Out of all the possible answers Steve had envisioned Bucky giving, that wasn't one of them. He wasn't even really entirely sure what it meant - what was it that Steve reminded him of, and what was it Bucky wanted to forget? Because Steve would have assumed that Bucky wanted to forget about the Games, about all of the violent, awful, traumatizing things that had happened within the Arena, and he didn't understand how he could be a reminder of that.
But if Bucky hadn't meant that, then what did he actually want to forget? He'd said things weren't the same, so was he worried that Steve would expect Bucky to be the same person he'd always been. Steve knew better than that, knew how tragedy and trauma could change a person - hell, he wasn't the same person he'd been before he lost his Ma, not even close.
"You think you could explain that to me a little more?" he asked softly, carefully. Because he didn't understand, and Bucky hadn't said anything that was convincing enough to keep him away, not a damn thing.
