Aizawa is teaching his class when he notices they are usually silent. His eyes narrow as he knows there are no scheduled surprises. He is on high alert, in case it's a villain attack.

He follows their gazes and sees you hanging upside down from the vent by your capture weapon. Last he knew was that you were staying in America to finalize the requirements to transfer over to Japan.

Aizawa: Darling, what are you doing here?
