Well I guess I really am alone on this then.
So since if everyone believes that Trevor is Alucard, what does that mean for Simon? If Trevor became a vampire, That mean's that Simon will die in Mirror of Fate. And the Belmont clan, (who are still hunting Dracula in Lords of Shadow 2) will be non existant.
Wait a minute, what if it's not the Belmont clan, maybe it's another clan who replaced them:
The Morris Family! Ok im convinced now, I now believe with all of you that the Belmont clan are vampires and that the Vampire Killer will fall into the hands of their once rival clan. Get ready for the return of Jonathan Morris and Charlotte tag teaming against Zobek and Dracula at the end!
In the end, crow will be served and a victor will be crowned.
