What amazes me is the absolute absence of any sort of censure. It would appear that Kurt's behavior is not in question by anyone. At all.

How freakin' weird is that? That a cast member could go absolutely crrrazy outside and then stroll on-set and not one of the cast thought "Uh-oh... he's in a mood". I can't believe for one minute that the morale on that shoot didn't hit rock bottom after all that shit.
