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.
I may be imagining it where it doesn't exist but I wonder if they're trying to sneak a Wilhelm scream into every episode this season. 21 dusting off his Viceroy persona for the letter to Dean was callback of the week.
