This video starts with the teacher’s effort to de-escalate the situation. The teacher, soon-to-be-victim, tries to get his charges to settle down and act right by getting between them, but unfortunately that didnt work
Immediately after being knocked down and possibly unconscious for a moment–possibly just hard in the dome–the teacher regains motor control and settles into a casual 50/50 as a way to keep his student from getting into a bloody battle. Fortunately, someone else steps in and holds back the other fighter in the altercation.
