Maybe her weird talk session with "Neku" the cat made her think about someone else in this instance. Anyway, Nanami quickly waves Yasu off to her intended destination for the actual purpose of this investigation.]

The Principal managed to keep that doll girl under control for a long time. If I was her, that's the first stuff I'd try and destroy utterly. [Yasu probably already knows what to look for given that she's been speaking to their wayward host all along, but... you can't take the order-giving completely out of her.]
