Viewers never meet Harry Morgan when he's alive.

This is Dexter's foster father, who adopted the boy after his mother was murdered as part of a failed drug bust. Harry is often seen in Dexter's flashbacks, as we learn the lessons that he tried to impart on his son in order to assist him with his rage and murderous tendencies.

We also learn that Harry was actually having an affair with Dexter's mother - a criminal informant - at the time of her slaying. He killed himself once he saw just how far over the edge Dexter really was when it came to ritual killings.

Dexter Quotes

I love Halloween. The one time of year when everyone wears a mask... not just me. People think it's fun to pretend you're a monster. Me, I spend my life pretending I'm not. Brother, friend, boyfriend - All part of my costume collection. Some people might call me a fraud. Let's see if it will fit. I prefer to think of myself as a master of disguise.

Tonight's the night. And it's going to happen again, and again. It has to happen. Nice night.
