I'm just remembering about episode 9 being pushed back a week and dug through this thread to find the reason cause I couldn't remember and:
I think I read that the other day and dismissed it as a joke, and waited for someone to post the real reason but it didn't happen. Turns out it is the real reason. Wow, HBO, you couldn't have picked a different time slot? [very mild TV series spoilers]Episode 9 is the most crucial episode of the season, just like the previous seasons really, and you delay it... -_-
It is because of Memorial Day.
