The last thing he remembers is going to find Steve. Steve had been taking on Thanos, trying desperately to not only save the universe, literally, but also to save Vision.

He doesn't remember anything after saying Steve's name. Looking down at himself, he sees the new arm is still there, along with everything else. That's good. He still has his kimoyo beads as well. Weird.

The gun rests easily in his arms as he looks around. Back alley, somewhere, definitely not the verdant greens of Wakanda. Creeping to the corner slowly, he looks out. He's in some sort of slum. Well, not his first time, but it's been a while. He looks around, carefully stepping out into the street. This isn't going to go well, at all....
