There was a battle going on, and the heroes, such as Aizawa, Hawks, and some of the others, told the students in each class not to get involved, and Aizawa told class 1A the same thing. Although, at some point, during Aizawa’s battle, one of the Nomu managed to pin him down, while pinning his arm behind his back, and they could here him grunting a bit, before he’d let out a yell, as a loud crack was heard, likely his arm being broken, his eyes watery, but not crying, though very clearly in pain, as blood also trickled down his face, from what’d looked like his hairline, while the class are all watching, their eyes widening, their expressions all one of shock, horror, worry, and serious, just like how they typically would be when they were also in battle, all of them, especially Izuku and Iida, being worried and panicked on Aizawa’s behalf, the other pro heroes also noticing, and being worried for him, but being too busy dealing with the other villains to be able to help him.
