I don't really understand how this imaginary third-party killer is supposed to work in any practical way, but Statham's on my radar anyway, so...
The references to past games and alluding to sketchy roles isn't helpful. At least not to me. If you can give more info than you're giving, please do so. The vague references and self-asured attitude as to what's going on helps only you if you don't actually share anything. And I don't know why you wouldn't want the rest of us to be in the know.
