The rambling wasn't minded. Isabela was used to it happening sometimes when they talked. And in this present moment, the rambling seemed appropriate. "I do, what is that saying here, call it as I see it. To me you are Jaime, and what really matters is what you do here. The past's past and there's really no use dwelling on it because we can't do a bloody thing to change it. And really, all the bastards that judge you without even trying to get to know you aren't worth your time anyway." For being someone who pretended not to care about things, Isabela cared a great deal for a great many things, but select few people ever got to see that about her. Jaime had seen she upheld values and truly wasn't as shallow as she pretended to be. It was yet another way she had to protect herself from getting hurt. "If you ask me, it sounds like they make you swear so many vows that they begin to contradict themselves."
Oh she knew better than to ever voice her thoughts on Cersei, not to Jaime and certainly not anywhere he could overhear or read it. Really, Isabela just didn't even want to broach the subject if she didn't have to. She would go out of her way to ensure that she never crossed paths with Cersei. The last thing she needed was for Cersei to catch wind of her and Jaime and try to get rid of her. And Isabela had enough problems without worrying about Jaime's sister trying to kill her or bury her alive or something equally as unsavory.
Part of her didn't exactly like the fact she'd be the other woman, but it wouldn't be the first time such a thing happened. Isabela had been the other woman more than once in her own world. Of course the difference between those times and this one was that she was currently invested in the relationship. She was all ready tied to Jaime because of how she felt about him, though she wasn't admitting the true depth of such emotions just yet. But she wanted him, needed him, and right now she would take whatever she could get. As long as it could keep her from feeling like her heart was breaking on a daily basis, that would be fine with her.
Maker, his kiss always drove her wild. Such fire and passion. And even as she wanted him, wanted to be his, she broke the kiss after some moments, though she remained close to him, not wishing to pull back. "Just know that if you break my heart or are cruel to me again, I will cut off your balls." She looked him in the eye, a glint passing through them that was teasing in nature, though she was extremely serious. She felt this was a fair trade, really.
