Seeeeee Haymitch has a heart. Of course in the third book you question his motives but that is not important. And yeah he got hit in the arena or something, I'd have to consult the books again but he was given a prosthetic at the end. Katniss is pretty guarded and though there is reason for it, I do wish we got more of her before the Games and maybe before she lost her dad and had to pretty much raise her mom and sister.
