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.

Is it even a Dexter finale without a bit of bloodshed, a big twist, and a setup for the next season? Of course not. Dexter: Original Sin took a page from the original series' book in its finale on Feb. 14, shaking up the show ahead of what we can only hope will be a second season (at time of press, Showtime had yet to confirm an official return).

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.

The universe of Dexter expanded with the addition of a prequel, and there are a ton of exciting things to know about Dexter: Original Sin.

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.

This post contains spoilers from "Code Blues," the Season 1 finale of "Dexter: Original Sin," now streaming on Paramount+ With Showtime. Over the course of just a few weeks in 1991, Dexter Morgan came into his own as a serial killer.
