"Would that Jaime had come with me, she thought… but he was a knight of the Kingsguard, his rightful place was with his king. Besides, it was Renly that she wanted."
George R.R. Martin, A Feast For Crows
SURE BRINNE SURE.
My favorite part is that this is not an inherently romantic (or sexual) thought. She wonders if she should have stayed with the men from before since they seemed honest, and then wishes Jaime would have been with her. It could easily have been just that she trusts Jaime, and that she knows Jaime respects her.
But then she tells herself no, she wants Renly, not Jaime.
Renly has nothing to do with this.
Renly never protected her. It was her job to protect him. And it wasn’t Renly that stopped the game his men played with her. Renly gave no indication he cared about her safety.
The only way Renly comes into this at all is if she wants Jaime there for reasons other than him helping her stay safe.
