Well, Mia will suggest he learn a bit more about his EMOTION LASER because it is not like his power will just go away without thinking about it. She will set it up so he has privacy from his classmates but suggest he learns what triggers his powers to better know how not to trigger them.

She will also suggest he find Houshou, and talk to him if he would like to speak with a teacher that has more experience/understanding of this sort of power.
