Rez the Manager, Is He a Manager?

In the movie his name is rez gaveron, and in real life his name is raffy gaveron. There's an insidious nature to this guy. I think with a right actor, i would have baught it. When he finally confronts cooper t and the moviand hes like, you're ruining her career and take her down with you. It feels a little, felt a little inauthentic to me.
