The radiation chamber hummed with deadly energy, its walls glowing with the sickly red light that meant death to any organic being. Jim's hands moved frantically over the controls, rebooting the warp core even as his body began to betray him — cells breaking down, DNA unraveling at the molecular level.
Through the transparent aluminum barrier, Spock pressed his palm against the surface, his usually composed features cracking like ice under pressure. "Jim, you must stop. The radiation levels—"
"I know what I'm doing, Spock." Jim's voice was already rougher, strained. He could taste copper in his mouth, feel the familiar burn that meant his body was failing. But the ship... the ship and everyone on it would live. That was what mattered.
The warp core stabilized with a mechanical sigh, its chaotic energy settling into the steady rhythm that would carry them safely home. Jim turned from the console, his legs nearly giving out as he stumbled toward the barrier where Spock waited.
His friend — his everything — stood rigid with the kind of control that Jim had learned to read like a book. Spock was falling apart inside, and trying desperately not to show it.
"Our ship is safe," Jim said, pressing his own palm against the barrier to match Spock's. Even through the protective material, he imagined he could feel the warmth of Spock's skin.
"Jim." Spock's voice cracked on his name, and Jim saw something he'd never seen before — tears gathering in those dark eyes. "I am... I am sorry. For everything. For the lies about my feelings, for the distance I maintained, for every harsh word, every moment I chose duty over—"
"Spock." Jim's legs finally gave out and he slid down the wall, but kept his hand pressed to the barrier. his gaze lingering on Spock’s form still as the Vulcan kneeled down to stay level with him, "Stop. You don't need to apologize for being yourself."
"But I do." The tears were falling now, tracking down Spock's cheeks as his careful composure shattered completely. "I have been a coward. I have hidden behind logic and duty when the truth is that I... that you..." His voice broke entirely.
Jim felt his vision blurring, darkness creeping in at the edges. His body was shutting down, systems failing one by one. But Spock's tears — those were more important than his own pain. "Hey, look at me."
Spock's eyes focused on him with desperate intensity.
"I forgive you," Jim said softly. "For everything you think you need forgiveness for. But Spock — you never needed it. You've been the best friend I could have asked for. The best everything."
"Jim, please—"
"I love you." The words came out easier than Jim had expected, maybe because he was dying and nothing else mattered anymore. "I've loved you since that first day on the bridge. Maybe before that. I should have said it sooner, should have—"
"T'hy'la." The word fell from Spock's lips like a prayer, like a confession. "I love you. I have always loved you. In every way it is possible to love someone."
Jim smiled, even as his vision darkened further. "I know. I always knew, even when you were being stubborn about it."
Spock's palm pressed harder against the barrier, as if he could somehow reach through it, somehow touch him one last time. "Jim, I—"
But Jim's hand was already sliding down the wall, his body going limp as the radiation finally claimed him. His eyes remained open, still fixed on Spock's face, but the light behind them was gone.
"T'hy'la," Spock whispered to the empty chamber, his voice raw with grief. "My friend. My beloved. Forgive me for not saying it sooner."
