Oh Barristan. :-(
The legend that he was, didn't deserve to die in a backstreet alleyway. Saying that, it's better than just living out his days on a small hold somewhere, forgotten by the people he fought for and protected. Missed opportunity there though; he should have gone out like Leonidas.
I liked the way they handled Cersei and the Faith Millitant. She seems so desperate and lost, clinging onto anything that resembles power and manipulation. She can't see the forest through the trees, and it's going to be so sweet. It's borderline naivety.
The Rhaegar mentions, as well as Sansa's scene, definitely seem to be reminding the show watches who he was, and the implications regarding Jon's parentage. They can't just have a character go to Jon "Oh by the way...", without reminding the audience who those names are. I half expected Littlefinger, when Sansa states that Rhaegar kidnaped and raped Lyanna, to correct or at least question that idea. Still, with the show having to cut down on any nonessential material where they can, it seems pretty obvious that the nature of Lyanna's "kidnapping" and the tourney at Harrenhal etc are to be important going forward. There's only one reason why it would be.
Haven't got an opinion on the Sand Snakes. Pretty "meh" at the moment, going by the show. Can go either way.
Everything's bubbling at the moment; I'm looking forward to it all boiling over. There's a lot of underlying tension; it's half way between tedious and exciting. I just hope the dramatic scenes this season seems to be promising deliver. I think I'm most looking forward to how things play out in Winterfell; so many paths cross there, or will do. Given Littlefinger's comments, I wouldn't be surprised if he's playing the long game and has some sort of deal with Stannis in the background. I did find the kiss awkward though, and I question his decision to return to King's Landing. Naive, arrogant or just plain stupid.
