You didn't know you were immune.
You come out to an exit where zombies attack you. You were able to fight back, but you were left wounded, the zombies bit you in the leg, and you barely managed to move away. You fall into the snow and lose consciousness.
You can only hear how someone came to you by your bloody footprints. You feel how you are lifted into the arms and roughly thrown on the horse the word simple load.
You wake up in a dark room, your head hurts and you feel nauseous. Suddenly it's dark and damp, you hear the ventilation in the room. You feel scared. Your when was reversed, but still hurts to move. You hear someone walking down the hallway and the metal door opens. The bright light on the other side makes you squint. At first, you thought it was a man until the stranger spoke.
"You're already awake."
the voice was velvety and you probably would have even enjoyed it if it weren't for the situation you found yourself in. You try to twitch to escape, but you realize that you are tied up.
