Patrick Dempsey has been cast in a regular role in Dexter prequel series, Original Sin.
The Grey's Anatomy star is set to play Aaron Spencer, the Captain of the Miami Metro Homicide department who has a decades-long relationship with Dexter's adoptive dad, Harry Morgan, portrayed by Christian Slater (via Deadline).
Dexter: Original Sin stars Patrick Gibson in the role of the young killer played by Michael C Hall in the main series. Rounding out the cast of Original Sin are Molly Brown, James Martinez, Christina Milian and Alex Shimizu.

The 10-episode series from showrunner Clyde Phillips follows Dexter in 1991 Miami as he struggles to keep his killing urges at bay and confides in Harry. His dad teaches him the Code he will later live by, teaching him how to kill those who deserve to die and managing to get away with it.
This proves especially challenging as Dexter begins a forensics internship at the Miami Metro Police Department.
What to Read Next
Dexter: Original Sin follows limited series Dexter: New Blood, which is also produced by Phillips and ends on a massive twist, with Dexter killed by his own son Harrison.

"We needed him to [die], I think," Phillips explained to Rotten Tomatoes at the time.
"Dexter is an antihero, which is [still] a hero that we like, but he is still psychotic. And he kills people, and you're not supposed to kill people.
"So it's, in a way, it's just desserts. In a way, it's what has to happen. And as for the specifics of the method of how it happened, that evolved in the writing room. We had great writers, and it's what we call 'best idea wins.'"
Dexter: Original Sin will air on Showtime in the US and Paramount+in the UK. Dexter and Dexter: New Blood are both available to stream on NOW.
