The rest of the lesson was spent without any problems. At least for Ashton. Amaira was pissed because well, she wanted to teach the mutt a lesson. Instead, it was her who was taught a lesson by the director.
Not because she was targeting but because of how terrible Hugo's condition was. Even with magic, it would take him a couple of weeks to get back to his feet and that too on his first day in the academy.
Also, the Del Rio family was angry but they could not blame Ashton as he had not broken any rules. He just did what they were told to and fought their son. As a result, all of it was blamed upon the professor for not stepping in sooner during the duel.
Amaira might have been pissed, but something good came out of it. The student of his year got to know it wasn't a good idea to mess with him directly. As once Ashton stopped holding himself back, there wasn't much they could have done to stop him.
