Reigns can happily tell Vince to fuck off if he wants to, get some good press for doing so then call up Tony Khan, Gedo or The Rock depending on what he wants to do next in his life. Even if Vince is privately pissed, I don't think he'll do much about it. They're throwing buckets of money at people he doesn't even give a fuck about like The Revival just because they don't want anyone to jump.
