Yeah, that was what I was thinking. At least Kurama can see that its running deeper than just what's going on in public, and it's a drastic change from who she was days ago. The talk at dinner featuring a more confrontational Botan could yield more insight. And as we know, Kurama is NOT dumb, so he's going to figure out that she is being influenced. Just as he does, boom, evil student, yadayada exposition, save Botan, free her from control.
