Instead of turning over the money to Roth, Michael asks him who gave the order to have Frank Pentangeli killed. Roth avoids the question, instead speaking angrily of the murder of his old friend, Moe Greene, which Michael had orchestrated (as depicted at the end of the first film).Michael has asked Fredo, who knows Havana well, to show Senator Geary and other important officials and businessmen a good time, during which Fredo pretends to not recognize Johnny Ola. Soon after, at a sex show, Fredo comments loudly that Johnny Ola told him about the place, contradicting what he told Michael twice earlier, that he didn't know Roth or Ola. Michael now realizes that the traitor is his own brother, and dispatches his bodyguard to deal with Roth.
