I'm RP-ing Vincent on facebook and one vampire joke too many led to me posting a status saying "let me put the vampire jokes to rest once and for all." And explained that Hojo put Vince in the coffin and he stayed cuz he felt he deserved it. The red wine is not because it looks like blood but because he and Lucrecia had red wine on their picnic. Late nights are due to nightmares. The only time he has fangs is when he transforms into Galian Beast or Chaos.
There was also a conversation that went like this:
them: are you a vampire?
them: there are a lot of clues to suggest you are
Vince: there were a lot of "clues" suggesting that the world would end last year, that didn't make it true.
I've been told by someone that my Vincent page is the most honest one that they've come across
