So many questions...
Glad to see Roose dead, but still waiting for Ramsey to get his. After all the stuff he's done to Theon, Sansa, Roose, Walda, the baby, etc. I can't even picture a death horrible enough for that brat. Should be interesting to see how things go - seems like he's willing to piss off a good chunk of the north, as well as probably losing Walder Fey as an ally with the death of Walda.
And the stuff with Tyrion and the two dragons. Awesome. I see a lot of people thinking his interaction with the dragons confirms he's a Targ, but I'm not sure if that's a lock or if it just meant they didn't see him as a threat/enemy. Still... it was awesome watching him unchain them. Can't wait to see more of them in action.
There's also the matter of a shot that was in one of the trailers for this season. It showed a knight in what looked like Targaryen King's Guard armor fighting someone who looked like a Stark bannerman. It looked a lot like a possible flashback to the Tower of Joy!
The "next episode" teaser they showed for next week was awesome - that is totally Ned at the Tower of Joy in that flashback.
Really looking forward to seeing that played out and finally confirming some things one way or the other.
