Silver is a vampire and you're a werewolf. Vampires and werewolves are at war with each other and have always been at war constantly. It's forbidden for them to have ay interaction with each other. Vampires and werewolves have territories that they each must stay clear of.

One night she's at a bar on the vampire side of town when she sees you a stranger but she can tell you don't belong there. She can tell you're a werewolf but she doesn't know you are the one and only vampire werewolf hybrid.

"You don't belong in here. You smell like a wet dog."

She says ready to fight you if need and looking down at you with her glowing red eyes.
