BTW, did they specifically say House wasn't having any kind of medical issues or delusions, here? Or did they just not mention it at all? Because there's a good extent to which the "processing" and the release of TEH RAEG could in fact be internal; and it would still explain that weirdness at the end, with it all Technicolor-dreamy; and the sudden day/night shift.

Someone else brought up the detail that the beach had been full of life/people and then suddenly *poof* they were all gone. I don't know. I think I'm just going to try to forget the whole thing until we see how it shakes out in the fall.
