralds in hand. It was warmer than in his present, willing to bet they were somewhere in spring or early summer as opposed to late fall, but the dense cover of pine trees kept the forest floor cool in its shade. Allergies tickled his nose, prompting Sonic to scratch at it as he took in his surroundings. Flickies sang throughout the branches, their chirps a comforting song accompanied by the steady hum of insects hidden in the brush. With his own curious hum, Sonic picked a direction and ran with it—er, walked with it. He took it slow for the moment, trying to find his way back to the cabin from that night. It seemed like his best bet to start his search for Tails.

Until a child’s voice somewhere in the forest caught his ear, both perking up and flicking towards the sound with an instinctive pull as everything else faded into the background. A breath Sonic hadn’t realized he’d been holding lifted from his chest. The child sounded light, healthy. No coughing or crying as far as he could tell. 

Sonic followed the voice to a clearing. Unlike the stormy day he’d first stumbled in on, sunlight flooded the patch of grass between the trees with its warm beams. One fell across a tree stump where a two-tailed fox kit lay sprawled across on his tummy, bright-eyed and bushy tails further confirmation that he’d made a full recovery. Sonic’s shoulders sagged with relief as he observed him from the brush, his own green eyes lighting up as he realized he was playing. Making motor sounds with his mouth, Tails rolled a toy airplane through the long, wild grass. His tongue poked out as he accidentally blew raspberries amidst his very serious airplane noises.

“Pfft—” Sonic’s laugh nearly sputtered out of him, cut off only by the fact that the kid heard him and froze.

Ears swiveled in his direction, but Tails couldn’t see him through the trees from his spot on the stump. The toy airplane fell to the grass with a soft thump as the baby fox squirmed and tried to hoist himself up into a sitting position, his two blue boots dangling just over the edge as his bare hands planted themselves on the wood between them to support himself. One tail flicked up and down with excitement while the other twitched limply against the tree stump, like it didn’t know it could lift itself up like its twin.

“Mom?” he called out, and the hope in his voice ensnared Sonic’s heart in a vice. “Mom!”

“Ah, sorry, little guy. Not mom.” Sonic stepped out from behind the brush with his hands up, a sheepish smile on his face. “Just me. Long time no see.”

His tails immediately wilted as the bright-eyed, eager expression on his face retracted into something shy and pensive. But not scared, Sonic noted. There wasn’t a trace of fear in his eyes.

“Remember me? I stayed with you during that rainstorm the other night,” Sonic added, hoping to jog the little guy’s memory, but he didn’t actually know how long it had been since that night. 

He didn’t have Silver’s neat little time travel gizmos. His comm couldn’t pinpoint where he was in time, only in space. Which meant he couldn’t stay long, because if Tails or anyone else tried to ping his location, it’d probably come up blank. 

The Tails sitting in front of him drew his legs up, curling into himself a bit the closer Sonic got. Okay, well maybe he was a little afraid. Sonic stopped short of reaching the tree stump, hoping a reassuring smile would get him the rest of the way.

“My name’s Sonic. Sonic the Hedgehog. What’s yours?”

Tails stared at him for a moment, until his gaze slowly slid past him to focus on the tree line behind him. Sonic planted his hands on his hips and canted his head back to see if anything was there, but aside from the buzz of insects and rustling of flickies in the leaves, the forest was still. No one else but the two of them smack dab in the middle of it.

“…Mom?” Tails whispered, grabbing onto one of his tails to hold.

Sonic’s smile slowly slid off his muzzle. In all the time he’d known Tails, he’d never once called for his mom. Not a single cry. By the time he came into Tails’s life, whatever innate trust he’d had for this faceless person had completely evaporated. There was only one person Tails had ever called out for, ever cried for, ever searched for when he was lost or scared or lonely.

Sonic swallowed thickly. “I don’t know where your mom is, bud. You waiting for her?” Tails nodded with the most intense certainty, his ears flopping forward and back with the force of it. “Did she… did she say when she’s coming back?” 

This time Tails pursed his mouth as he thought carefully about his answer, his pensive expression the same one he’d still make to this day when he debated how to explain something to him. If he should explain something to him. If he should give his big bro a glimpse into the inner workings of his big brain, or if it’d be easier—safer—to keep it all to himself.

And just where’d he pick up that particular trick?

But this Tails was young enough—hadn’t been hurt enough—to trust someone who looked like a grown-up, so he slowly shook his head in response, wide blue eyes gazing up at him like there’d be some sort of prize if he answered all the questions correctly. 

Sonic’s brow furrowed. “Do you know how long it’s been since you last saw her?”

“Long.” The small, squeaky voice was so matter-of-fact, Sonic nearly fell over with the sheer amount of joy a single syllable filled him with; his little bro’s attitude had been baked into him from the start.

“I’ll bet,” he huffed out a chuckle, choosing to sit cross-legged in the grass so he wasn’t towering over Tails like some kind of threat. “You like planes?” Sonic glanced meaningfully at the toy plane still discarded in the grass.

Tails glanced down at it, the tip of his tail in his mouth as he gently chewed on it. “Mmhm.”

Though Tails had long-outgrown the habit of chewing on his own tails, Sonic would still occasionally catch him nibbling on the ends of pens and pencils when he was deep in thought or starting to get hungry. Or, at least, he used to. Back before Sonic had been captured and Tails had been out on his own for six months…

“I like ‘em, too,” Sonic piped up with a grin. “Probably my favorite way to travel! Second to running, of course.”

Tails blinked at him, head canting to one side. Sonic’s smile grew and he scooched forward a couple inches, steadily closing the gap between them.

“Y’see, running’s sort of my thing. What kinda things do you like to do?”

Tails glanced down at the toy plane again, then up at the sky. He pointed shyly at the white, puffy clouds slowly floating by overhead. Sonic followed his gaze, unable to help the way his smile crooked to one side.

“You like to watch the clouds?” Sonic filled in for him, beaming when Tails nodded. “Me too. You ever look for shapes in ‘em?”

The little guy’s brow furrowed. “Shapes?”

Sonic laughed as the perplexed, and ultimately unconvinced, expression remained fixed on Tails’s face. “C’mere, I’ll show ya!”

Unceremoniously flopping onto his back, face turned towards the sky, Sonic patted the grass beside him. Though they were mostly shielded by the thick cover of trees, a light breeze still wafted down into the clearing and carried the salty scent of the sea with it. The stands of grass tickled Sonic’s side as he laid back and took a deep breath, listening for the familiar patter of eager footsteps following his lead.

Except they didn’t come.

Sonic pushed himself up onto his elbows. Tails was still curled up atop the tree stump, chewing on the tip of his tail as he watched him with worry in his eyes. Worry that had no place being there in a kid so young.

So Sonic cracked another smile. “Don’t worry. The floor’s not lava,” he teased, but it was something the toddler obviously didn’t understand. “It’s safe, bud. I’m not gonna hurt ya. Promise.”

Tails’s gaze darted to the treeline again, searching amongst their thick trunks and low-hanging branches before snapping back to Sonic. “Mm… s’pposed to wait here,” he mumbled, his words sounding a little thick as some of his syllables slurred together in a mouth that was still so small, but ultimately what he’d said was clear enough for Sonic to understand.

His smile slowly faded as he processed the simple explanation; the same feeling rising in the back of his throat as when he sat with a sick Tails in the cabin while the kid asked if he could go home. “Your mom tell ya that?”

Tails nodded. “Wait here. Be good.” His little face scrunched up in a look of pure, earnest determination. “Wait here an’ be good, then mom will come back. She said… she said.”

But she wouldn’t.

No one would.

And maybe Tails already knew that. Even if he didn’t want to believe that someone he loved would leave him, he’d always been a smart kid. Tails’s tiny claws caught in the fur of his tail as he clung tighter to it—like he could physically cling to the hope that his mom would still come back if he did this one thing really well.

If he did his very best.

“Look Sonic, I made this for you!”

“Sonic, I’ve made some adjustments to the Tornado’s aerodynamics, so her base speed has more than doubled! Pretty cool, huh?”

“I made a radar to help us track the Chaos Emeralds faster!”

“I still need to optimize your Extreme Gear’s turning radius and acceleration for your next race. It’s not good enough.”

“The Cyclone still has a ways to go in terms of balancing its different modes of transport. It’s just not good enough at land or air travel yet.”

“I’m wildly inconsistent. I’m just a burden to you. I’m not good enough.”

Not good enough.

Sonic’s fingers dug a little firmer into the soft, damp soil beneath the grass. “Well, I mean, ya gotta get off that stump sometimes. What about when you get hungry? You leave to go get food, dontcha?”

Tails stiffened, fur frizzed up like he’d been caught with his hand in the proverbial mint chocolate chip cookie jar. “Don’t tell,” he pleaded, eyes wide as panicked tears welled up. “I’m sorry—”

“Woah. Hey, hey, hey,” Sonic sat up straighter so he could lift his hands, using them to make a calming gesture as Tails’s little chest started to heave with each little gasp. “Easy there, bud. I’m not gonna tell her.”

“…Not?”

Despite the storm brewing just beneath the surface, faced with further confirmation that Tails had never truly felt safe or wanted, he refused to scare the kid with its intensity. Offering up a kind smile and reassurance, Sonic held up a finger to his mouth. Like they were keeping secrets from some nameless authority figure they’d never shared. 

“I won’t tell if you won’t.”

Tails’s ears perked up and the grip on his tail eased up. “M’kay…”

“M’kay,” Sonic mimicked, smile growing as he watched Tails scrub at his face with the fur of his forearm. “C’mere, kiddo. Watch the clouds with me.”

Tails looked at him for a moment, then scooted closer to the edge of the tree stump. He swung one leg over, then the other, his little boots scraping against the bark as he eased himself down. He was a little off-balance as he toddled over. Both arms splayed out to steady himself as one tail flicked up and the other was dragged behind him, still as limp and awkward as it had been on the stump.

Sonic’s gaze narrowed in on it immediately. “Didja hurt your tail?”

Tails paused and craned his neck back, wobbling a little as he tried to look behind him. “No,” he answered simply.

“Then how come it’s not up like your other one?”

Tails reached behind him and picked up the limp appendage, hugging it to his chest. “Doesn’t do it.”

Sonic’s frown deepened. “Let me see it.”

Tails didn’t even hesitate. He let go of his tail as he waddled right over to him. He turned his back to him, giving him complete access to the part of his body he protected the most. Sonic was the only one he’d learned to trust with them over the years, but he’d had to earn it. 

Sonic gently ran his fingers through the fur, watching his baby brother’s posture for any sign of discomfort. He didn’t flinch, but his good tail started wagging almost immediately, thwacking Sonic in the side of the face. 

“Careful with that,” he chuckled, catching it in a loose hold when it smacked him again. “You could take someone’s eye out with one of these bad boys. Here, hold onto this for me.”

He waited for Tails to grab onto his eager tail, hugging it hard when it wiggled uncontrollably. “S’tryna get away,” he giggled.

“Oh boy, better get a good grip. It’s a slippery one, that tail,” Sonic laughed, using the distraction to his advantage as he palpated along the base of the weaker tail with his fingertips.

There was barely any muscle to it, and the fur was patchy and matted, flattened in a way that his other tail clearly wasn’t, even though his fur overall could’ve used a good brushing. But it wasn’t injured, no welts or bruises or cuts. It was just… weak. Like it was developing slower than its twin. He’d caught a glimpse of it that night where he was sick, but now that he was getting a good look at it, the differences between the two were stark. He couldn’t imagine why; Sonic’s brain literally wouldn’t let him conceive of a situation where this would happen—where Tails wasn’t allowed to use one tail to the same extent as the other.

Whatever had caused this had reversed itself by the time Sonic met Tails, both little propellers of equal strength. At least, he thought they were. To be fair, he’d only been eleven and he hadn’t looked all that closely at them. And Tails barely let him patch him up from where he’d been smacked around by bullies or badniks in those first few weeks.

Idly petting along the length of his tail, Sonic stilled when it spasmed against his palm. Just looking at it, he’d have thought he accidentally pulled on it or snagged his fur, but there was a gentle rumbling sound emanating from Tails’s chest that assured him otherwise. Sonic flicked his gaze up to see Tails watching him, a smile on his face while he purred openly. His tail jerked in his hold again. It was trying to wag.

Sonic’s shoulders sagged, his own smile lopsided as he let his tail slip from his grasp. “All clear. Time to park those two tails of yours right here on the runway.”

Tails squeaked as Sonic nabbed him around the middle, but dissolved into a fit of giggles as he was lifted up and plopped down on the grass next to him. Kicking up one leg over the other, Sonic laid back once again, arms pillowed behind his head as he let out a contented sigh. Beside him, Tails laid back and wiggled a bit to get comfortable, both tails swept to the same side so they wouldn’t get pinched underneath him. He tilted his head up to look at the sky, the same color reflected back in his eyes.

“Shapes?” he asked.

“Yeah, we’re gonna look for shapes, little buddy,” Sonic hummed. “Go ahead and tell me what ya find.”

Tails considered the sky for a moment, then pointed at a blob above them. “Oval.”

A sharp laugh burst right out of Sonic. “Sorry, sorry,” he wheezed when Tails pouted at him. “Not those kinda shapes, pal. I’m talking things like flickies or flowers or chili dogs! But good first try. I’m thinking that one looks more like… a whale.”

“Whale?”

“Uh-huh. See the tail?” Sonic removed one hand from behind his head so he could trace the oblong cloud as it faintly curved upwards at the end, making sure Tails’s eyes followed where he pointed. “And there’s its fin. And the wispy bits at the top are like the water shooting out of its spout.”

“Spout,” Tails echoed, blinking up at it like he was trying to solve a puzzle. 

“Yeah, you know. Like when they come up from the water and all that mist sprays from that hole on top of their heads like…” A devious grin spread across Sonic’s face before he looped his arm around Tails and dragged him close enough to blow a raspberry against his cheek with a loud, “pbbbbbbfffft!”

Tails squealed, legs kicking as he squirmed about instinctively, but made no move to pull away entirely. The ticklish sensation buzzed through him like a bunch of tiny butterflies; the feeling silly, unfamiliar, and almost overwhelming all at once. He eventually pawed at Sonic’s muzzle, pushing it away from the fluffy, baby fur of his cheek, but he was smiling and laughing as he looked over at him, eyes shining with delight.

“Was that funny?” Sonic snickered.

“Yeah!” Tails beamed at him, his tails beating an inconsistent rhythm against the grass. “You’re funny.”

“I’m funny?” Sonic feigned offense. “Excuse me, but seems to me like you’re the funny one, wiggling around over here like a cup of sparkle gelatin!”

“No!” Tails squeaked, curling up when Sonic poked him in the tummy. 

“No?” Sonic eased back, reminding himself to reign it in a bit so he could figure out if the “no” was just in play or if he was serious. 

As much as he wanted to give this little guy something to smile and laugh about while he was out here on his own—and it was so easy, it was almost intoxicating when he hadn’t seen his brother’s smile in weeks—he didn’t want to overwhelm the kid. But as he let him go and pulled back, a panicked look flashed in Tails’s eyes. His smile fell and a fear that was too big for a guy so small replaced it as he froze up.

“Hey, it’s okay. You’re okay.” Sonic lowered his voice, but even that didn’t stop the tears from suddenly sprouting in the corners of his eyes. “Was that too much? Sorry, kiddo. Not really used to you like this. I don’t know your limits.”

Tails didn’t answer him, probably because he didn’t know how. He was a baby, after all. Four-year-old Tails had often had trouble expressing how he felt or what he wanted. And heck, even ten-year-old Tails was still facing that particular issue. He couldn’t expect a maybe-two-year-old to know…

Tails’s tiny paw reached for Sonic’s arm, the light touch barely registering as anything other than an itch before his fingers curled into his fur. Sonic stared at his hand for a second, then immediately darted to his face. Tails sniffed, muzzle quivering as he held back his tears.

Always sucking it up. Always putting on a brave face. Always trying to be a big kid, like his big bro.

Even when he was just a baby.

“It’s okay,” Sonic repeated, his arm curling around Tails again. “I’m right here, it’s okay.”

Tails nestled against his side, nuzzling his face against him with a shiver and a barely suppressed whimper. “Mom… dad…”

The storm returned with a white-hot flash of frustration and resentment. Sonic directed his glare at the cloud whale lazily floating past them, since he couldn’t look the people responsible for this in the eyes. Not that he particularly wanted to. If they never crossed paths, his and Tails lives would only continue on for the better. That was one thing he was still certain of. There was nothing in the universe that could convince him otherwise.

Not even the baby who desperately wanted them.

But he didn’t know any better. They were all he knew. 

Releasing a long sigh, Sonic let go of the past and pulled himself back into the present—or, well, two-year-old Tails’s present anyway. He patted Tails’s side, then ruffled his fur a bit when he cuddled closer. His fur tickled as he rubbed his little face against his ribs, so Sonic scooched him up a bit more until his cheek was pillowed against his shoulder.

“Sorry if I scared you, bud,” he hummed, watching as one of Tails’s ears twitched from the lull of his voice. “Didn’t mean to. You’re safe with me, okay? When I’m around, I’m always gonna do whatever it takes to keep you safe.”

Tails tipped his head back to watch him, silently absorbing his words, even if he didn’t understand them. But as Sonic looked down at him, he saw his four-year-old brother snuggling up to him in a storm and his six-year-old brother falling asleep on him during a movie and his eight-year-old brother trying to be strong for Sonic as they lost another friend… He could see all of Tails in the way he looked at him, every moment where he let Sonic see a little of that vulnerability he always tried so hard to hide.

He could even see his ten-year-old brother, hundreds of miles away, determined to bury that vulnerable little kid for good, somewhere Sonic would never find him. And that was fine. If that was what Tails wanted, then Sonic wanted that for him. He wanted Tails to feel confident and capable and every bit the hero Sonic saw in him every day.

“And even when I’m not here… when you can’t see me? I’ll still be with you. Wherever you go, whatever you face, you won’t have to do it alone.”

Tails sniffed, then lifted his head to gaze up at him. “Pomise?”

Sonic’s breath hitched, his eyes as wide as saucers as the fox kit who’d only known him for a few minutes at most looked at him with nothing but trust. “Yeah. I promise.” He had to clear his throat, then tugged Tails up to sit on his chest. “You’ve got no idea just how stuck with me you are, keed.”

“No idea,” Tails repeated, shaking his head with the utmost seriousness a two-year-old could express.

Sonic’s laughter traveled through him and right up into Tails, the two of them shaking with it. The feeling of being bounced about coaxed a few giggles out of Tails and he nearly slid off his unsteady perch. But Sonic’s hands supported him, holding tight so he wouldn’t fall.

“You’re the best thing that’s ever happened to me,” Sonic choked out as his laughter petered out on a breathless sigh. “Don’t ever forget that, okay?”

“M’kay,” Tails agreed.

“M’kay.” With one hand remaining on Tails’s waist, Sonic lifted the other to poke him on the tip of his nose, grinning at the way he went cross-eyed from following his finger. “I’m gonna follow up on that in eight years, y’know, so better work on committing that to memory, stat.”

“M’kay.”

“I mean it. There’ll be a test and everything.”

“M’kay.”

“You’re so agreeable,” Sonic sighed, closing his eyes as he laid his head back, leaving the comfortable weight of the baby fox on his abdomen. “I don’t think I know what to do with a little bro that actually listens to me.”

He felt Tails squirm a bit, one knee digging into his ribs as he attempted to scoot further up, then a finger lightly tapped Sonic on the tip of his nose. One green eye cracked open, immediately greeted with a pair of pleased blue ones and a wagging fox tail. Despite the fact that it was pinned beneath him, pressed into the grass, Sonic felt his tail give a jerky little wag, too.

“Shapes?” Tails asked.

“You wanna look for more shapes in the clouds?” Sonic waited for Tails’s eager nod before turning him around and laying him back in the grass beside him. “You got it, bud! You need a redemption round, after all. Let’s see what kinda shapes you can find this time.”

Tails hummed, contemplative gaze fixed on the clouds for a good minute before he pointed slightly to his left. “Floor!”

“Floor?” Sonic squinted up at the cloud, making sure he was looking at the right one. “Oh, ‘flower!’ Yeah, that does kinda look like a tulip flower. Good eye, kiddo.”

Tails nodded proudly. “Mmhm. Floor.”

“Flower,” Sonic repeated, and even made the sign for it, touching each side of his nose with his fingertips, like he was smelling a flower.

“Floor-er.”

“Close enough,” he chuckled. “Oh, okay, now that one looks like a crab claw. Like from a crabmeat.” Grinning devilishly, Sonic made a claw-like grabby motion at Tails with his hand while the little guy laughed. “Or, y’know, an actual crab.”

They watched the clouds, picking more shapes out of them until Tails’s stomach started growling. Sonic quickly sped through the forest to gather up whatever kind of fruits or vegetables were available on the island, eventually settling on some peaches, plums, and cherries. He grabbed them from the other side of the island, so as not to take from anywhere Tails was likely to forage on his own. He liked the plums and peaches, the sticky juice staining his muzzle as it dripped from his hands. He kept trying to lick his fingers clean while Sonic wiped the fur around his mouth so it wouldn’t bother him later when it dried. He didn’t care for the cherries as much, but Sonic still left a small stash of them and the leftover peaches at the base of the tree stump.

With a full tummy and sticky paws, Tails let out a big, squeaky yawn before he curled up on top of the tree stump. His tails covered him like a blanket as he settled down for a nap, giving Sonic just the out he needed. He’d been debating how to head back to his present time without sounding any alarms for Tails. He honestly wasn’t sure he’d be able to if the kid just looked at him with those sad eyes, like he was being abandoned all over again.

But if Tails was asleep, then maybe this would all have felt like just a dream. Sonic had just wanted to check on him after leaving him so abruptly that first time, and then he figured it couldn’t hurt to give him one good afternoon. There would be so many days where he’d be on his own after this, so many months before their paths would cross. One afternoon where a stranger showed him kindness and played with him wasn’t going to break the time stream, but even Sonic knew it couldn’t really go further than that.

“I’d break time lines for that kid.” His own words echoed at the back of his mind, the certainty he’d felt at the time faltering when faced with the sleepy face of a baby fox who wasn’t supposed to have met him yet. It wasn’t so simple.

Sonic waited until Tails’s breaths were deep and steady, arms wrapped around the weaker tail while the stronger one blanketed him with its fluff. Smoothing down his bangs with his thumb, Sonic gently stroked the top of his head and scritched behind his ear.

“Love ya, little bro,” he whispered.

Things would be okay, Sonic reminded himself as he backed out of the clearing, picking up the two emeralds that were his ticket back to his time. Because they were okay in the present. Even if Tails wouldn’t be there when he returned, they would still be okay. Eventually. They always came out on top. Sonic still believed that.

If there was anything he still believed in above all else, it was Tails.

So, to be fair, when he left the Poloy Forest that afternoon, it had been with the intention that this wouldn’t happen again.

But then, Sonic the Hedgehog’s impulse control wasn’t his claim to fame, was it?

---

A/N: Anyway, just wanted to say thank you again, 0vergrown, and that I appreciate you so much! I'm so happy you're interested in this little side plot I've got brewing and all the angst potential that it holds <3 I have so many little scenes I want to write for them, you have no idea! Hope this scratches a bit of the itch for more of these boys who need so much therapy. So much...

Structure and Pacing

For multi-chapters, I like to sprinkle the fluff throughout so I'm not overloading the reader with a sugar rush. I try to have some kind of sweet, light moment every four or five scenes to stay invested and hooked on why the relationships between characters are so important.

Character is the driving force behind a lot of my writing, they inform the plot and it adapts around them. Giving the characters these spaced out fluffy scenes also gives the readers a chance to breathe and soak everything in. Like a pit stop while running a marathon to grab some water or a snack to recharge!

For a one shot, I can get away with the fluff being more concentrated; go all in on the specific feeling I want to evoke (comfort, contentment, laughter, security, unconditional love, etc.) If it feels like too much to the point that it's sickly sweet, I can always shave off some of the fluff and make it more palatable, but going big in a one shot at least gives me a goal to aim for and lets me know what I personally want out of a fic.

Author's Intent

And what you want out of a fluff fic is also an important piece to consider. Fluff is self-indulgent by nature. It's something you wish you could see if time limits, budgets, and marketability played no part in the show/game/media that you love. When the writer is genuinely invested in what they're writing, that feeling also reaches the reader and makes it matter to them, too!

Characterization and Emotional Layers

If you're concerned about your fluff feeling believable or in character, establish a baseline for character interactions in their downtime, with low stakes. In the case for Sonic and Tails, I can see this as traveling for fun or trashing an Eggman base. Figure out how comfortable and familiar they are with each other normally, then build on that.

So let's take an example of Sonic and Tails sharing a victory together after taking down a surprise boss in an Eggman base.

Baseline: Sonic and Tails fist bump each other. It comes naturally, second nature, easy and they don't think too hard on it.

1st fluff layer: Sonic musses up the fur on Tails's head or slings an arm around his shoulder. Also comes naturally, but it's highlighting how comfortable they are with each other. There's usually a secondary emotion involved with these gestures (Sonic might be feeling proud, playful, or trying to subtly de-escalate any stress or worries Tails might be feeling. Tails's reaction to this also makes a difference - does he bat him away playfully to keep the air between them light and fun? Or does he lean into the touch because he needs the reassurance or because Sonic needs the reassurance?)

2nd fluff layer: Tails flies at Sonic and is scooped up/tossed in the air/swung around for a victory pose. Excitement at its peak for them both, they can't contain it. They instinctively reach for each other because they want to share their joy with each other. Tails riding the high of his success or accomplishment and immediately seeking out Sonic, while Sonic is just as eager to support and cheer his little buddy on. He always believes in him, but seeing Tails believe in himself is such a treat.

Building on existing canon dynamics like this can keep characters still feeling like themselves even if they're behaving in a way we haven't actually seen much evidence for. Like, Sonic is frequently pictured with guitars so we can assume he knows how to play. We don't know whether or not he would play the guitar to comfort Tails in a storm or after a nightmare, but it's not necessarily a stretch to imagine that.

Now, this is just if getting characters to feel like canon depictions matters to you as a writer. I personally straddle the line: I look to canon for guidance, but ultimately I've spent 30 years with my own ideas for these characters marinating in my head, so at the end of the day I'm probably just going to do what feels right to me. Don't let canon become restrictive to the point that it chokes all the creativity out of you. Use it to fuel your inspiration!

All this being said, when it comes to fluff, the most important piece of all is "does it make you, the writer, happy?" If it makes your heart flutter and you have to stop writing mid-sentence to press your hands over your face and groan, "I just can't with these two!" then you're on the right track!

Initially I thought Zooble gravitated towards quality time as their main way of showing love, since they're the one to suggest drawing with Gangle as a way to spend more time with her and purposefully seek her out to make sure she isn't alone at the end of episode 4, despite coming across as someone who prefers to be on their own in the first couple of episodes. But starting in episode 6, they pretty much find a way to initiate touch with Gangle in every episode going forward, especially in episodes 8 and 9 where they just leave their hand on her shoulder for extended periods of time, which made me rethink their preferred approach to expressing and receiving love.

I think Zooble is most comfortable expressing love by initiating physical touch. They want their presence and support to be felt by the person they love, so they naturally reach out and use their body to show and provide that reassurance. I think it's also a way for them to try liking their body a bit more too. If it can be used for something good, like showing love and affection and giving pleasure, then maybe they won't hate it so much.

I like to think they start taking the initiative in episode 6 to start initiating casual touches with Gangle because she trusted them with her comedy mask first, solidifying how close the two of them have become and giving Zooble permission to reciprocate. But while touch is how they might show their love, it's not always how they prefer to receive love, and honestly it's probably for the same reason. They don't like their body, they don't feel connected to it. If it's being touched outside of their control, it makes them aware of it in a way they're not always ready for. They definitely don't like being touched casually by most people and can get kind of cagey and distant when their partner is the one initiating touch if they're not in the right headspace for it. I think it is the biggest display of trust for them to let someone touch them first, so they need time to build up to that.

A more successful way of showing Zooble love initially would be through quality time. I think being in the presence of the person they love helps regulate them. If they're in an awful mood, just sitting next to Gangle on the couch and watching her draw relaxes them. Just knowing that they're allowed to take up space without doing or saying anything and that there's a place for them with her is enough to soothe them and get them to open up a bit more. Pushing with Zooble doesn't work, they'll just pull away and put up walls. But just sitting with them first, accepting them as they are, is how they feel safe enough to open up and accept other displays of love.

I like to imagine, post-finale, when they're seeking affection, they'll start by lying next to Gangle while she draws, eventually laying their head in her lap to receive head scratches or other grounding touches to help them feel centered in themself. They'll also gravitate towards being the little spoon, letting Gangle wrap herself around them so they can feel her touch all over. They say it's for her at first, since she's used to sleeping with body pillows, but it's also because they really, really like being cuddled and wrapped up in her.

Now Gangle on the other hand... I think she has more of an anxious attachment style, where she needs clear reassurance that her partner doesn't secretly want to abandon her for something better. She looks down on herself so much and gets stuck in this negative perception of herself that I think words of affirmation are what help her. Being told that she's loved and accepted and wanted replaces the negative self-talk in her head and gives her something to cling to.

Zooble ends up getting really good at giving pep talks because Gangle needs to hear the words as well as feel their presence physically. She'll never say no to cuddling, of course - she loves cuddling with Zooble - but it helps to hear verbally that she has permission to act on what she wants. The tone of voice matters, too, so Zooble softening their words for her goes a long way to making her feel safe and loved.

But she's not as good at speaking up, so she often resorts to showing her love rather than speaking it into existence. She gives gifts in the form of her art, and quality time is also a way of her showing that she trusts someone to share in her interests. If she's sharing her favorite anime with someone, risking their opinion on something she holds dear and whether or not it will affect the way her partner sees her, that's a true display of trust and love. If she's letting Zooble watch her draw, she feels safe enough that she doesn't have to perform for them. It's opening up to show parts of herself unguarded, unmasked, without fear of judgment.

Once she's more regulated and secure in her relationship with Zooble, though, she's able to freely speak her words of affirmation, too. She tells them how they've made a mark on her life, how much they mean to her, how beautiful they are, how handsome, how they're everything she could ever want. Words might not affect Zooble in the same way, but they know how important they are to Gangle and that she wouldn't say things if she didn't mean them. And they still deserve to hear them. So she loves showering them with compliments and assurances that they're enough for her, just as they are.

But yeah, those are some of my thoughts on how they tend to show and receive love from one another! I think there are a lot of ways to interpret how they express their love though - like, you could also make the argument that touch is Gangle's preferred love language, so Zooble going out of their way to touch her is for her sake and that their preferred love language is acts of service. And again, the love languages aren't rigid labels that people get locked into, they're more of a vocabulary tool to help people find the words to express what they need from their partner and to also help them pay attention to how they actually react to/initiate affection.
