Chapter Text
Sam became aware not with a rush of pain or a sudden jolt, but with a slow, creeping return to sensation. It was the cold he noticed first—a cold that was not merely the absence of warmth, but the negation of it, the annihilation of every memory of comfort he’d ever known. It was so vast and consuming that it pressed against his consciousness like a weight. He tried to inhale reflexively and found there was no air. No need. He wasn’t breathing, wasn’t alive in any human sense.
Just aware.
The darkness was complete, so absolute it seemed to have a texture. It folded against his skin like wet cloth, sank through him, pressed into every cell. He opened his eyes—or thought he did—and saw nothing. A darkness so profound it made him question if he even had eyes anymore.
Something trembled in the far distance, a violent, echoing boom without direction or source. The vibration rippled through him, scraping at the edges of his mind. His thoughts were fragile, like shards of glass rattling in a box.
The Cage.
Panic surged through him, a flaring, spiking brightness in the dark. He tried to move, tried to stand, to shout. Nothing. His limbs were unresponsive, as if he were submerged in tar. He summoned all his will and forced sound out of his throat:
“—Michael—Lucifer—!”
It came out as a whisper that vanished an inch from his lips. Like there was no air to carry it. No physics at all.
Something stirred near him, a subtle shifting of presence. For a moment, he thought it was Lucifer approaching—cold fingers, cruel laughter—but instead there was a ragged intake of breath.
“Sam?” The voice cracked, young, terrified. “Is that you?”
“Adam?” Sam croaked, or thought he did. He tried to reach out. His arm floated slowly forward, through the black, until it encountered something solid—a shoulder, narrow and shaking.
Adam Milligan. His little brother by blood. A boy who had died before he ever really got to live.
Sam’s fingers dug into Adam’s coat, reassuring himself they were both real. Here, at least. Together.
Adam was shivering so badly that Sam felt it through their tenuous contact. “What…what happened?” Adam whispered, voice strangled. “Where are we? I can’t see anything. I—I can’t feel—” His breath hitched into a sob. “I can’t feel time.”
Sam clenched his teeth. He had to be steady. For Adam’s sake. “It’s the Cage,” he said hoarsely. “Lucifer’s Cage. We fell.”
“Oh, God,” Adam choked out. “Oh, God—”
In the darkness, something moved. A hurricane of rage and power, a cyclone of malignant purpose. The darkness didn’t lighten, but it pulsed—just once, like an engine catching fire. A heatless wind tore past them, pulling at Sam’s consciousness, scattering his thoughts like dry leaves.
Lucifer’s voice followed, booming without direction, without volume. It was not a sound so much as an idea forced into Sam’s mind:
I will not yield, Michael!
And a second voice answered, equally immense and crackling with righteous fury:
Then you will perish.
Sam flinched as the pressure of their conflict built. It was like being at the epicenter of an earthquake that never stopped. No up, no down—just raw force battering the edges of the dark.
He curled an arm protectively around Adam’s shoulders. The kid was gasping for breath that didn’t exist. His panic was a living thing, palpable in the void.
“Adam,” Sam said as steadily as he could. “Listen to me. It’s going to be okay.”
“Don’t—” Adam’s teeth chattered. “Don’t lie to me.”
Sam swallowed. “Then I promise you this: I won’t let them touch you.”
I will not let them touch you.
A promise, bright and solid in the murk. Maybe the last good thing he had left to offer.
The world—or the lack of it—shook again. Sam felt the seconds crawl by. But in here, time was a joke. A trap. Something unrecognizable.
He remembered Dean telling his about Hell’s worst trick: its time didn’t match the world he’d left behind.
One second in the Cage could be a decade here. Or more. His brain shied away from calculating it, but already he felt the weight of centuries pressing at the edges of his mind.
He focused on Adam’s shoulder. The tremor of another heartbeat.
You’re not alone. He wanted to say it again, but his voice wouldn’t obey.
Another concussion of celestial force swept through them, and Adam let out a strangled scream. Sam pulled him closer, shielding his smaller body with his own. There was no real physics here—no gravity, no heat, no air—but the motion helped him remember who he was. Anchored him to the scraps of self he had left.
In the distance, Lucifer and Michael grappled—two powers without limits, locked in an endless cycle of fury and regret. Sam felt their hatred coil around him like barbed wire. Each time they collided, it tore through the Cage itself, scraping across reality.
He didn’t know how long he sat there, arms around Adam. He only knew that time fractured. One heartbeat might be a second—or a century. When he tried to think of the world beyond, it felt like a story he’d once read, lifetimes ago.
Dad. Jess. Dean. Cas.
He closed his eyes—not that it changed anything in the darkness—and tried to remember Dean’s voice. The familiar, gruff affection. Hey, Sammy. But the memory slipped through his fingers, soft as ash.
He wouldn’t forget. He couldn’t. Because if he did, there would be nothing left of him.
Adam shifted in his hold. “Sam,” he whispered, voice so small it broke Sam’s heart. “I don’t want to be here. I don’t want to—”
“I know,” Sam whispered. “I know, buddy.”
“How…how long?” Adam sounded on the edge of tears. “How long will it be before…before…”
Before the end. Before Lucifer noticed them. Before their minds came apart.
Sam swallowed past the thickness in his throat. “I don’t know,” he admitted. His voice was steadier than he felt. “But I’m here. I’m not going anywhere.”
“Promise?”
“I promise.”
The darkness pulsed again, this time with a flare of pure, ancient grief. It rolled through Sam’s mind like a tide. He realized, dimly, that it came from Michael.
Brother, Michael’s voice rang, suffused with something heartbreakingly sad. It didn’t have to be this way.
It did, Lucifer hissed back. You never understood. Father never loved us. None of this was love.
Their hatred ignited again, a nova of colliding grace that made Sam’s vision—such as it was—strobe white for an instant. When it passed, the blackness seemed even deeper.
Sam tightened his hold on Adam. The kid was crying silently, shaking so hard Sam could feel every quiver. He felt something twist inside his chest—a resolution sharp enough to hurt.
If I’m stuck here, he thought, then I’ll protect him.
It wasn’t a hope. Not really. Hope felt too thin, too breakable in a place like this. But it was a purpose. A reason to keep clinging to his mind, even as the timeless dark worked to strip it away.
He lost track of himself after that. Time blurred. He knew the darkness. He knew the tremors of Lucifer’s rage and Michael’s sorrow. He knew Adam’s shivering, the way his breaths hitched and caught.
Sometimes, he thought Adam slept. Other times, he thought he did. But there was no way to be sure.
Moments came when the Cage felt almost quiet, when the two archangels drifted apart like storm fronts receding. Sam would try to talk in those moments. Sometimes he could shape words, sometimes not.
“Sam,” Adam said once, voice scratchy and thin. “Are we dead?”
Sam didn’t answer right away. He didn’t know what counted as death anymore. “No,” he said finally. “We’re…we’re here. We’re together.”
Adam didn’t speak again for what felt like years.
In the dark, Sam dreamed. He dreamed of fire and stone and screams. He dreamed of Dean, calling his name. Of Castiel’s hand on his shoulder. Of sunlight, warm on his face.
Sometimes, he’d wake—if waking was a thing—and realize centuries had passed between heartbeats. He would still be here, with Adam in his arms, and the blackness would still be unbroken.
And so it went. Time lurching and stuttering, elastic and cruel.
Ten years might pass in what felt like a breath. A single argument between Michael and Lucifer could last an entire human century. Sam felt pieces of himself erode—his sense of scale, of memory, of language. But he never let go of Adam.
One eon—one second—he realized he could almost distinguish the shapes of the archangels, just barely. Pale outlines moving in the dark, locked in perpetual collision. When they struck each other, the Cage itself cracked and shuddered. Sam thought, distantly, that if they kept fighting like this for another thousand years, they might even break free.
But that thought was too large. Too far away. All that mattered was here, in the circle of his arms.
He didn’t know how long it took before the darkness began to feel almost familiar. Like an old, hated blanket he’d been forced to wrap around himself.
In that darkness, Adam began to speak again.
“Sam?” His voice was steadier this time. It had been…decades? “I think…I think I remember Mom’s face.”
Sam swallowed. “Tell me.”
And Adam did. In a voice raw from disuse, he described her smile, her hair, the way she smelled of soap. Sam listened, holding the words close, fighting to remember that this was real. They were real.
Later, when the fighting quieted, Sam tried his own voice. It rasped out of him like wind through broken glass.
“Adam.”
“Yeah?”
“I won’t let them take you.”
“I know.”
Decades passed again. Or maybe it was only minutes. But eventually, the darkness shifted, and they began to talk more easily. To share the fragments of memory that still survived the cold.
Sam knew they would never leave here. Not on their own. He knew the Cage wasn’t a prison they could escape by force of will. But if they had to stay, at least they would stay together.
It was enough to keep him sane. Almost.
The next time Lucifer and Michael clashed, Sam didn’t flinch. He simply tightened his grip around Adam and closed his eyes, counting the years as they slipped away.
⸻
Twenty years in darkness.
Twenty years of surviving.
Twenty years of remembering why he had to.
And somewhere in that darkness, something like hope—thin and battered—refused to die.
