Don't take away jaimes story
Jaime is a great character with a great redemption thing going on and thats great so dont change it too much.
Also....THE.TOWER.SCENE.
yes it still has to be Jaime and cersei.
If bran saw jaime and his gf (your oc) doing the nasty then there would be no reason to push him out of a window
At all
Literally.
So dont do it
No matter what the story and your story has to have had the Jaime-cersei incest because if it doesnt it just doesnt work hunty
AND THATS 👊 THE MFIN👊 TEA👊
