The Tyrant

Early on in this episode, House exclaimed "It's three years ago!" when he realized that he was working with the old team - Foreman, Chase, and Cameron. It became apparent rather quickly, though, that things at Princeton-Plainsboro are still very far from normal. He may be back, but House isn't back. Right now, he's more like the little kid that your co-worker brought to the office and he just won't leave your cube. That and the little kid is way smarter than you are.
