Walt Jr.'s been on a wild and entirely terrible ride in these final episodes of "Breaking Bad." (Except for the time he got to meet Saul!) He learned the truth about his dad, intervened in a knife fight between his parents, and most brutally in the last episode felt compelled to tell Walt to "just die already!" But RJ Mitte tells us that, in a way, he's still rooting for Walt, and he says deep down Jr. still has some sympathy as well. Vulture caught up with the actor to talk about the show's final run, filming intense scenes with Bryan Cranston, and what's ahead. But first, a belated happy birthday!
