Investigating Zach's murder, Dexter finds DNA evidence and learns that the Brain Surgeon is Vogel's psychopathic son, who faked his own death years ago and changed his identity to that of a dead man, Oliver Saxon. U.S. Marshal Max Clayton (Kenny Johnson) arrives in Miami to search for Hannah, but Dexter throws him off the trail and moves Hannah to Deb's house. Deb suspects Saxon of Cassie's murder, but he goes into hiding. Debra later considers rejoining Miami Metro. Dexter lures Saxon from hiding but loses him, after which Vogel implores Dexter to let this case go. Dexter makes plans to leave Miami permanently, taking Hannah and Harrison with him, but not before finding and killing Saxon. Unbeknownst to Dexter, Saxon has reunited with Vogel, who accepts him into her home.
