Original Sin ends with Deb (Molly Brown) deciding to forego a college volleyball scholarship to follow in her father and brother’s footsteps at Miami Metro, setting up the intricate web of lies Dexter must weave to keep his cop sister off his blood-soaked trail.

Patrick Gibson has revealed he would be interested in returning as Dexter in a second season of Original Sin if it gets picked up.

Showrunner Clyde Phillips, who is currently working on 'Dexter: Resurrection,' just set up another season of the prequel series with that ending: "We didn't know everything going in, and still don't."

After letting the police captain escape in Episode 9, we see Dexter (Patrick Gibson) follow Spencer to a massive ship, where he’s holding his son. Realizing that Dexter has caught up with him, Spencer floods the chamber where Nicky is chained, forcing the serial killer into a choice — save a child or let his urge to kill take priority.

Dexter: Original Sin actor Patrick Gibson sat down with ComicBook.com to discuss the entirety of the first season of the prequel series. Dexter is a show that is held highly among its fans and has only continued to add new fans since its debut almost 20 years ago.

Young Dexter Morgan will experience a “defining moment” during the season finale of Dexter: Original Sin, teases Patrick Gibson, adding that “something will shape him into the Dexter that fans know.” The Irish actor plays the titular character in the prequel series.
