There are a million interviews with the cast/crew since Sunday's episode, but this one really stuck out.
Director Alan Taylor said the following regarding Sunday's finale (SPOILERS ABOUND) -
[GOT finale teaser]“I love the fact that these two come back, they’re both lethal, and I just wanted to give the impression, as much as possible, that one of them is going to die. But you’re not sure which one.”
“Something is coming very soon between them, and it will be violent but surprising.”
Mind you, he could have been fucking around, but something is happening. Yes, the post title is vague (obviously) but the spoiler info explains why I kept that vague.
