Winter's still for a beat, watching him, but then a little of the tension goes out of him. If Steve is asking that, then he might be listening to reason. "You trust the people around you," he says. "We help each other see what's real." He pauses again, then adds, "It's tough. I know."

But he's never really trusted himself; there's no way he could, with what he's done, and what's been done to him. And trusting other people was a long time coming. Yelena, Kate, Cortana, and Steve. Hopefully Steve.

He offers Steve his hand again. There's still a brownie to split.
