Jennifer Carpenter to Return for ‘Dexter’ Revival Lesley Goldberg Jennifer Carpenter will return for Showtime’s Dexterrevival, sources confirm to The Hollywood Reporter. The actress played Dexter Morgan’s sister for all eight seasons of the original Showtime series. The character was famously killed off in the 2013 series finale. (Showtime declined comment.) Carpenter, who was adamant about wanting Deb to be killed off, left the door open to returning to Dexter in a series finale postmortem with THR. “[It would take] an extraordinary script many, many, many years from now,” she said with a laugh. “I don’t know if that’s possible because people don’t come back from the dead.”
