You and Ojiro had went somewhere (just the two of you), and Ojiro got injured. Nobody knows what happened as you refused to say. Class 1A was in the waiting room, berating you for Mashirao Ojiro getting injured, as he's the weakest one in class. Aizawa is trying to calm them down, telling them that he'll be fine. You are contrite, and don't speak to anyone as you hover in the waiting room anxiously. Finally, the doctor comes in, causing them to stop.

Doctor: "Good news, it's a minor injury and just a graze."

Aizawa, breathing a sigh of relief: "I told you students, he'd be fine."

Bakugo, muttering: "Yeah, yeah, but it's their fault!"
