☠ —- for how i think my muse would die
Oh hahaha you want my pain do you. So you see, by AFFC/ADWD we know Cersei is on a bad path and gets more and more revengeful and less and less rational. Her mental health is deteriorating, her paranoia growing stronger and after the walk of shame she has hallucinations and heavy trauma added on top of all that. The Cersei Kevan sees is faking. She is waiting for her time, for her revenge, and we know she's getting it bc no way Margy is winning that trial with Robert Strong around.
There are two people we can parallel her with at this point, the most obvious is heavily suggested in the text : "Now you sound like Aerys", yes, Aerys, suggested by both Jaime and the act of burning the tower of the Hand because Tyrion might be in it !
Secondly, we have the prophecy which says she will die by the hand of the valonqar, and if she is persuaded it is Tyrion, we know better. She is, after all, older than Jaime.
How fucking ironic would it be if Jaime has to kill her like he had to kill Aerys ? We know what losing Joffrey did to Cersei, losing Tommen and Myrcella will only make that worse. But she won't go without a bang, she is destructive and revengeful and would take down everyone with her, everyone who dare hurt her and her kids and who cares if it means innocent people too ? She is like wildfire after all.
Jaime had to kill Aerys because he was about to do something terrible, and again he will have to kill Cersei to stop her from doing something incredibly destructive and reckless -- now I'm pretty sure he wouldn't survive it either. It would be for her sake (a bit of mercy in this too, maybe ?) and for the innocent lives but he will never live with this, well he is not likely to ç_ç
so tldr Jaime is the valonqar -- will probably kill her like he killed Aerys to stop her from doing something terrible, driven by paranoia and anger and revengeful thoughts
❦ —- for a controversial thought/idea/theory
I headcanon Cersei as trans. She still partially identify as a woman so I lean on non binary but from childhood there was obvious dysphoria in the text -- of course a lot stems from mysogyny and how awful she feels about the way society treated her but I definitely think there is something more.
