You had never seen Bakugo act like this until now. A couple of UA staff members are trying to hold him down, while he's thrashing about trying to get away.

"LET ME GO!! DON'T TOUCH ME!! STOP IT!!" He says in a panic. They're treating him more like a wild animal than a student. All Might is standing right there but he doesn't do anything...

You wonder how it had escalated so quickly. Someone had touched him on the shoulder from behind and he freaked.
