Wow just got to see the last episode (have been spoiler avoiding lately, harder than you think lol)
I think Cersei's probably not going to survive the next season either, she's made a fatal mistake by killing a lot of people she didn't strictly need to at Balor. She's consumed by a need for revenge and that included taking out most of her Highgarden competition (while leaving one of the most important members free to inact revenge) as well as the high sparrow, his minions and lots of bystanders. Unfortuntely that has not worked out well for her. She lived for her children and now they're all gone. I think she'll get progressively more ruthless and deranged from here on in.
I don't think that Jamie will even be able to kill her himself unless it's a murder/suicide. He may get to the point where he stands aside and lets someone else do it though. Something in his expression make me think he's well aware she's responsible for the destruction at Balor and indirectly Tommen's death. He killed a king to stop the wildfire being used in that way, now his own sister has gone ahead and done it.
As much as I like Arya, the whole time I had it running though my head "She's just been stabbed a dozen times in the abdomen! She should be dying, not running/jumping around the city the next day. Even a bit of morphine isn't going to let you do that. The should've gone for less and only let her be stabbed once or injured in a less vital area as it came across as being unrealistic. (You can't tell me that she didn't end up with a extensive blood loss and lacerated bowel at the very least from that attack- I know, it's TV reality ).
I wonder is Ramsey's dogs will end up with Arya's wolf? If they don't disappear from the story line (which is possible), that's where I'd put my money on them going. Arya's looking like she's going to go on a revenge rampage taking out her enemies one by one. If she can find her direwolf with a huge pack under her control it could help her with that and make her quite formidable in her own right.
Tommen didn't surprise me , he's been looking like meeting his end sooner rather than later from the start. I thought Margary might survive it as she's a stronger character but that's never stopped the show from killing off characters before. It's kind of a shame she didn't get out in time with Tommen just thinking she died. If she fled before Cersie knew she was still alive it could have made for some interesting story lines later on between her and Cersie as well as who the crown actually belongs to since the Baerathon line seems extinct apart from bastards now. I could see her going for the iron thorn under the right circumstances.
I'm starting to feel a little sorry for Melisandre. She's giving the appearance of a religious fanatic who's waking up to the fact that she's not infallible through her belief and is in a bit of a crisis state, tormented over some of the things she felt she had to do. She no longer has the same arrogance but still seems to have the will to live. I think she'll turn up again eventually.
I don't know what will happen with Dany and Jon. One thing she says when Asha is asking for her help is "she's not demanding, she's asking. Others are welcome to ask too." and she then decides to support her claim to the iron throne.
I think it's possible when she sees what's going on north of the wall, finds out Jon is kin (maybe) and realises Jon doesn't want the iron throne himself and could make a strong ally, she may decide to allow Jon some kind of title to continue to rule (with restrictions) in the north if he doesn't directly defy her. She's getting pretty cold and ruthless though at times. Lucky she has Tyrion there to balance her decisions, something she seems to realise deep down. Tyrion likes Jon, so he's got her advisor on side already.
There is the whole who is Azoi Ahai though. If Jon is Targayen and decides to push for the iron throne then it could play out quite differently. At the moment though, he seems to just want the North.
Speaking of Tyrion, without his father there to force the point, I suspect he'll release Sansa from marriage of his own free will if she asks. He always seemed to find the forced marriage distasteful anyway. I'm curious to see what Baelish gets up to now that Sansa has turned him down for now.
I think Sansa will let Jon be "King of the North" for now. She's been to hell and back and knows full well she's not a military tactician like Jon as is needed to get the North to rise up against their enemies. She knew Ramsey and made the correct call on that one and it seems unlikely Jon will ignore her advice next time. Even though she knew it was wrong, she couldn't tell him a better way to manage the fight short of "get more men" which at that juncture was not an available option for Jon. She messed up by not telling Jon that she had enlisted Little Finger's help. Bad decisions were made on both sides. Also Little finger offered her a way to take the throne and she turned it down, instead sitting by without any appearance of annoyance at Jon's rise in power.
I don't think Euron will be able to control Dany's dragons successfully long term. Anyone not a Targaryen (and maybe not even then) seems to have their lungs burnt out if they sound it. I'd imagine you'd run out of volunteers pretty quickly. I guess it depends on how long term the effect is and whether anyone non-mortal (Benjen anyone?) could sound it and live on. I can't see Dany using it, "mother" of her dragons and against slavery as she is.
