Jaime wasn't sure if he was supposed to be offended or not by being called an idiot. Trish, for that was what she was insisting he call her, had rolled her eyes and proclaimed she really would help him as she'd given her word to. And a motto to rival that of the Lannisters. Interesting woman he'd found. Jaime nodded just once allowing the smile that disarmed so many to return. "And I could hardly deny you your oaths if they are of such importance to you. Thank you once again." he said, waiting for her to lead them both to her room and begin the task.
When she offered to pretend she didn't know about him though he laughed, if she knew about Aerys then she probably knew about Bran Stark, maybe even about Cersei but that was a truth he held close to his heart and would for as long as he had to. Oh if he could he'd shout his love for her from every corner of the seven kingdoms themselves, from the Wall to Dorne there would be no denying his children any longer. Or his love for his Cersei. But that day was not this one. And even here he would not go against the wishes of his sister. They were not Targaryens, the Lannisters did not intermarry like that. It could never happen for them as it had for centuries of dragons. "I'm not sure how you'd pretend that though." he finally said, he felt like he'd drifted off for a time but so had she from what he could fathom. There may have been ghosts in her past just the same.
He wanted her to just say it, there was nothing she could say that would upset him. He regretted the Stark boy having to wind up a cripple but he'd had to save himself and his sister. He'd have killed him a dozen times over just to save Cersei any hurt. It was probably something he ought to be ashamed of, other men would. But Jaime Lannister was not like other men. "I'm not ashamed of my past." he told Trish. "There have been regrettable actions yes and I will answer for any of them you wish to query but do not just brush it away. You know the name Kingslayer but you spoke it without the immediate revulsion I tend to hear from any Westrosi who might dare to repeat it in earshot of me? Why is that? And how do you come to know it? What else do you know of me?"
The cloak of the Kingsguard would keep awhile. At least until Jaime knew the whole story of how this woman knew his history.
