Fairly decent opening episode, as you'd expect, a good look at where all the characters are at the moment.
Is it bad I'm mostly rooting for Cersei? I fucking love her character. Although her prophecy, all of which has come true so far, doesn't bode well for her. Jamie (who is actually one of the good guys, really) to do her in before she can commit her final unspeakable act which would kill the entire city.
Danaerys story continues to bore me to tears. Need a big season from her and Tyrion now they're where they need to be. But the more Missandei on screen the better.
Samwell's character will be hugely important in story development and whether Jon's barmy army can help defeat the white walkers. I don't get why they have to have Gilly and the baby though.
We won't see an end to the white walker storyline by the time this season's over, but a handful of main characters will be offed.
Bailish to get sick and tired of Sansa's constant rejection, he fucks off to king's landing with knights of the vale, does bits with Cersei and betrays Sansa - probably takes out Dorne or some shit. He then wants a dragon so betrays Cersei and buddies up to Dany and marries her. Dany can't have child so Bailish brings the desperate Sansa back in the mix for child bearing. Little Finger to win the game of thrones.
Also, Theon to betray everyone he holds dear so Qyburn can give him a new throbbing zombie dick.
