when Bronn, Jaime, and Tyrion are talking after Bronn arrives in WF (and doesn’t break Tyrion’s nose), he literally tells them: “I’ve seen the Dragon Queen’s army and her dragons and she’s gonna kick the KL force’s cute lil ass.”

Jaime knows Bronn. Jaime trusts Bronn. Bronn has been serving in the army as long as Jaime has, and he’s done it by Jaime’s side. Jaime knows and trusts that Bronn knows his battle shit. but does he ride off to protect Cers*i when he hears Bronn say she’s in real danger of being defeated? NOPE, he sure doesn’t.

but then the minute... the minute... he hears that one of the dragons has been killed and Euron managed to make a significant dent in Dany’s army, and that Cers*i actually has a shot in hell at winning, he is hauling ass to KL. 


Jaime didn’t leave WF and Brienne to protect Cers*i from Dany’s forces. he left to protect the rest of the world from Cers*i.

but Brienne, doesn’t know any of this. we do, but she does not. if she did, being a knight and skilled military strategist herself, Brienne would understand exactly what he was doing and exactly why he left. in fact, she would probably insist (with Sansa’s leave obvs) on going with him. and that is precisely why Jaime didn’t tell her... Brienne is the physical manifestation and human representation of what Jaime is protecting. he wants to save the rest of the world because Brienne is living in it, and because she showed him a world worth saving.
