Bucky always said the battlefield stripped everything down to truth. No disguises, no polite lies, no time to pretend you didn’t care when someone’s life hung by a thread. Feelings you could ignore in daylight became deafening under gunfire. And somewhere in the grit of their latest mission—the kind where intel came half-baked and extraction was a fantasy—Bucky found himself staring straight at a truth he’d been dodging for months.
He cared about John.
Too much.
-
The mission had gone to hell three hours in.
What was supposed to be a clean infiltration turned into a labyrinth of collapsing intel, mercenaries with better tech than expected, and a facility full of experimental weapon prototypes humming like angry bees. The kind of place where one wrong step meant there wouldn’t be anything left to bury.
Bucky moved through the dark corridors with practiced efficiency, metal arm braced for impact, rifle steady, breath even. The sounds of distant fighting echoed—shouting, the crack of gunfire, machinery powering up. But underneath all that, he searched for one thing only.
John.
He wasn’t supposed to be part of this op. Originally, Bucky had argued it wasn’t necessary—John’s skill set wasn’t tailored for tight corridors and suicide missions. But John had insisted, stubborn to the bone, eyes bright with the reckless conviction that he wasn’t leaving Bucky to run this alone.
And Bucky had felt something tighten in his chest at the time. Annoyance. Worry. Something deeper he hadn’t wanted to name.
Now, with the entire complex one spark away from obliteration, that unnamed feeling throbbed through him like a second heartbeat.
He turned a corner—and froze at the sight of an overturned support beam pinning a man beneath it.
Not just any man.
John.
-
“Bucky—” John’s voice was strained, tight with pain but steady enough to tell Bucky he wasn’t dying. Not yet. “You’re late.”
Bucky dropped to his knees beside him, metal fingers digging under the beam. “You’re gonna complain right now?”
“Only if it keeps you from panicking.”
“I’m not—” He stopped. Because he was. His pulse was racing, hand shaking just enough for him to notice, and he hated that John could read it.
“Hang on,” Bucky gritted out, lifting the beam in one brutal push that tore through the concrete floor. John slid out, coughing hard.
Before Bucky could help him up, alarms shrieked overhead—low, metallic, warning of an imminent system detonation.
“You’ve gotta be kidding me,” John muttered, wincing as he got to his feet.
“No time to rest.” Bucky grabbed his arm, hauling him upright. “We need to move. Now.”
They ran, boots pounding across collapsing platforms, the entire facility groaning like a dying beast. Lights flickered overhead, sparks rained down, and the floor shook with each distant explosion.
John stumbled once. Bucky caught him instantly—hand around his waist, grip firm.
“You’re hurt,” Bucky growled.
John laughed breathlessly. “You noticed.”
“Not the time.”
“Never is.”
Maybe that was what did it—those words, tossed out casually, yet hitting Bucky with more force than the bomb they were running from. Never is. Because they’d had moments before—quiet ones between missions, bickering ones over gear maintenance, soft ones when exhaustion lowered their walls—but they always skirted around what simmered beneath.
As if both of them knew acknowledging it could unravel everything.
But as the building shook violently, sending them slamming against the wall, Bucky realized something with cutting clarity:
There might not be another time.
-
They reached the central lab—the only route to the extraction point. And of course, because fate had a sick sense of humor, it was crawling with armed mercenaries.
John cursed under his breath. “Got any brilliant plans?”
“One.” Bucky chambered a round. “Don’t die.”
John huffed a laugh. “Touching, really.”
Before Bucky could retort, bullets erupted across the room. Bucky dragged John behind a steel pillar, shielding him with his own body as metal chips flew.
“Bucky,” John hissed, “you don’t have to—”
“I’m not losing you.”
The words came out harsher than intended. Raw. Unfiltered.
John blinked, momentarily stunned—not by the gunfire, not by pain, but by the sudden weight of that confession.
Bucky knew he’d messed up the second he saw the expression on John’s face. Too honest. Too revealing.
But there was no time to take it back.
He surged forward, metal arm deflecting gunfire as he took down the nearest merc. John covered him, firing with sharp precision despite the injury. They moved like a single force—Bucky clearing the front, John watching the flanks, instinct guiding every motion.
They fought like they’d been doing this for years.
Like they trusted each other with everything.
When the final mercenary fell, Bucky grabbed John’s vest, pulling him close as another tremor shook the building.
“You good?” Bucky demanded.
John grimaced. “Define ‘good.’”
“You’re alive. Good enough.” Bucky didn’t let go.
John stared up at him, eyes dark and unguarded. “Earlier… you said you weren’t losing me.”
Bucky clenched his jaw. “Can we not do this here?”
The ceiling cracked overhead—concrete raining down.
John stepped closer, voice low. “If not now, when? This place is gonna blow, Bucky.”
Which was exactly the problem.
Bucky didn’t want this—this realization, this fear, this raw honesty—to be shaped by dying. He wanted it to be shaped by living. But he didn’t have that luxury.
He swallowed hard. “Because I care, alright?”
John froze.
The building thundered again—another warning. But neither moved.
Bucky forced the words out like they’d been lodged in him for months. “I care. More than I should. More than makes sense on missions like this. And it scares the hell out of me.”
John stared at him with something fierce and bright, something that punched oxygen out of Bucky’s lungs.
“Good,” John said softly. “Because I’ve been scared too.”
The confession hit Bucky harder than any explosion.
But there was no time—none.
He grabbed John’s hand. “Move.”
-
They burst through the collapsing hallway just as the detonation countdown hit its final seconds. Fire chased them, heat roaring like an inferno. Bucky didn’t think—he threw himself and John through the last structural door, metal arm slamming it shut just as the blast thundered behind them.
Silence rolled in after the boom—a heavy, ringing kind. Bucky lay there, chest heaving, John sprawled on top of him, both of them alive by inches.
John groaned. “Next time… we’re picking missions that don’t explode.”
Bucky let out a breathless laugh. “Yeah, like we ever get a choice.”
John shifted slightly… and that’s when Bucky realized their hands were still clasped.
Neither pulled away.
John looked down at him—sweaty, dusty, bruised, alive—and smiled.
“I meant what I said,” John murmured.
“So did I,” Bucky replied quietly.
Maybe the world had nearly ended around them. Maybe they were still lying on the floor of a half-destroyed corridor. Maybe everything hurts.
But for the first time, Bucky felt like something had finally clicked into place.
Not because the mission was over.
But because he knew, with absolute clarity, that he would face a thousand more like it—
—as long as John was on the other side.
