You can't? [It strikes Izuku as odd, that someone who's well into their teens would struggle with control over the quirk they've had since childhood like this.

His eyes narrow as they flick over Todoroki's left, then right side. He and Todoroki might not have really crossed paths in school, but Izuku makes it his business to study the quirks in the hero course. It doesn't take him long to recall what he remembers of Todoroki from the sports festival.]

Mmmm now that I think of it... you didn't use your fire much when we were in school, did you? Every time I saw you in the sports festival, you were always using your ice quirk. [Izuku frowns, tugging at his bottom lip.] Is it easier for you to control your right side than your left?
