Okay, now I have to know what was in that promo!
I so don't care about Thirteen returning. I'm sure Olivia Wilde is a very nice person but she can't act. Plus, since she's supposed to have this big movie career now, it seems strange that she would return - maybe she'll only be back for one or two episodes and then leave permanently.
You know, if House stays married and actually works making the marriage a success, that would be genuinely interesting.
