( May 2026 ) ( Learn how and when to remove this message ) Six months after killing LaGuerta, a shattered and guilt-ridden Debra has quit her job at Miami Metro and joined a private investigation company, run by Jacob Elway ( Sean Patrick Flannery ). Deb abuses prescription medications and even cocaine while working undercover to bring in Andrew Briggs ( Rhys Coiro ), who has stolen jewels from the mob. In LaGuerta's absence, Batista has returned from retirement and become Lieutenant. Miami Metro investigates a new serial killer, the "Brain Surgeon", who takes melon ball size scoops of brain tissue from his victims. The MMPD receives help from psychopath expert Evelyn Vogel ( Charlotte Rampling ), who also appears to have a keen interest in Dexter. Dexter tracks down Debra and asks her why she's been avoiding him. Debra tells Dexter she hates herself because of him. Dexter starts to spiral out of control, choking someone in road rage. Quinn and Jamie have begun a relationship, which Quinn wants to keep secret from Batista. Dexter tracks down Debra again and says Briggs is being targeted by El Sapo, a mob hitman, but she doesn't care. Briggs returns and Dexter and Briggs fight, with Dexter stabbing Briggs to death with a nearby knife. Debra throws out Dexter and calls police. She finds a safe deposit key on Briggs' keychain that could lead to the stolen jewels, which have a recovery reward that would partially go to Debra. Debra doesn't notice El Sapo following her from the crime scene. Vogel confronts Dexter with murderous drawings from his childhood, and reveals that she knows about Harry's Code.
