Could you expand on how Jaime will be removed from the King’s guard and what will happen when he is?
So I think that Cersei will remove him, most likely after hearing via Qyburn/RonCon that Jaime and Brienne have a bit of a thing going on - I can’t find the post, but others observed a few years ago that RonCon is headed back to KL, and in conversation with Cersei may mention how he came about the big old bruise on his face. Qybs can meanwhile testify to the whole romcom airport dash that is Jaime’s race back to the bearpit. And I think someone mentioned Randyll Tarly might even have something to contribute here but I can’t remember what it is so.
Anyway all of this taken together, I think Cersei is going to for once leap to the correct conclusion - that JB are going canon - and decide Jaime can no longer be trusted, and so removes him from the KG. The pretext may be that she just states he’s dead already, it may be that Loras is proven to be alive after all and so there’s still a spot requires for undead Gregor, or it may be she just uses the Barristan Precedent and gets rid. Either way, Cersei believes she’d know when Jaime has died, so it won’t be a matter of her fearing him dead. She’s going to remove him because she considers him a traitor now.
As for where that sees Jaime’s arc turning - it’s a lot of internal stuff like I mentioned before, as Jaime’s arc is quite an inward looking one:
Firstly, it reconfigures his relationship with Tommen: Tommen is no longer the king he must serve but purely his son, and Jaime’s next steps in that relationship must be made as a father, not a glorified guard.
Secondly, it ends his “marriage” to Cersei (see prev post), and forces him to finally realise himself as an independent autonomous human being who must shape his own destiny (nice job jam you’re only 34)
Third, it reframes the legacy he’s pursuing - is he looking for glory to fill the white book with, or is he looking to do what’s right whether it’s on the record or no. It’s Jaime having to embrace his legacy as an individual rather than as a cog in an institution he doesn’t believe in
Fourth - I know this sounds like shipper talk but I honestly think the possibility remains on the table - it frees him up for marriage lol. Jaime has previously reflected that marriage is out of the question for him as a member of the KG, whether he wanted it or no. But as his romance with Brienne is realised there is no way someone like Jaime, who has been raised in a society that has marriage on the mind pretty much constantly, is not going to think: hey, I’m a single lord, she’s a single lady, we’re in love and I don’t want to dishonour her - therefore??? Like it’s not GOT, JB wouldn’t even have the language to describe an ONS/casual fling. Courtship and marriage go absolutely hand in hand in their world, that’s why Jaime couldn’t get marriage out of his mind w Cersei, against all logic and reason. So if his vow of perpetual bachelorhood is removed - yeah go figure
Regardless of how it all comes to pass, I basically just think it’s an absolute given that 1) Cersei will figure Jaime for a traitor and remove him from the KG, 2) Jaime will have an identity crisis. GRRM may have already written it….
