Some random thoughts:
1. Wonder what stupid scheme Littlefinger is up to now that his whole Sansa plot was a complete disaster.
2. I CANNOT see Jon abandoning the watch. He must know his ultimate fate is to face the white walker ice king. Or at least he should feel that way as he is one of the few to see the threat first hand and survive. How can he care about the game knowing what the actual threat is? Makes no sense to me.
3. There's not nearly enough time for Samwell to become a maester. And no way are the going to dedicate the time he deserves. He must come up with something huge to fight the white walkers with, like an obsidian lightning rod or something. Otherwise I don't see how he has any impact on either of the central conflicts.
4. I kinda hate the show now. I mean, it was great as an alternate take/companion piece to the books for me, but the books are the real meat. Having to find out what happens feels like someone just reading me the cliffs notes of the books. It's my own damn fault because I can't stop watching though. Damn you grrm
