You Haven't Aged A Day:
By AssssinOfRome
Steve sucked in a breath, staring at the door in front of him. Could it be? No, it was impossible. Foolish to think. Yet he couldn't quite shake it from his mind. Jack couldn't be dead. It was impossible!
They had met several times, first time being before the war. Bucky had introduced them. Jack had been a dashing, dark-haired beauty and he'd been... well Steve. Skinny, small, easy to forget. But he couldn't deny it; Jack had given him a special smile. The kind he'd only seen before, in bars that he shouldn't have really been frequenting.
"This shouldn't be so hard." He whispered to himself. "It's not Jack. It can't be Jack. So just knock." Yet, despite this, he could still feel his hands trembling. He was Captain America, for goodness sake, not some quivering maiden. He could knock on a door!
In 1940, they'd met again. By this point, Steve had taken the serum and was Captain America, advertising superhero. He'd been feeling pretty low, when there was a gentle tap at his shoulder. Captain Jack Harkness was there, in all his glory. Of course, he didn't recognise Steve; not now that he'd bulked up, but he did know Captain America and wanted to see the 48 States, if you catch my drift. They'd had a few drinks, and Steve couldn't remember much of the following evening. All he could recall was waking up alone, with a photo of a handsome gentleman clutched in his fingers. He'd kept that photo with him always. It was in his pocket as he crashed into the ice.
Steve closed his eyes and counted to ten. By the time he reached nine, his finger was already jabbing the doorbell. Alarmed, he opened his eyes. Oh, why had he done that? His stomach fluttered with nerves. What was he going to do? He could run! Yes, that would solve everything! He could hide in the bushes and peer through, just to check if it was Jack. He took a step back, and knew it was wrong. Bravery. That's what he stood for. That's what he needed.
They'd met again, once Steve had freed Bucky. Jack had been at the camp, waiting on his bunk in nothing but his hat. He'd felt so delightfully naughty, kissing Jack with everyone around, all-seeing eyes blind to their love. It still brought a blush to his cheek. Together, they stolen hundreds of manuscripts, and led thousands of missions. Sometimes, they saved. Sometimes, they lost. But they were always together.
There was a bustling from inside. A male form passed against the window, too quickly for Steve to see. His heart leapt into his throat as he noted the man had dark hair. A pulse thrummed in his head, like the beating of an eagle's wings.
Jack was indestructible. Steve swore he'd seen him fall at least ten times, yet after ever battle, he seemed unscathed. Heck, he was even grinning that same cocky grin! Jack always kissed him extra hard when he raised that point. It usually shut the blonde up.
Steve glanced down at the piece of paper in his hands; a print-out from SHIELD head-quarters.
Seemingly human male with apparent immortality. Investigate.
The door creaked open, and Steve screwed his eyes shut, not sure if he wanted to see what was in front of him.
Apparent immortality.
It had to be.
It couldn't be.
"Steve?"
Captain America opened his eyes to see the same, kind eyes. The same dark hair. The same cocky grin.
Captain Jack Harkness.
