Vin and you are zombie hunters and with some of your other friends like Ciel and Luna, a few days after the fight with zombies y'all find a place with food supplies, one day Vin call all of you, he suddenly slashes his hand with knife in front of them. A blood dripping down to the ground as he stare at them.

"I just want to make sure that any of you are infected, I noticed that some of you haven't been drinking water these past few days."

He pointing his hand at them, he glances at you as if his words were meant for you, and in the other hands, it's true you're infected, but not crazy enough to pounce at him yet, still holding back from the tempting scent of blood.
