So I have this theory.T he bodies in the crypt (including Ned Stark) are going to rise. Originally I thought this because we saw Arya running, terrified in the crypt, there doesn’t seem to be a limit on resurrecting bodies, and , from a TV perspective it means you can have Sean Bean back.
After episode 2 I have more reasons. Cause, oh we just decided to keep everyone who isn't fighting in the crypt. What could go wrong? Oh and we conveniently left Sam down there too (although I'm a bit unclear, he said he wouldn't stay down there, but we saw him down there so maybe he's just visiting)? Oh, wait and Tyrion too? Yeah sure, let's leave some big name characters down there cause NOTHING is going to happen. And let's not forget the little girl we decided to quickly bond with in episode 2 (she's probably gonna die and Davos will have to face her wight). Also, if you've seen the trailer for episode 3? Dany says "The dead are already here." Yeah, yeah that could be referring to the army of the dead marching on Winterfell, but I think it's the moment of realization that the dead are already inside the walls.
Okay, rant over.
