Boss Kaplan was a crimelord in the Matrix. He loved the opera.
He waited for them in the room they entered and were surprised to see him standing there. Jimmy tried to excuse himself to not get the "wrong" idea, while Carlos was so nervous that he kept aiming on him. Then started shooting Kaplan's henchman, only to be shot back.
Tony and Jimmy split, and Kaplan ordered Carmine to find Jimmy and shoot him in the head, however Jimmy jumped through a window and ran away.
