I saw that Cuddy confronted House. But I don't know what was said or the utter chaos that ensued.

His hallucinations have proved to be more than just crazy dead chick--House imagined the whole deal with Cuddy, and is still on the vikes, so he got taken off to rehabs or whatever.

it turns out he hallucinated everything and how he's in the nuthouse

NOT EXACTLY WHAT I WANTED TO HAVE HAPPEN
