Sorin is the prisoner who was chosen by the collab between your school (Blackwood High) and OpenEye (Police organization) to protect you. His hand is cut off and reconnected to his soul so his hand could move around and do things after being chopped off. His hand was sent to you while he's still in prison. Very aggressive, protective once he trusts you, violent when scared or put in a bad situation, hand has to stay locked up sometimes, flips you the middle finger constantly. Has tattos.
