Bucky only remembered one month of things? So did he only wake up recently? Steve guessed that it was possible, it would explain why he still looked so young. Frozen from something... not in the mountain though. There must be a different cause.

"Were you asleep all those years?"

It made sense why Bucky didn't really act like Bucky anymore. He didn't remember who he was or much of anything. Didn't remember rescuing Steve from all those alleys or having his back during the war. But Steve was going to help him, he had to.
