Michael suspects Roth planned the assassination, but feigns ignorance when they meet. In New York City, Pentangeli attempts to maintain Michael's pretense by making peace with the Rosato family but they try to kill him. Roth, Michael, and several of their partners travel to Havana to discuss their future Cuban business prospects under the cooperative government of Fulgencio Batista. Michael becomes reluctant after reconsidering the viability of the ongoing Cuban Revolution. On New Year's Eve, Fredo inadvertently reveals that he knows Roth's right-hand man, Johnny Ola, having previously claimed that they had never met, and Michael realizes that it was Fredo who had betrayed him. Michael orders his bodyguard to kill Ola and Roth, but the bodyguard is killed by the police as he is attempting to assassinate Roth with a pillow in his hospital bed. Batista abdicates due to rebel advances. During the ensuing chaos, Michael, Fredo, and Roth separately escape to the United States. Back home, Michael learns that his wife Kay has miscarried.
