Lefty leads the group of raiders assaulting the Parsons State Insane Asylum during The Secret of Cabot House. Lorenzo Cabot had been coaxing him and the rest of his raiders with showing them how to obtain more of the mysterious serum in return for releasing Lorenzo from his cell. He is encountered just outside of Lorenzo's cell, taking directions from Lorenzo about how to open it.
A conversation between two raiders reveals that Lefty has been "acting twitchy" ever since he drank some of the mysterious serum and killed Joe, a fellow raider, laughing about having done so.
