Killing the Blackfish offscreen...really? I mean, come on - you can do better. And the whole Arya scenes were dumb. Surviving the attack last episode is one thing, but one episode later she already jumps around as if it never happened. Time jump ofc...just affecting this storyline.
Another funny thing: Straight before the attack Arya acted totaly out of character - so people came up with several theories that the whole thing was staged involving Jaqen H'ghar and whatever...folks, this season you get straight forward solutions all the time. And ofc Danny and her dragon...IF she crushes the enemy forces with her dragons in episode 10 and the last scene is another "Hail to the queen, breaker of chains...blabla" scene...
So, what will happen next episode? If they continue their route Jon will loose when suddenly the armies of the Vale save the day - Battle of Blackwater revival. Though, i don't think they do the same thing again. Maybe Little Finger betrays him or simply waits until the battle is over and kills the survivors. And there was a Lannister/Frey party scene at the Twins in the trailer. See potential for betrayal there once again ^^ Whatever, the preview for e9 looks pretty nice.
I liked the Mountain, Hound and Jaime scenes though, still hoping for a good finale.
