Emotional huh?

Ojiro gives him a rundown on the dude's quirk. Deku then spends an hr or so thinking about how to deal with this (as Deku does).

The guy then shits on your friend, and the first thing you do is speak? You had one job.

That's like.. cerebrum-can't-suppress-your-midbrain emotional. I call that being a dumbfuck, and it isn't Deku. Bakugo maybe.
