Well, someone seems easier to get a reaction out of than she expected. Should she antagonise the man currently trapping her in some kind of computer hell? Probably not. Is she going to? Absolutely.

But something about the next part worries her. Seen it before makes her wonder about Raine. And Hunter. She does her best not to make her response obvious, but she doesn't necessarily succeed. She wants to ask, but she doesn't want to give him the satisfaction of making her worry. So first, she leans into continuing to be obnoxious.

"You only 'stuck in my mind' because I was figuring out what you were up to before you just went and told Nia. Wish you'd done that a little earlier, woulda saved me some dreadful boredom." She shrugs, taking a moment before she goes on.

"Anyway. You don't just know what it is? I would've expected you to have a better handle on the stuff going on in here. Or do you only see what we feel like showing you?"

The phrasing is somewhat of a bluff—she wasn't expecting him to show up in her dream(?) at all, but now she's trying to figure out exactly how much the guy is actually in her head.
