What happened in ‘Dexter: New Blood’ Episode 4

In the latest episode of Dexter: New Blood, Dexter gets a call that Harrison was involved in an incident at school. He arrives to learn that Harrison stopped Ethan from shooting it up, suffering a knife wound in the scuffle.

While Harrison is hailed as a hero, Dexter questions his story due to a few inconsistencies, including with the blood spatter. Debra assures him that Harrison is not a killer, but Dexter becomes more skeptical the more he hears about the case.

Realizing Harrison would not have such a wound with the knife he claimed was used in the fight, he fishes around in Harrison’s belongings and discovers a blade similar to the one The Trinity Killer used to kill Rita Morgan. “He has my dark passenger,” Dexter says to himself, with a mixture of both worry and joy on his face.

Michael C. Hall on whether Harrison will learn the code in ‘Dexter: New Blood’

Hall, who plays the beloved serial killer, won’t outright say whether Dexter will teach Harrison the code, but he teased he could.

“I think that possibility is a part of the fun and the richness of that relationship,” he told TVLine. “There are opposing things that are happening simultaneously for Dexter when it comes to Harrison and the dark passenger. On one hand, it’s Dexter’s deepest fear that his son has the dark passenger, and on the other hand it’s his deepest wish, which makes parenting tricky.”

Showrunner Clyde Phillips also said Dexter is “curious” to find out how Harrison was impacted by the experience of seeing his mother get killed right in front of him.

“There’s a phenomenon called inherited trauma, and Dexter has it,” Phillips said. “He wonders if Harrison has it, too, or if he was too young to remember. And we’ll learn the truth of what that is. Obviously, it’s the more entertaining truth. If Harrison had nothing and no memory, then we have no story.”

Phillips also said that over time, Harrison will exhibit even more troubling behavior.

“We don’t know if it’s a dark passenger, but there is a darkness in Harrison that will emerge,” he added. “I’ll just leave it at that.”
