I was afraid that the show would start going the route where all the characters get all mopey and emo about Kutner offing himself and I was kinda right. The good part is that it shouldn't last too long with the season almost up.
What's with that ending though. If House is gonna start seeing dead people all the time, this could lead to Kal Penn coming back every once in a while.
Jennings would make great marketing sense, but he's been critical about the show's production on his blogs. I dunno if he'd have the stamina to put up with the show's style, specifically the director's adoration of older female contestants.
