How am I the first one to be writing about this?!
The good: I loved the first half of this episode--the Freys' murder, Arya making friends with those charming Lannister soldiers, Jaime's clear discomfort at Cersei's descent into madness. Though I don't really care about Bran, I'm a bit miffed that we didn't see Jon getting news about him being at the wall, but perhaps that will come. The scene with little Umber and little Karstark bending the knee was sweet. While I wasn't a huge fan of Sansa undermining Jon in front of everyone, her new attitude toward Littlefinger was a breath of fresh air. For perhaps the first time ever, I am firmly on Team Sansa. The Hound is still working his patented blend of sarcasm and touching, though I worry his constant use of 'cu**' will make the word lose all meaning.
The meh: I thought the second half of the episode dragged a bit, but I understand they're setting the stage for the whole season. Dany managed to be a bit a boring even in her tiny bit of screen time, but hopefully that will be the last time we say that of her? Euron Greyjoy... is he supposed to be funny or obviously not? I'm not sure he'd be a particularly interesting character anyway, but now I think I'm just not invested in the King's Landing storyline since so many of the most interesting characters are gone.
Bonus: Jorah's grayscaled arm. Poor Jorah.
