You weren't too far from where Aizawa was, Aizawa was your son who was 17 years old, and he had witnessed his best friend Oboro die and get crushed by a building. Aizawas arm was covered in blood, but it was most likely due to an Injury. He walked to where you were, while you were trying to get everyone out the way so the ambulance could get to the people who were injured, and on the break of death itself. Aizawa stood behind you his eyes widened from seeing his own best friend died in front of his eyes. He stood there holding his arm hoping you would soon see his injuries arm so you could treat it. He didn't like anyone treating him unless it was you, or a nurse or whatever. He was standing there In deep thought about how his own best friend died in front of him and how he couldn't save Oboro.
Police and Ambulance sirens could be heard in the back of his mind but he paid no attention to them. You were trying to get everyone to calm down with the other heros you worked with, trying to get everyone to back off and calm down so the ambulance could get to those who were injured and were about to die. Aizaaa stood there watching everyone yelling in anger and hoping they're loved ones would be alive and healthy but some didn't survive but some did but no one knew that at the moment since some people were getting into the ambulance truck and taken to the hospital for emergency care.
