I'm trying to think what threw me off here. I think it's the fact that they're discussing the chances of Paige spying on them again. That is, how it affects them. I'd have expected them to discuss how it would affect Paige.
I'm not saying they planned it - I realize that they didn't. But if they had planned it, I could see them reacting this way.
