Because they resolved the Vogler thing and seemed to get everything back on track. The only thing really left would be to get Cameron back, or somehow Vogler finds another way to get at House. Anyway, Vogler was a complete ASS on tonight's episode. Attempting to sack Wilson and Cutty, too, simply for standing up for House? And damn, the "medical issue" for the episode...that was heart-wrenching.
I hope I never have to make a decision like that!
Despite all that happened, I don't remember there being any indication of a season finale, and if there is one, I'd think they would play it in May like most other shows. Next week wasn't indicated to be new, though I haven't seen the episode and they didn't seem to include Cameron in any of the preview scenes.
Eh, anyway, House kicks ass and he got angry this episode. That was awesome!
