## Plot

At a retirement home, the residents are playing bingo. A woman, Barbara (Kathleen Rose Perkins), is joined by a young man (Roby Attal), who helps her with her card and bonds with her. As she introduces herself, he reveals his name is Brian. When Brian wins the game, he invites her to dine with him. He reveals his full name as Brian Moser and sedates her, taking her in his van.
At the hospital, Harry (Christian Slater) is informed about Bobby's condition. LaGuerta (Christina Milian) confronts Harry for stealing the file from Tampa's police, and he finally comes clean about Brian's status, but asks her not to interfere. Nevertheless, LaGuerta visits Camilla (Sarah Kinsey) to check Estrada's file, which she complies, informing Harry that she omitted Dexter's name from all files.
Dexter (Patrick Gibson) wants to continue his plan to kill Spencer (Patrick Dempsey). He breaks into his apartment to sedate him, but is forced to leave when Spencer arrives accompanied with Harry. The following day, Dexter's investigation into Nicky's status is interrupted when Tanya (Sarah Michelle Gellar) assigns him to take care of a blood drive for Bobby. Spencer is one of the volunteers, and he and Dexter have a tense conversation over Nicky's disappearance. Clark (Aaron Jennings) also wants to donate, but confides in Dexter that he had contact with a man who tested for HIV and is awaiting results to know if he is positive as well, so Dexter agrees to donate blood in Clark's name. Dexter is also forced by Masuka (Alex Shimizu) to donate more blood in his name. Returning home from donating blood, Debra (Molly Brown) receives a voice mail from Florida State University; despite her school incident, the volleyball team is still interested in her.
In flashbacks, Harry convinces Spencer in leading a search party for Laura (Brittany Allen) and the kids, but is demoted after revealing his affair. After some time in checking the shipyard, the police finally find Dexter and Brian, along with Laura's dismembered body. As custody services do not want to separate the brothers and as their father is in prison and having renounced his parental rights, Harry and Doris (Jasper Lewis) agree to act as foster parents for Dexter and Brian. However, Brian almost smothers a young Debra when she does not stop crying, and attacks Harry when he scolds him, breaking a window in the process. Harry and Doris decide to send Brian away with a Custody Services worker, Barbara, but keep Dexter as they grew attached to him.
While investigating the murders, Harry is shocked to realize that Brian was present in each of the crime scenes. He visits an unconscious Bobby (Reno Wilson) at the hospital, confiding in him that Brian returned and his concerns regarding Dexter knowing about it. Bobby briefly regains consciousness to say "Save Dexter". That night, Spencer returns home and finds a note where someone demands money or he will expose his ruse, and he takes a gun to the meeting location, an arcade Nicky frequented. Dexter attacks him and despite initial resistance, he manages to sedate Spencer. When he wakes up at the killing table, Spencer admits to using Nicky to get back at his ex-wife for cheating on him, as she turned their son against him. Dexter begins torturing Spencer to reveal Nicky's location, and leaves him alone to consider his decision. However, Dexter accidentally rips part of the wrap, and Spencer releases himself. He leaves in his car, unaware that Dexter is following, having set it up to find Nicky's location. At an undisclosed location, Brian ties Barbara to a pole, scolding her for separating him from Dexter. He takes a chainsaw and starts dismembering her.

## Reception

"Blood Drive" received positive reviews from critics. Louis Peitzman of Vulture gave the episode a 3 star rating out of 5 and wrote, "The penultimate hour of this series' first season probably could have been the finale, but instead the show is treading water, a frustrating move after last week's propulsive episode. On the other hand, an explosive finale could paper over a lot of Original Sin's, well, sins."
Callum Murray of Game Rant wrote, "These scenes shed more light on the events in the 90s timeline, and they generally work really well. It still feels very fan service heavy to introduce Brian Moser into the story, with legacy fans very aware of what eventually happens to him. However, Roby Attal nails the character, and it's fun to see his origin story."
Greg MacArthur of Screen Rant wrote, "After Spenser admits to kidnapping Nicky but not to being a serial killer, Dexter is taken aback by the apparent lesson that one major life event can turn a good person into a killer. Still, a lot of explanation is needed to call Spencer a good-to-great Dexter villain after Original Sin episode 9, and these details will have to be sorted out in the season 1 finale." Mads Misasi of Telltale TV gave the episode a 4.5 star rating out of 5 and wrote, "For a season that's already been packed with well-timed reveals and intense sequences, the penultimate episode, Dexter: Original Sin Season 1 Episode 9, “Blood Drive,” still manages to pack a punch."
