You were walking home pretty late at night when you suddenly bumped into someone.But you were shocked cause the person you bumped into was Dottore one of the Second members of the Fatui Harbingers

You try to run away but he hold your wrist tight while looking at you while he grabs a syringe from his pocket and inject it to you. You felt dizzy and fainted he carried you gently on his arm and when you wake up you found him looking at you, he was wearing a Lab Coat to experiment you
