You’re better than this, Bellamy. You’re better than this. You’re better, better, better. The words kept racing through Bellamy’s mind, creeping in during any quiet moment, tugging at him whenever another kid took off their wristband. They struck him like a bolt of lightning whenever Delia or her sister crossed his line of vision, leaving him breathless for however long it took him to remember he’d shot the Chancellor and was out of options—which he’d cut down into a matter of seconds in the last days. He’d been doing his best to avoid both of them since last night. He didn’t need to grapple with the added guilt of knowing he’d driven a wedge between the two sisters. And out in the woods, axe in hand, boar in sight—he could put the Moss siblings out of mind.
Atom took a step towards the boar and Bellamy held out a hand, a silent command to stop. “She’s mine.”
He lifted his axe, zeroing in on the boar as if sniffed the ground, oblivious to the group of hunters hidden in the brush. All of his tension, his anger and fear, seemed to glimmer in the creature’s wide, black eye, and if he could just—
A twig snapped behind him, and he whirled around, axe flying instinctually out of his hand before he could process it was Charlotte—Charlotte Moss—staring wide-eyed at him as the axe thunked into the tree trunk beside her, level with her eyes.
“Charlotte,” he said, shoulders slumping with relief that she wasn’t a Grounder, quickly chased by a new kind of tension. “I almost killed you.”
Charlotte wrapped her arms around her torso, looking between him and the axe. “I’m sorry.”
“It’s okay,” he said, feeling the gallop of his heart begin to slow. “But you should be back at camp.”
Charlotte shook her head. “That guy who was dying. I just…couldn’t listen anymore.”
Bellamy stepped forward, pulling his axe from the tree. “There’s Grounders out here. It’s dangerous for a little girl.”
Charlotte stuck up her chin. “I’m not little.”
He saw something familiar in the hard set of her eyes; stubbornness ran in the Moss family, it seemed. He sighed. “Okay, then.” He pulled a knife from his jacket and held it out to her. “You ever killed something before?”
Charlotte shook her head, but took the knife from him, turning it over in her hands.
“Who knows?” said Bellamy, patting her shoulder. “Maybe you’re good at it.”
////
Charlotte was not good at it. Her aim was sloppy and unsure, but she was an eager learner, and Bellamy found he enjoyed explaining how to track, how to approach a beast without startling it, how to angle the wrist to throw a blade just right. Her enthusiasm for his teaching reminded him of Octavia when she was younger, when he could claim her rapt attention with nothing more than mundane stories of life out and about on the Ark.
They crouched in the brush by a stream—a thin vein of water through the earth—and waited. Bellamy knelt close to Charlotte, the others a handful of feet away.
He’d been itching to ask her about Delia, itching to parse out the tension between her and her sister, itching to know what Delia said about him within the confines of their tent. But he didn’t care, couldn’t care. And he was enjoying his time with Charlotte. There was no need to sully it.
Charlotte, it seemed, disagreed. “You’re right about the Ark, about taking off our wristbands,” she said, voice hushed as they watched a rabbit dart out of the brush. “Delia won’t let me though.”
Bellamy spared her a glance, scanning the bitter curl of her mouth and trying to decide how to proceed. He could double down, could add one more ‘dead’ kid to the Ark’s tally. Or he could side with Delia just this once. Charlotte was her sister after all.
“Delia is just trying to look out for you,” he said, landing somewhere between the two options.
Charlotte looked up at him, confusion drawing her brows together. “But you said the Ark needs to think we’re dead. I thought, you know, without her here…”
She held out her wrist, her bracelet glinting in the early evening sun.
Bellamy nodded his head towards the rabbit. “Your prey is gonna run away any second now.”
She snapped back into focus at that, lifting her knife and squinting at the creature on the opposite side of the water.
He didn’t want to contradict himself, but he could picture the way Delia’s eyes would harden at the sight of her sister’s bare wrist. He didn’t want to draw her ire any more than he already had, especially after last night, after hearing her voice tremble and seeing her eyes shimmer with tears. He’d only ever seen her so wide-eyed and desperate once before, and he did his best not to think about that night.
He cleared his throat and forced himself to come back to the present. He’d just do his best to avoid topics regarding bracelets, Arks, and stubborn older sisters.
Charlotte launched the knife into the air, and it flipped as it sailed over the water, landing handle down more than a foot away from the rabbit. It leapt back into the brush, and Charlotte’s shoulders slumped.
Bellamy patted her arm. “You’ll get it next time.”
Somewhere in the distance, a scream split the air, and the whole group stood at attention.
“Look,” said Charlotte, pointing down at another rabbit that raced past them, darting over the roots along the forest floor. And then there was another and another, and a squirrel and a horde of beetles that made Charlotte shriek and jump away.
“Bellamy, look!”
Bellamy lifted his head in time to see a sickly yellow cloud slipping between tree trunks some fifty feet away. It was getting closer, inch by inch.
“What is that?” asked Charlotte, stepping closer to Bellamy.
Atom stepped forward, fingers reaching towards the encroaching cloud. The second the yellow gas touched his skin, he cried out, yanking his hand back. “Run,” he yelled. “Run!”
Bellamy snatched Charlotte’s wrist and took off, slowing his pace just enough to keep her from falling behind. “Come on!” he called, not chancing a look over his shoulder. “There are caves this way!”
////
Through the fog at the cave’s entrance, Bellamy could tell when day sank into night. But he couldn’t bring himself to sleep. He told Charlotte to get some rest and laid down on the ground beneath her perch, but every time he closed his eyes, he saw Octavia—swallowed by a cloud of yellow gas, screaming into the night.
He kept his eyes open and forced himself to stare at the damp stone of the cave, glistening in the low light.
That conjured another unwanted image—Delia, teary-eyed and desperate as she stared up at him beneath the starlight. Just say it. As if it was simple. As if admitting it would do anything other than heighten his panic whenever he saw a kid walking around camp with their wristband intact, transmitting Earth’s survivability back to the Ark.
It felt as if his feet had never truly hit the ground. From the moment he shot the Chancellor, he’d been a tangle of nerves, floating from one moment to the next. With Monty trying to make contact with the Ark, he was constantly teetering on the edge of condemnation. And he’d ruptured his relationships in the process—Octavia, Delia. Once the Ark abandoned them for good, he might be able to finally breathe. He could convince his sister—and Delia—to look him in the eye again.
Beside him, Charlotte screamed.
Bellamy pushed himself up, stumbling towards Charlotte as she thrashed against the rock, crying out.
“Charlotte.” He shook her shoulder. “Wake up.”
Charlotte shot up with a gasp—her rigidness slumping into arms-around-the-torso shame as she realized where she was, who she was with. “I’m sorry.”
Bellamy shook his head—an instant dismissal of her apology. “Does it happen often?”
Charlotte looked away, and in the dim light, he could see her cheeks flush with embarrassment.
“It’s alright,” he said. “What are you afraid of? You know what? It doesn’t matter. The only thing that matters is what you do about it.”
Charlotte furrowed her brows, eyes darting towards him in confusion. “But… I’m asleep.”
Bellamy breathed out a laugh, his fondness for the kid before him growing as she blinked down at him. “Fears are fears,” he explained. “Slay your demons when you’re awake, and they won’t be there to get you when you’re asleep.”
Her confusion grew. “Yeah, but…how?”
She looked down at her wristband and then back up at him, brows raised in a silent question. Was this the demon she was meant to slay?
He shook his head and pointed towards her boot. “Let me see that knife I gave you.”
She withdrew it from inside her sock and he took it from her hand, gripping the handle between their faces. “Now, when you feel afraid, you hold tight to this knife and say screw you, I’m not afraid.”
He flipped the knife in his hand, offering it to her handle-first.
She grasped it hesitantly, looking between it and Bellamy.
He nodded once, a silent encouragement.
“Screw you,” she said, her voice soft as she closed her eyes and gripped the knife. “I’m not afraid.”
When she opened her eyes, he raised his brows and shook his head. You can do better than that.
She squinted her eyes shut and sucked in a breath. “Screw you. I’m not afraid.”
Bellamy smiled, patting her shoulder. “That’s more like it.”
Charlotte smiled back and tucked the knife back in her boot.
“Slay your demons, Charlotte,” he said, scooting back to the spot where he’d been laying. “Then you’ll be able to sleep.”
When she spoke again, her voice was so quiet that he had to ask her to repeat herself. She looked down at her hands and sighed.
“I wish I was your sister instead.”
Bellamy’s mouth opened in shock, and he was struck silent for a moment. He’d been so anxious to re-earn Delia’s favor, and here was her sister, believing she’d be better off without her. How much of that was because of the things he’d said?
“You don’t mean that,” he said, inching back towards Charlotte.
“She sides with the Ark. She doesn’t care what they did to me.”
“That’s not—” Bellamy let out a breath, unsure exactly how to explain. “She and I may disagree on certain things here on the ground, but up there?” He pointed a finger upwards. “She never stopped fighting to get you out. She put up posters, protested outside council meetings, nearly got herself floated—because of how much she cares, Charlotte.”
Charlotte blinked down at him, lips downturning as she processed this new information. “But then—why does she want them down here? Why isn’t she on our side?”
Because I’m selfish. Because she’s right, and I won’t admit it.
He breathed out, dispelling those thoughts. “Because we just—disagree. It’s complicated. But you should never doubt that Delia loves you.”
Charlotte sighed, laying back down into sleeping position. Bellamy took that as the end of the conversation and went back to his own place. In the quiet, he heard her mumble, “Screw you. I’m not afraid.”
He smiled.
////
Delia curled into herself on the third floor of the dropship, knees drawn to her chest as she listened to Jasper mumble and groan in his sleep. Her heart hadn’t stopped racing since the fog appeared and kids started filing into the dropship, Charlotte nowhere among them.
What kind of older sister was she? She was so occupied with plucking and planting, seeding a garden behind the ship. She hadn’t realized it had been hours since she’d seen Charlotte, and now she was out there, possibly dead.
“Delia, could you help hold him still while I change this bandage?” asked Octavia.
Delia nodded and stood, crossing to Jasper and kneeling beside him. She pressed down on his shoulders, stilling his unconscious stirring as Octavia peeled a bloodstained bandage from his wound. He flinched in his sleep, and Delia pressed down more, doing her best to keep her touch gentle against his sweat-slicked shoulders.
The ghostly pallor of his skin reminded her of her father, of those last weeks after the medication rations ran out. He looked half-dead long before he took his last breath. The last days were like this—sweaty and mumbling and barely lucid. The air in their room was stiff and mournful, her and her mother and sister still and sad as headstone angels perched beside his bed.
It was a lot like this, like Octavia’s stone-faced expression as she stared down at Jasper.
“He’s gonna be okay,” Delia said, though in her heart, she didn’t believe it.
Octavia nodded and let out a breath as she sat back. She ran a hand over her temple, the stress of the day written plainly on her face.
“Bellamy will be okay too,” added Delia, and Octavia lifted her eyes.
She nodded. “Charlotte too.”
Just the mention of her sister’s name made her heart sputter and thump against her ribs, but she did her best to smile. “Thanks.”
They say in silence for a moment, the quiet broken up by the scrape and click of Monty working on the radio. Delia wanted to ask Octavia if Bellamy had admitted anything to her, but it wasn’t Octavia’s responsibility to speak for her brother. And she had no desire to come between them.
Instead, she asked her what it was like in lockup.
Octavia’s eyes shot up to hers, annoyed. “Lonely. Miserable. What do you think?”
Delia nodded. “I mean, I figured. It’s just—Charlotte is so angry and distant, and I thought some insight into what her last four years were like might help me get through to her. She won’t talk about any of it.”
Octavia softened at that, shoulders slumping. “Were any of the rumors true?” asked Octavia. “About you getting your mom floated?”
Delia's eyes widened in surprise. She was refreshed by Octavia’s bluntness, and she felt herself grow fonder of Bellamy’s sister. Strong-willed and smart. Unafraid to look Delia in the eyes and ask the hard questions. She’d been chased by mumbles and stares—both on the Ark and on the ground—and it was nice to be able to tell her side of things.
“I was careless,” sighed Delia. “I was having what should’ve been a private conversation with her out in the open. All I was thinking about was keeping it away from Charlotte. Protecting her from our mother’s nastiness. Charlotte being hidden was a given of our lives. It was how it had been for almost a decade, and it never even crossed my mind that she might—”
Delia paused, feeling shame and frustration rise in her gut. “But was she drunk. Drunker than she’d ever been. And she let it slip. Too direct. Too loud. I was an idiot to think she was capable of being discreet. And now she’s gone, and Charlotte—”
She gestured towards the woods outside, towards the fog that might’ve claimed her. “After I started becoming more—politically active, some allies of the council took it upon themselves to spin the story of my mother’s floating in their favor, painting me as some cold-blooded killer who was responsible for the very thing I was protesting.” Delia shrugged. “But it all stemmed from that one stupid decision. So they weren’t entirely wrong.”
Octavia shook her head. “You were trying to protect your sister. You can’t blame yourself for that.” Her voice was hard and sure. She had an easy sort of confidence that made Delia almost believe her. Almost.
“Right, well—lockup,” said Delia. “If you’re willing to share anything, I’d appreciate it, but don’t feel obligated.”
Octavia looked up at the ceiling, pondering for a moment. “It was isolating. I was treated more like cattle than a person, you know? At sixteen, it hurt. I can’t imagine how it would feel at—what? How old was she when she went in?”
“Eight,” said Delia.
“Eight,” echoed Octavia. “She just needs time to reorient herself, I think. To remember that not everyone is out to get her.”
“Our circumstances don’t exactly reinforce that idea.”
Octavia laughed. “True. But you’re not out to get her. And neither am I, if she ever wants someone else to talk to.”
“Thank you, Octavia,” said Delia. “Really.”
“You’re a good older sibling,” said Octavia, mouth tightening in momentary annoyance. “Can’t say I have the same thing at the moment.”
Delia tilted her head to the side, letting out a breath as she assessed Delia. “Bellamy is—doing his best.”
“Bellamy is a controlling dickhead,” said Octavia.
Delia bit back a laugh, once again charmed by Octavia’s bluntness. “I mean, right now, yeah, but he’s—” She let herself drift off, not wanting to delve into Bellamy’s misdoings.
“I know,” said Octavia, and there was something in her voice that made Delia believe she did know, that Bellamy had told her some, if not all, of what he’d done. “He just won’t let me live my life.”
“He’s trying to protect you,” said Delia.
“I know,” said Octavia, picking at a spot of dirt on her boot. “But he could be less of a little shit about it.”
Delia smiled, but before she could reply, Jasper groaned. Octavia turned her attention to him, laying a cool damp cloth against his forehead and muttering to him, low enough that Delia could make out the words.
“Hey!” called a voice from below. “The fog’s cleared!”
Delia was on her feet in an instant, clambering down the ladder and pushing her way through a mess of bodies, out into the newly clear air.
She darted past the wall, stopping only long enough to cry Charlotte’s name every handful of seconds. The woods were quiet—terrifyingly, gut-churningly quiet. Every time she blinked, Charlotte flashed behind her eyelids—skin bubbling and raw, eyes glazed and distant.
“Charlie!” she called, leaning against a tree to catch her breath.
Somewhere in the distance, a scream ripped through the air.
Delia shot off in that direction, feet stumbling over the uneven ground. But she could see Charlotte—distant, obscured by a tree trunk, arms wrapped around herself.
“Charlie,” breathed Delia, panting as she skidded to a stop before her sister. She ran her hands up her arms, assessing her for damage. “Are you hurt?”
Charlotte didn’t reply, her wide eyes staring at something over Delia’s shoulder. Delia turned, breath catching in her throat at the sight of the mangled, rasping body on the ground before them.
She heard footsteps racing towards them and there were Bellamy and his boys, similarly breathless at the sight of Atom’s—was it Atom?—body, the skin blistering and oozing.
“Son of a bitch,” cursed Bellamy, kneeling over Atom. He held his hands out before him, unsurely hovering over Atom’s endless wounds.
“Kill me,” rasped Atom, and Delia instinctually stepped in front of Charlotte, blocking her view.
Bellamy looked up at Delia, eyes wide and unsure.
Behind her, Charlotte stepped towards Atom and Bellamy, something extended in her hand. It took Delia a moment to recognize it as a knife, the blade’s sharp edge glinting in the sunlight. When had she gotten a knife?
“Don’t be afraid,” said Charlotte, nodding down to the knife she held out to Bellamy.
Bellamy took it, hand slow with hesitation.
“Charlie, head back to camp, okay?” said Delia, stepping forward to place a hand on her shoulder.
Bellamy nodded to his boys. “You too. Make sure she gets back safe.”
Delia knelt on Atom’s other side as the group departed, watching as Bellamy held the knife, loose and helpless in his hand.
“Atom,” said Delia, laying her palm against his shoulder and doing her best to ignore the way his skin moved like liquid beneath the material of his shirt. “We’re gonna help you, okay? You’re gonna be okay.”
With her hand on the shoulder closest to Bellamy, she lifted her forefinger—out of sight of Atom—pointing to the bulge of his carotid. She looked up at Bellamy, nodding once. Putting the knife there would offer him the quickest end.
Bellamy looked at Delia, then Atom, then the knife, then Delia again. His eyes were wide and panicked, and the knife remained limp in his hand.
Delia felt herself soften, felt herself recognize, for a moment, the man before her—not a killer, not calloused or self-serving. None of those. Soft-hearted. Unsure. Too kind too kill.
Beneath them, Atom choked.
“Hey,” said Delia, her voice low as she looked at Bellamy. She turned her hand palm up, an invitation to give over the knife. “It’s okay.”
////
Bellamy didn’t remember handing Delia the knife. One moment, it was leaden weight in his hand, and the next, Delia had it braced gently against Atom’s neck.
She settled into the grooves of the tree roots she sat on, making herself comfortable against Atom’s side.
“Can you see, Atom?” she asked, her voice honey-sweet.
Atom shook his head ever-so-slightly, choking at the motion.
“Well,” said Delia. “Above you, the sky is so blue. Vibrant and bright, like the edge of a flame.”
Bellamy couldn’t look away from her. He knew the soothing tenor of her voice was meant for Atom, but he felt himself lulled all the same. Delia smiled at Atom, her eyes wide and kind, and in his peripheral vision, he saw Atom’s twitching begin to slow, his breath growing steady.
“There are no clouds,” she continued. “Not one. And the trees above us are so lush. Their leaves are swaying ever-so-gently in the breeze.”
She slipped the knife into Atom’s neck, and blood began pooling over her fingers and onto the ground.
The expression in her face didn’t change as Atom began to sputter and choke, blood streaming from his mouth. She smiled down at him, smoothing his hair with her free hand.
“There’s a bird singing just above us, Atom. Can you hear it?” she asked, and Atom started to reply, mouth opening as his eyes lost focus and his lungs exhaled one last time.
Delia stayed like that for a moment, hand on his hair, knife in his throat. Bellamy’s chest ached as he watched her, filling with a sudden flood of emotions he could neither count nor name. But in the center of it all was a sudden certainty: if he ever found himself choking on the precipice of death, he only wanted Cordelia Moss to put him out of his misery.
