At Ricardos nightclub, Mike meets with Sondras other brother, Bruno Rodrigo Santoro, and learns that Joe quit as the clubs bouncer because Bruno never paid him. Mike confronts Bruno about the situation but is rebuffed. Mike then declines Brunos offer to fight on the undercard of an upcoming match between Ricardo and Japanese legend Morisaki Enson Inoue, which could potentially pay out 50,000. Mike believes competitions with money as the incentive are not honorable and weaken the fighter.Meanwhile, aging Hollywood action star Chet Frank Tim Allen enters the nightclub without security and is accosted by a man with a broken bottle. Mike intervenes and subdues three men in the process. The following day, Mike receives an expensive watch and an invitation to dinner from Chet.
