Super Sonic's brow furrowed as a barrage of bullets opened up on him. He weaved between the hundreds of projectiles glinting dangerously in the sunlight, but his chaos energy and speed worked in tandem, as fluidly as a dance, while he searched for another opening to try the cyloop again.

He could beat this thing without it, sure, but it was the fastest way to take it down.

"Tails? Still with me, bud?" Super or not, Sonic still spared a second to check in, static ringing in his ears as he burst through the center of the mech's chest plate for a shortcut.

"I'm here," Tails answered, but his voice sounded faint, like the feedback was drowning him out. "Sorry, I…" Super Sonic started his cyloop. "I just wanted to—" He was halfway around. "I'm sorry—"

Sonic closed the loop. A burst of chaos energy swelled up with a deafening boom. The air rippled with the force of it in great gusts of wind that rocked the trees and the grass of the nearby hills. Waves rose up in the bay, their white caps scraping the bottom of the golden bridge that marked the edge of the sea. The fake titan lifted into the air, sparks crackling off its metal casing as its system overloaded. Super Sonic didn't give it a second to recalibrate itself.

Faster than anyone could see, he smashed into it on all sides. A tiny mote of golden light against the towering behemoth, but it struck every weak point, fried every circuit, as the chaos energy pressed in on it from the outside. Metal crunched and caved it on itself, contorting into a twisted configuration until it no longer resembled a machine.

A cheap imitation of the ancients' attempts to defend themselves, designed only to destroy instead of protect.

Super Sonic grabbed onto mech's arm—or maybe its leg, it was hard to tell at this point—as the cyloop's effect faded, catching it before it crushed Westopolis. He swung it around and around, gritting his teeth as he built up momentum and set his sights on the ocean out ahead of them. Whoosh, whoosh, whoosh—

Super Sonic let go.

The mech's remains were flung through the air, over the coastline and beyond the bridge that cut off the bay from the sea. It crashed into the water, the ocean spray shooting up into the air in a tower of mist once it hit the surface. The waves rolled aggressively towards the coastline, but ultimately broke apart in the bay before they could do too much damage. Some millionaires might have to replace a yacht or two, but that wasn't Sonic's problem.

As he dusted his hands off, he could finally acknowledge the warning bells Tails's last words to him had set off. "Hey, what was that, bud? I didn't catch—"

Super Sonic turned towards the satellite, addressing it like he would Tails, but it was gone. Instead a cloud of smoke filled the space where the satellite had been not ten seconds ago. Metal shards and fire rained upon the bay. Everything in pieces. Everything gone.

His comm was in chaos. Unintelligible voices shouted over one another in a cacophony of white noise that was already fighting a losing battle to the ringing in his ears. But he still noticed one voice was missing. He couldn't hear it.

He hadn't heard any of it.

Over the sonic boom of his cyloop and the screeching of metal as he demolished the titan, Sonic hadn't heard the satellite explode.

The satellite his little brother was on.

He'd been trying to tell him something.

He'd been trying to tell him something before a satellite exploded with him on it.

"I'm sorry."

Tails. 

Super Sonic shot off like a bullet, speeding towards the black cloud of smoke and smoldering debris like there was even a chance—

No. There had to be a chance—

"I just wanted to—I'm sorry—"

Why? What happened? What did you do, Tails?

He hadn't even properly seen him off before he left. Tails had been trying to hack into Eggman's satellite remotely while Sonic was out chasing after the faux titans. He told them all about his plan to board the satellite and everyone agreed it sounded like the right call, so long as he could do it quickly. They needed to disrupt the signal, after all, and Tails was their best shot.

That was what he'd said, wasn't it? "You're our best shot, Tails. I believe in you, partner."

Their best shot, but not the only one. Not if it meant this.

Nothing was worth this.

Sonic didn't need to breathe while super, but his lungs still burned twin holes in his chest as his own nervous system caught fire. Golden sparks flicked off his quills as he raced through the air. Fiery eyes frantically scanned each scrap of metal that fell, but they must've already been irritated from the smoke because they burned and blurred with the rest of the world around him—

"—onic, wait! Come back! Sonic!"

One voice.

Super Sonic stopped. He stopped so fast and so suddenly, it felt like his own soul completely missed the memo. Like everything inside him continued to hightails it towards where Tails had been without him, leaving him empty. Hollow. Cold.

A vacuous space in the center of himself where there'd once been something. 

The chaos energy inside him didn't know what to do with that.

With so much… nothing.

Stunned, he could only float in place for a stupid second until he remembered he'd stopped for a reason. With a sharp turn, his stare locked onto a splash of orange amidst the blotchy colors of the rest of the world bleeding into one another. Like he was still moving too fast to see clearly. Like he couldn't catch up to himself.

"Sonic…" Tails's voice broke like it had on the comm, but it wasn't with pain guilt fear regret static.

Vision clearing, Sonic could see him now. At the edge of one of the hills overlooking Westopolis and the bay. Tails just rubbed at his nose with a sheepish sort of grin, like the explosion was a minor miscalculation. A hiccup. My bad, he could hear him saying, like he was standing in the middle of his workshop, covered in soot and singed fur, one hand on his hip and a fire extinguisher at his feet.

Like he was fine.

Like he hadn't been incinerated in the fiery inferno smoldering above them.

Tails lowered his hand, eyes shining as they looked up at him, reflecting the very sky Super Sonic was caught in as the satellite's remains fell all around him. He'd been on that satellite. Just seconds ago, Sonic had been so sure of it.

He'd been so sure he'd lost him…

Then Tails opened his arms to him and laughed.

All at once Sonic crashed back into himself, chest heaving with a sharp inhale as his heart lurched forward. 

Faster than a blink, Super Sonic barrelled into Tails and sent them toppling down the hillside. They smacked hard against the ground, but Sonic took the brunt of the fall even with the world spinning around them. His arms encircled Tails tightly, one hand protecting the back of his head while the other braced the small of his back as they tumbled and whooped like a pair of idiots. Pure joy radiated through him, burning brighter than the chaos energy coursing through his quills. It knocked the emeralds right out of him. The seven gems fell into the grass around them as the two mobians eventually rolled to a stop.

Sonic clutched Tails to him, shaking with breathless laughter as he felt his little brother hug him back just as tightly. "I'm here," Tails was saying, and it took a minute to realize he'd been repeating the words while Sonic's hands were trembling. "I'm here. It's okay, big bro. I'm here. I’m here."

"And you say I'm the one that's gonna give you a heart attack," Sonic wheezed, not bothering to give himself room to breathe if it meant letting go for even a second.

"Can't let you have all the fun." Tails smoothed his hands over Sonic's spines to try and settle him, his touch purposeful and grounding. "Deep breaths, big bro. You're gonna pass out."

"Nuh-uh," he argued, but filled his lungs with his next inhale anyway, then let all the air ease out of him.

"That's it. There ya go," Tails encouraged, but Sonic couldn't help his snort of indignation at being coddled and pushed away from him. 

Except Tails just tightened his grip; fingers curling in his fur like they'd be forced apart if he didn't. He hid his face in the crook of Sonic's neck, his breaths coming only a little too fast. But his hands were shaking, too, and his twin tails wound around them both as if they were enough to protect them from the next threat. 

Sonic didn't pull away. He just sat back, the eleven-year-old practically in his lap, and rested his hand atop Tails's head.

"Gave me a real scare there, pal," he said, voice low and gentle as he smoothed out his fur, picking at the grass and brambles they were both covered in.

"…Scared me, too."

Sonic's heart clenched, the open admission like a bludgeon to his protective instincts, even if his pride assured him Tails could handle it. After all, the proof had all but climbed into his lap. But now that he was looking at him—really looking at him—he could see his fur was mussed up from more than just a tumble at supersonic speed. A streak of blood stained his fur on his shoulder and there was a lump near the center of his back that filled Sonic with an angry fire hot enough to burn through the atmosphere when he so much as brushed against it with his fingers. 

Tails didn't flinch when he grazed it, but his muscles gave an involuntary spasm that rippled beneath his fur and his hold on Sonic tightened. It was enough to quell the roiling rage to a simmer. Something he could stick a lid on without worrying it would boil over if left unchecked. It wasn't what Tails needed from him right now.

But Sonic still wanted some answers.

"What happened up there?" he asked. 

Tails shook his head. "Just a bit of a closer call than I thought it'd be. But I'll be okay. I am okay."

Sonic instinctively bristled, prepared to be shut out of whatever it was he'd gone through. "Tails—"

"I'll tell you someday," he promised, pressing his paw over Sonic's heart. "I mean it. But right now we've got a lot of Eggman's mess to clean up. There's still six other titans out there and I'm sure everyone else is worried."

Sonic sighed, as exasperated as he could manage when he was still just glad this kid was alive. "Gonna hold you to that," he threatened, ruffling his fur to muss it up on purpose. "You owe me. Nearly shocked the Chaos Emeralds right outta my system."

"Says Mr. Guy-Who-Loves-Adventure," Tails teased as he pushed himself up to stand. "You should be used to it by now."

Sonic snorted when he was offered a hand up, but he took it nonetheless. "When I go gray early, I'll know exactly who to blame."

"Don't worry. I'll help you dye your quills, old man," Tails snickered, but it broke off with a wince as a sharp twinge ran through his back.

Sonic was quick to lay a supportive hand at his hip to steady him. "Look who's talking. At this rate, you're gonna be right there with me setting the record for the world's youngest old timers."

Tails sent him a look, but accepted the help nonetheless as he leaned his weight against him. "Did you really have to knock us all the way down the hill like that?"

"Heh. Well, in my defense, wasn't exactly thinking straight." Sonic scratched at his nose, giving him a not-so-subtle onceover. "Didn't bang ya up too bad, did I?"

"Nah. I'll bounce back," Tails assured him, giving him a pat on the back.

"You always do," Sonic agreed warmly as they took a few steps in tandem so they could start collecting the Chaos Emeralds on their way back up the hill while Tails alerted everyone to their status on his comm and checked in on everyone else as well.

Sonic just listened, taking in the rise and fall of his voice, his steady assurances and sighs of relief to hear that the world hadn't fallen apart in his absence. Even if it very nearly did. As far as Sonic was concerned, anyway.

But he was okay now. That was what mattered. And whatever it was that happened on that satellite—whatever reason Tails had for calling him seconds before disaster—he would trust that his little brother would come to him when he was ready. Because he'd be there for him. No matter what.

Keeping his arm looped around Tails’s waist even after they made it back up the hill, Sonic looked up at the smoke still fading from the sky. He tightened his hold on him. It felt like another lifetime, like another him had first seen the explosion and feared the worst. Tails followed his gaze, quiet again with all the calls taken care of and winded from the uphill climb. Through his labored breaths, there was the slightest tremor that traveled from his chest to where he stood pressed against his brother.

"…Scared me, too."

 "Hey, whatever happened up there," Sonic broke the silence, his voice drawing Tails back down beside him. "Whatever you did, I'll bet it was seriously way past cool." He glanced over at him, waiting to catch his eye before giving him a wink.

All too easily, Tails grinned up at him, the shape of his smile the spitting image of his brother's. "Way past is definitely one way to put it."

———

Five years later…

———

"You've been quiet all day, partner. Something going on in that big brain of yours?"

Everyone else had split off for the night. Team Dark vanished sometime after lunch, after Rouge once again tricked Shadow into accompanying her, and Team Chaotix had an appointment for their next case. Amy took Cream back home to Vanilla while Tangle and Whisper left to help Jewel out with some Restoration business.

Which left just Sonic and Tails lounging on the couch; the former picking up where Vector had left off in the game he'd been playing, tapping away at the controller while the latter watched.

Tails hummed in acknowledgement, so Sonic let him have a minute of quiet to collect his thoughts. He picked at one of Whisper's cinnamon muffins, crumbs scattering across the coffee table, but he didn't eat any of it. He hadn't had much of an appetite since slinking out of his lab earlier that afternoon.

It probably had something to do with the quiet and the way he'd been kinda clingy. Sonic had planned on going for a run as soon as Tails retreated back to his lab to tinker with whatever gadgets he had tucked away back there, but he seemed pretty content to stay curled up on the couch beside him. Still, Sonic could adapt. He kicked his feet up onto the coffee table and slumped back into the cushions as he wandered aimlessly around in a game he couldn't remember owning.

"Do you remember that time you went up against Eggman's seven fake titans?"

Sonic let out a low whistle. "Boy, is that a blast from the past. What about it?" 

When Tails didn't immediately continue, Sonic pressed the pause button, then shifted against the cushion to sit up and face his not-so-little-anymore bro. The sixteen-year-old fox tore his gaze from the screen to watch him instead, eyes bright from television's glow. Looking at him like that, for a split second, Sonic could still see the insecure, little fox kit he used to be in the way his shoulders hunched up as if to make himself smaller. To take up less space in the world.

Sonic draped one arm along the back of the couch, leaving space for him to lean into if he wanted it. No matter how big he got, there'd always be space for him.

Tails scooted closer and rested his head against Sonic's arm. "I needed to disrupt the satellite signal powering the Chaos Emerald vaults, but Eggman locked me out of the remote connection so I had to access it directly—"

"On the actual satellite," Sonic interjected, fingers drumming against the back of the couch. "I remember."

Tails released a long exhale. "Well, he set a trap. A way to slow me down so I wouldn't be able to unlock the emeralds for you in time. The same code that would disrupt the satellite's signal would also cause it to self-destruct. Eggman banked on me having enough self-preservation that I wouldn't engage it without trying to disable that function first."

"But you set it off anyway."

"I set it off anyway," Tails confirmed with a decisive nod. "It was the outcome with the highest percentage of saving people. The fastest way to help you guys. I thought I could get out in time. I should've gotten out in time," his voice lowered, eyes distant as if he was reliving the moment right there on their couch. "But I couldn't. Not on my own. I needed… help."

Sonic tried to follow him there, even if he didn't much like to relive that day in his waking hours. "So you called me."

"Not… exactly." Tails sat up straighter so he could look him in the eye. "I knew you'd come get me if I asked, but then countless lives would've been lost if the titans had gone on unchecked, even if just for a couple of seconds. Sometimes that's all it takes…" Tails's fist clenched as he dropped his hardened gaze to his lap. "I made the call to initiate the self-destruct in order to save people. I couldn't take that back. I couldn't take you away from them. Not again."

A younger Sonic would've snapped at him—would've argued over the value of his life with him until he wasn't the only one blue in the face. But at twenty-three, Sonic had fought more of these battles than he cared to count and never once walked away a winner. So he sat back, held his tongue, and let Tails explain himself.

"I called you to say goodbye," his voice lowered to a whisper, "I wanted to give you that, at least.”

He'd had a feeling. It wasn't one he dwelled on freely, but sometimes the thought wandered in uninvited. Moreso during the first couple of months after the incident, when everything was still fresh and closer to their present.

Before Sonic could respond, Tails pressed forward. "But then an older version of myself traveled through time with two Chaos Emeralds to save me. He said it was the only way. Because at the time, only the two of us knew what transpired on the satellite. We created a temporal paradox, a loop without a proper origin, but as long as it was contained between the two versions of me, nothing could disrupt it. That's why I couldn't tell you before. I wasn't sure… I didn't know if the future version of myself had told you what happened and if that would open up possibilities in the time stream that would botch the encounter entirely." Tails lifted his gaze to seek out Sonic's again, and he could see the eleven-year-old sitting in front of him like it was that very same day. "I'm sorry. I wanted to tell you."

"Nothing to apologize for, bud. I get it. I wouldn't want to mess up the time stream for that particular moment either." Sonic shifted the arm draped along the couch so he could cup the back of Tails's head, idly ruffling the fur there. "But if you're telling me all this now…" he drawled, moving to scritch behind Tails's ear. "Charmy wasn't the one who swiped Shadow's Chaos Emerald earlier, was he?"

Tails shrugged, muzzle quirking up on one side. "When he showed up with it today, I just had this feeling that it was time to make my move…" Tails explained. "I've been feeling it for a couple weeks now, to be honest. I had all the equipment I'd had on me that day and I looked close enough to how I remembered. I knew I probably had to go back soon. Just needed everything to align so no one would interfere. Today seemed good…"

Sonic tilted his head as Tails trailed off, his eyes still a little distant. "Well, you made it back in one piece, didn't you? Mission accomplished."

"Yeah. Mission accomplished," he echoed, but whatever was on his mind continued to fester. "I thought I made a mistake."

"Hm?"

"There were only three seconds left," Tails whispered. "I thought I messed it all up. I thought I killed us both—"

"You—"

"I was so sure it would work because it already had, but there was still the possibility I could've gotten it wrong. I could've caused a split in our realities. Created two timelines where I ceased to exist, except in this one no one would've known what happened to me and two of the Chaos Emeralds would be lost to time. How would any of you have known where to look?" Tails rambled, pressing his hands over his face. "I estimated the time of day with a standard deviation of a couple of seconds, but those seconds could've been what killed us—"

"Hey, hey, hey," Sonic hushed, shifting to wrap both arms around his little brother as he slumped against him. "You didn't. You're here. You're right here with me, see?" He gave him a firm squeeze, smile tugging at his muzzle as Tails hugged him back tightly. "Atta boy."

"Stupid…" he mumbled into Sonic's shoulder. "Why does this still work so well?"

"Heh. What're big brothers for?" Sonic huffed out a chuckle. "Listen, you can't live a life of what-ifs, bud. It'll drive you outta your mind. I should know. And I know you know that, too." He felt Tails's nod against his cheek. "You did exactly what you set out to do. And heck, you used the Chaos Emeralds to travel through time! When did you learn how to do that, huh? Holding out on your big bro?"

Tails snorted, but it got him to relax enough to pull back. "Figured if I could use Chaos Control, time travel was just an added boost. Like adding a supercharger to the Tornado's engine."

"Tch. You figured." Sonic rolled his eyes, but the warmth in them was nothing but fond. "Give yourself a little more credit. You did something incredible today, Tails. You defied time and space to save yourself. And not only that, you gave yourself a future to look forward to. Because who wouldn't want to turn out to be like you?"

It was Tails's turn to roll his eyes, though it was his own chuckle that betrayed him. "That's what I told me."

"And wiser words were never spoken," Sonic assured him as he gave his knee a firm pat.

"I dunno. Could make a case for the consequences of rewriting timelines and creating unsustainable permutations of past and future events." Tails grinned.

"Now you’re just being smart," Sonic snorted.

"Well, I am a genius." Tails bumped his shoulder to Sonics. "But I also learned from the best. Even eleven-year-old me picked up on that."

"Well, he's a genius, too. He knows what's up." Sonic slung his arm around Tails’s shoulder, this time his turn to watch as his brother picked up the video game controller to continue where Sonic left off. 

He let him, taking his turn to be content as he watched Tails figure out the game faster than he did and go farther than Sonic could. They said nothing for a few minutes, Tails working out the rest of his pent up feelings through the game while Sonic quietly processed what he'd just been told. He wasn't a stranger to time travel, not by a long shot, but even so, it wasn't what he thought the answer to that day had been. As much faith he had in his best friend, his self-sacrificial tendencies were something he couldn't help but take notice of. After all, he'd learned from the best, hadn't he?

But it wasn't with bitterness or disdain when he set his gaze on the teen beside him. That wasn't possible; not when he saw every age at once. Not when he was in absolute awe of how far his kid had come. 

"Tails."

"Sonic," Tails answered instinctively, matching his tone with the hint of a crooked smile.

"Thanks for saving him."

Tails blinked and paused the game so he could look at Sonic. In the light from the television screen, green eyes glimmered with a depth that took him back to a younger version of his big bro, who was trying to do everything in his power to be there for him. Because he wanted to be. Because he needed to be.

One tail curled around Sonic's back and draped over his lap, giving back the same reassurance he always gave so freely.
