He takes it all in without saying a word, one hand to his mouth and a finger sometimes tapping against his upper lip. He takes note of anything that might be useful - which includes everyone else in the vicinity and how they're acting, as well as all of the possible potential exits, not limited to silly things like doors.

Once the tour is completed, he bows slightly, and thanks the NPC Nurse Joy.

"Thank you. Yes, it was very helpful. I'll keep this all in mind."

And then he goes back to where he sees Yuuma's very... recognisable hairstyle. Hardly something one could miss or mistake, that.
