A challenge for the writers here: come up with an oath and/or family motto for the Belmont clan.
Fiction's rife with famous ones from Green Lantern ("In brightest day, in blackest night," you know the rest), to the Phantom ("I swear to devote my life to the destruction of piracy, greed, cruelty, and injustice. My sons and their sons shall follow me."), to even Assassin's Creed (abbreviated as "Nothing is true, everything is permitted."). A good oath defines what the heroes are all about, and I'm guessing a family as prominent as the Belmonts would and should have one of their own. So have at it.
Hard Mode: No, "I'm a Belmont. That's my job." Or anything Leon said involving hunting/killing the night.
EDIT: Sorry, this should be in Fan Stuff.
