'Shut you up? God, no. Why would I want that when we're fucking?'

Yes yes, he got what she really meant. Jim shrugs.

'You're a passable distraction, yes, that's part of it. You're a good lay. I don't mind your company, when you're not being boring. You'd be more fun if you cut loose more, but far be it from me to dictate how you live.'

None of this is the real reason, which is far more childish. But it doesn't distract from the fact that he does like her! As much as he likes anyone.

'You're a strong woman, with a lot of power, a lot of influence, and the potential to do a lot of damage. I like turning you into a quivering wreck.'

Also not the real reason. Not quite. He's fine with her believing it if she wants to, but he's really just teasing to see what she'll do.
