I think the season will end on LS, would be an awesome cliffhanger. I'm sure she won't be cut, otherwise there would be no point introducing Beric and all the resurrection stuff ib the first place. As for no information on Michelle's page, I think they can be quiet about it on purpose, to make it a surprise with even more impact.This episode was the best premiere this show had, I think, maybe on par with S3. The only scene I hated was Tyrion+Shae, I just can't stand Shae at all. Some scenes fell a bit flat for me, like Brienne's interaction with Margaery and Tyrion with Bronn meeting Dornishmen without Oberyn on foot on some road, but otherwise it was very good. I was sceptical on Oberyn cast, but now I'm completely sold. The Jon Snow trial was one of the best actions Kit put out on the show, also loved Aemon lines.
A lot of hilarious things too. I chuckled when Jaime waved at Qyburn with his fake hand, was smiling at Hound at chickens and lost it when they showed the statue of Joffrey first, only to cut it to Jack Glesson standing in almost the same. Jack's action is gold again, we mean to hate his character but I can't stop cheering every time he's on screen. Like Viserys in S1, pity he died too quickly.
