Bucky had a mother and father and a sister called Rebecca back in the 40s, right? And Bucky "died" in the war, so his family would've gotten a hologram telling them Bucky's dead. Well I really want to see Bucky post-winter soldier, having to deal with the fact that his family are dead, that his little sister whom he'd protect with all his life, is dead. Steve came to terms with Peggy. Let Bucky come to terms with Becca and his family.
