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).

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.
