Season 5, Episode 1: “Live Free or Die”
4. Four seasons ago, Walt was a chemistry teacher in a shaky marriage who gets diagnosed with cancer.
2. All this guy needed was some affection from his wife and a little respect at the office.
1. Now the dude is a fearsome villain who is more Darth Vader or Michael Corleone than some goofball teacher making meth in his underwear, which is a shame for morality but it is damned fine television.
