It was all the stupid cat’s fault.
That was the long and short of it. Bucky vanished into thin air and left Sam alone, and Sam was okay with that. Really, he was. If Bucky wanted to vanish, if he wanted to take Clint and Wanda with him and leave Sam behind, that was fine. Sam had been left behind before. Barnes could have had the good grace to take his cat with him, was all.
There was nobody else to feed it. As far as Sam knew, no one else even knew Bucky had a cat, but Sam did. And Sam couldn’t leave the damn thing to starve, no matter how pissed he’d been at Bucky, so he brought it home. He bought a litter-box. He researched the best kind of cat food. He made friends with a different kind of vet than the ones he usually hung out with. And if he sometimes found himself talking to Alpine at night, when Rhodes was with Stark’s family and Lang was with his and everyone else on the team except for Sam went home to the people who were important to them, nobody had to know that. If the only person Sam had outside working hours had four legs and a tail, no one had to know that.
At least... until the damn cat slipped out his apartment’s window and into a goddamn superhero fight happening outside. He’s smart, Bucky used to say. Knows who he likes and who he doesn’t. He knows our scents, you know. And Sam hadn’t believed him for a second, but now he was up in the sky and Alpine was on the ground looking up at him as if there wasn’t gunfire and lazer blasts all around him and the fucking cat was the only thing Sam had and it was going to get itself killed like it was nothing.
Diving to the ground and scooping Alpine up wasn’t a conscious decision. It was instinct. It was the same thing that once convinced him to open his door wide enough for a couple of fugitives to slip into his living room, the same thing that had him throwing the Accords across the table without putting his name on the dotted line, the same thing that had him in a ring shop on leave between his first and second tour trying to decide whether Riley was the kind of guy who’d want a diamond. Instinct, for Sam, had been pretty hit or miss over the years.
He just never thought it’d be the thing that got him killed, as all.
The explosion wasn’t like any he’d seen before. It was a flash of bright light, an almost pleasant warmth spreading across his face, a force just strong enough to shove him backwards and onto the ground. It was disorienting enough that the lost a few minutes in between, closed his eyes and opened them knowing time had passed. For a moment, he lay on the ground with his heart in his throat, in three places at once.
Part of him was on that street, explosion still rocking his mind. Part of him was in a field in Wakanda, watching his fingers turn to dust. And the last part was in a desert, the world ending around him. It was that last part that seemed most prominent, that last part that gripped him tight and refused to let go.
“Riley,” he breathed, shooting up and searching for a body in the sand. There was no body. There was no sand. There was no blood between his fingers, no pain radiating through his chest.
What there was, he realized after a moment, was a cat.
Sam stared at Alpine for a moment. He was cleaning himself, utterly unbothered by whatever had just happened. Around them, the battle that had been raging moments before was gone. Sam focused on the cat. The cat wasn’t hurt --- that probably meant Sam wasn’t, either, even if his mind screamed the contrary.
“Okay,” he said, squeezing his eyes shut. “All right.” Bringing a hand up to his comm unit, he pressed the button experimentally. “Uh, guys? Cap here. Do you copy?” Static. “Rhodes? It’s Sam. Do you hear me?” Nothing. “Lang? Danvers? Strange? If anyone reads me, I need extraction.” The silence gave him all the answer he needed, and he nodded his head. “Okay,” he repeated, looking down at Alpine. “Just me and you, then. We’ll find them. They’re all right. We just... We gotta get to safety. Someplace to lay low. Right? Right. Lucky for us, I know just the place.” He scooped the cat up and zipped it into his jacket, nodding to himself as he started walking.
Whatever happened had pushed him out of city limits, but not far. Sam trudged forward, glancing around for any noticeable differences. Things were different in an indescribable way, but one thing was the same. The safe house he’d taken over after Bucky’s disappearance was still standing. The key in his pocket miraculously fit into the lock. When the door closed behind him, Sam breathed a quiet sigh of relief. “We got this,” he told Alpine soothingly, patting the cat’s head as he walked into the safe house. “Me and you, buddy, we...”
A jacket on the back of the chair that wasn’t his. A notepad on the table he didn’t recognize. A pink hairbrush on the floor, utterly out of place. Footsteps behind him, quiet and cautious but not silent enough to avoid being picked up by a mind already twelve levels of paranoid. Pulling a knife from his belt and gripping it tightly, Sam whirled around and held the blade at throat level, ready to strike...
...Only to let it drop slightly when greeted with a familiar face.
“Barnes?” The name caught in his throat, tight and uncertain. From his jacket, Alpine meowed.
