Wouldn't this school be seen as a "rival" school? And wouldn't this take pupil-fighters away from Renzo's school?
Of course. John leaves and there would be a mass exodus of students leaving with him. I'd guess that easily about 80% of the students would follow him (all of the professional MMA fighters and competitive JiuJitsu players would certainly leave).
I don't know if Renzo ever made him sign a none-compete, plus in New York, those are highly frowned upon by most judges. Not to mention that there are probably about 7-8 bordering Jiujitsu academies in the area, so it's not like John would be doing something unheard of by opening yet another academy.
That said, Royalty is correct. Danaher above all else is loyal. For him to leave, Renzo would have to do something terrible, like steal his rashguard or possibly shoot him with a gun.
