A lot of people say they ruined jaimie's arc. I dont think so. He was always flawed. But in the end he was redeemed by dying as an honorable man. This is game of thrones, not everyone has that Disney storybook ending. Heck I dont think any one does. He said it himself you dont choose whom you love. Cersei was his drug and he was addicted to her. And he died how he wanted in the arms of the one he loved. The valonqar prophecy never existed in the show either. Jamie killing a pregnant woman (his child) would have been messed up. I just think he should have been scorched with cersei, instead dying by fallen rubble.
We all know Jaime had a thing for Cersei, that's fine. Same is true of Cersei towards him, yet she still tried to get him killed.
I mean, why doesn't he stick by her side instead of going to fight against the White Walkers? What's the point? Once that's done, why not just get back straight to Cersei? His feelings towards Cersei are not new...why did they make it seem as such? Like...he just realized at the end how much he loves his sister?? For real???
But..I mean...fine. Make him go to Cersei, why the f*** does Euron absolutely want to kill him? So much so that he rather do that than get back to his Queen who he thinks is pregnant with his child, while she's under siege???
Not to mention the enormous coincidence of Euron 1) suriving the destruction of his fleet, 2) not drowning, 3) swimming alone towards the secret passage, 4) getting there at the exact same moment Jaime walks by there.
Man...this show became so bad. Terribly frustrating.
