As the couple leave the building, Janey-E tells Cooper that she settled the gambling debt, and notes that they will be using his jackpot money for Sonny Jim. Ike "the Spike" suddenly approaches them with a gun drawn. Cooper immediately springs into action, grabbing Ike's arm and sending it to the ground, where it harmlessly fires off a shot into the pavement. He then karate chops Ike's neck while Janey-E chokes the would-be assassin. The evolution of the arm appears to Cooper, insisting that he "squeeze [Ike's] hand off!" Cooper ends up squeezing Ike's hand so much a piece of skin becomes stuck to the gun, before with another karate chop Ike painfully retreats. Various witnesses are interviewed about the incident, all expressing disbelief at Dougie Jones' actions. A forensic investigator removes the piece of Ike's skin from the gun.
