Re: James Buchanan Barnes aka The Winter Solider
He cracked jokes, and was a bit more talkative than Cap, I think.
Plus I read a story in Captain America #600, I think it was, where Steve and Bucky are at a dance for the troops. Steve is a wallflower, content with sitting on the sidelines while Bucky is out dancing and I think with a few different girls.
He tries to get Steve to get out and dance to, have fun and enjoy himself. I think after talking for a while Steve says, "Remember when I punched out Hitler? That was fun."
