IT'S ALL SPOILERS HERE, UNLESS YOU'RE UP TO DATE.
Loved the last episode of this season. Lots of nice moments. Littlefinger's comeuppance. Sandor Clegane and Brienne discussing the Stark girls. Bron taking Podrick for a drink while the queens and lords discuss politics. The undead ice dragon in action, a Tyrion v Cersei audience, Jamie being told off by Brienne, and trying to reason with Cersei. Jon getting together with Dany. Some great lines by Tyrion. All good stuff.
Couple of points:
Someone in this thread has said 'now that Jon's not a Stark'. That's not right. He is still a Stark; by birth, on his mother's side.
Anyone else think Jamie is torn between two women? Cersei has his heart (if not his desire), but Brienne seems to have his soul. Really like that. The chapters in the book dealing with Brienne taking Jamie back to Kings Landing are brilliant too, as we get to see both sides's perspectives. I like how they've continued that plot line in the post-book era.
Speculation:
I think Jamie's going North, to keep his word. Have to wonder how he's going to be received though. When he pushed Bran off the walls of Winterfell in Episode 1, Season 1, Bran didn't know who he was. I'm sure he'll know now though. If Arya get's wind of it, I would be surprised if she didn't add him to her list, and deal with him quite promptly.
I think Cersei is pregnant, but I suspect it's Euron's child. To discuss the plan whereby he pretends to flee to the Iron Islands, he and Cersei must have had a meeting. We also know that Cersei believes a woman's most powerful weapon is 'between her legs' (from her advice to Sansa, when she as at King's Landing). He's made himself look weak, fearful and foolish by so easily fleeing Westeros. I wonder if she used sex to 'persuade' him to do that? Telling Jamie that the baby was his to keep him bound to her, would be quite a 'Cersei' thing to do.
My only criticism of the season, is the pace and reduced number of subplots, that have brought us here. I suspect it's because of the contraints of money, filming, and because the books weren't written yet, but I miss the depth of the earlier seasons.
