"So this Sharon, this other Sharon, she told me about something that happened to her," Bucky tells him. He tries to keep his voice even; he has to sound sane. Steve's worried enough as it is, he can tell.

"She was on a long-term undercover assignment. For Fury. And evidently he was concerned about her attracting too much attention ... so he planted a bomb. And showed you a recording of her walking toward it. So you thought she was dead. And instead she was out in the cold -- for years."

He shakes his head. "I hadn't told her what happened to our Sharon. But it's too much like it. You know?"
