So, all we know from the game is that Vanessa and Vanny are eerily similar, and you might think Vanessa IS Vanny, but the game tells us wrong. In the V.I.P./Fire Escape ending, we can see Gregory taking off Vannys mask, and it's Vanessa wearing it, except she isn't an antagonist, because you cam see that she is sad of what happened to Freddy, and all the other Animatronics. I hope this told you a little bit about who Vanny and Vanessa are.
