Other halves ... or better halves? Jaime, Cersei and Brienne

I’ve jumped ahead a bit in my reread to reread the “good” bits of A Feast for Crows (that is to say, I like the entire novel, but I was really interested in focusing on the Jaime, Cersei and Brienne chapters), and specifically in talking about Jaime’s last chapter where he throws Cersei’s letter onto the fire.

From the beginning of Jaime’s POV, Martin has juxtaposed Jaime, Cersei and Brienne for us, and the burning of Cersei’s letter is another of these instances, (though not as immediately obvious as it was with Jaime’s weirwood dream in which Cersei takes away the “only light in the world” and leaves him in darkness but then Brienne lights that darkness with her glowing blue sword - Oathkeeper - or maybe Lightbringer?)

Still, the parallels between Jaime’s being sent away from Brienne by Roose Bolton, and returning for her when she is in mortal danger and Jaime’s being sent away from Cersei by Cersei and refusing to return for her when she begs are completely intentional.
