To be clear, I HATED the way this whole thing wrapped up. I feel like Jaime's entire redemption arc was undone. I mean, it's not like he did anything horrible in this episode like he used to (and at least he killed Euron, who was easily the crappiest character in the show's entire run), but I thought he FINALLY had a revelation at the end of last season that his sister is a POS and his love/obsession with her is the primary reason why he's lived such an evil life. He finally broke away from her to do a good thing, and then... he tries to go back to save her. And to make matters worse, he does so out of a stupid plan hatched by Tyrion, who at this point should have REALLY stopped trying to redeem Cersei. Speaking of that plan, I don't know why Jaime ended up outside the castle walls when he did, since he was trying to sneak Cersei out the secret passage, but I guess we needed a reason for him to fight Euron.
ANYWAY, all that aside, in a way, the prophecy did kinda come true in that Cersei might have lived had both of her brothers not tried to smuggle her out of the city, because it ultimately led her to her doom. I hated how they seemed to want us to sympathize with her after all the horrible **** she's done, but bad writing is kinda the key to season 8. Still, in a roundabout way, she did sorta die because of her brother(s). So, win?
