Well as I went back to the other thread to read up on Vincent's exact timeline, he only became Evil once he had been possessed by the chaos monster and kept as a slave for 5 years. 

So not so much a chance as off yet. This Alysis is actually more scary. Since the time line has been moved, Nicola(Or based William) and Trip can appear as students also.

And Update how do you mean? I can write a response if you like.
