Most of what he says is true; Pepper is aware that the encounters that have happened have been coincidences rather than planned engagements. Yet she still sees logic in making the demand, particularly as Loki himself points out how helpless they might seem to be if they had to stand against him. So when he gestures, indicating that she's been free to abandon this conversation, she arches an eyebrow.

"That goes both ways. You didn't have to talk to me any more than I had to talk to you." If he truly is so powerful, then Loki possesses the ability to disengage from the various conversations he's referred to. Certainly Pepper couldn't hold him here if he didn't wish to be.

But what he says next does catch her interest. Certainly Wonderland isn't a pleasant place to be, yet in their world Loki is supposedly dead. She wants to ask, to point out just what he's supposedly wished for, but she thinks better of it. "I'm not going to presume to know your motivations, especially considering that you thought trying to conquer the world was a good idea. I wanted to be very clear on the fact that trying to harm the people here doesn't help you--especially if what you just said is true."
