Runaway (Dexter: New Blood)

Dexter (Michael C. Hall) is still stunned at finding the straight razor, telling Debra (Jennifer Carpenter) that he needs to help Harrison (Jack Alcott) in this difficult time. Meanwhile, Kurt (Clancy Brown) leads Chloe (Skyler Wright) to the bunker, telling her she can stay for as long as she wants.

When Dexter questions Harrison about the razor, he claims he uses it for defense. Angry at his father's lack of trust on him, Harrison storms off. Outside, Zach (Oscar Wahlberg) and his friends invite Harrison to a party, which he accepts. The partygoers were all part of Ethan's "kill list" and Harrison is the guest of honor. Harrison consumes ecstasy and oxycodone laced with fentanyl, and makes a minor slice on a girl's foot. He then shares with Audrey (Johnny Sequoyah) about his father, saying that he is lying about his name before passing out. Audrey is forced to call authorities and Sergeant Logan (Alano Miller) helps him regain consciousness and he is taken to the hospital. Logan informs Dexter about the incident and that the drugs were sourced from a dealer named Miles (Dakota Lustick). After Harrison is released, Dexter tells him he will go to therapy and he will limit his time out of the house.

Angela (Julia Jones) is informed that Matt has been staying at a luxury hotel in New York City after tracking his credit cards. She decides to go to New York to talk to him, as well as to attend a Missing Persons conference. She also allows Molly (Jamie Chung) to accompany her, as she needs material for her podcast. At the New York hotel, they are informed that Matt checked out of the hotel the day before their arrival. As they await security footage, they attend the conference, which is headlined by Angel Batista (David Zayas), who is now Captain of Homicide of the Miami Metro Police Department. She talks with Angel after the conference, where he briefly talks about the Bay Harbor Butcher and Trinity Killer, mentioning Debra's name but stating she died, along with her brother, Dexter, although he does not say his name. He also mentions that her brother had a son named Harrison.

Dexter retrieves medicines and equipment from a local veterinarian, planning to kill Miles. He arrives at the bar he frequents, acting as an interested customer. Outside, Dexter injects Miles but before he can fully inject him with ketamine, Logan arrives. Dexter then starts brutally attacking Miles until Logan restrains him. Miles is arrested but Dexter is also brought to the station for paperwork. Dexter witnesses Logan intimidate Miles with threats to charge him with homicide, and he confesses that he works for a man named Jasper Hodge (Kellan Rhude), who makes the pills. Dexter overhears the conversation and infiltrates Jasper's house to sedate him before the police will arrive in a few days with a warrant.

At the bunker, Chloe immediately sees the camera turning on and realizes her state. However, she provokes Kurt by undressing herself in front of the camera and refusing to go outside when he orders her. This forces Kurt to go into her room, where she uses a shard of glass to slice his face through his ski mask. He takes her outside, telling her to run but she refuses. When she approaches him, he kills her by shooting her in the eye, upsetting him. Meanwhile, Dexter prepares to kill Jasper in his home, having arranged his table, when he notices that Logan is outside. Dexter then removes all of his equipment and forces Jasper to snort pure fentanyl powder, which he had been using to manufacture adulterated fake Roxicodone, or "Blues". When authorities enter the house, Dexter and his equipment are gone and Jasper in found dead from an overdose in his chair.

Kurt picks up Harrison, who was planning on leaving town, and takes him to the diner. After some talk, he gives him a job at the diner. Harrison returns to the cabin, lying to Dexter about attending therapy. Angela and Molly are shown security footage of Matt checking out of the hotel, confirming that the person is not Matt and that Kurt lied to them. When she returns home, she talks with Audrey, who recalls Harrison's statement that his father wasn't Jim Lindsay. This prompts Angela to investigate based on her talk with Angel, finding something that shocks her. She then prints out its content, which is revealed to be an obituary for Dexter.
