Vincent "Vince" Masuka is a fictional character in the Showtimetelevision seriesDexter and the novels by Jeff Lindsay upon which the series is based. On television he is portrayed by Korean American C. S. Lee. Masuka is the Miami Metro Police lead forensic science investigator; he works alongside Dexter Morgan in the lab and at crime scenes. He often cracks tasteless and inappropriate jokes, invokes his Japanese heritage only when convenient, and harbors unrequited desire for Dexter's foster sisterDebra. Although goofy and obsessed with sex, he is clever and very good at his job, causing Dexter to worry from time to time that Masuka will uncover his secret.
Character overview
He is portrayed as obsessed with sex — the kinkier the better — and is not shy about propositioning every woman he meets, although he is able to tone it down when the situation calls for it. Detective Joey Quinn once confronts him about his behavior, stating it is the reason that no-one likes to be around him. However, he seems to accept Joey′s explanation when no one comes to see his speech on his newly published work, for which he has cleaned up his act and dressed formally.. At Debra's request, he returns to his old self at the end of the episode, although his demeanor appears less vulgar. One of his saving graces is his sense of personal loyalty to his colleagues. He is greatly distraught after seeing Dexter's wife Rita kiss another man, and tries to tell Dexter.
Notable events
In the sixth season, he begins guiding around a group of interns, bringing them through the labs and to crime scenes. He is attracted to one of his female interns, but is forced to fire her when she steals a prosthetic forearm and hand, evidence from the Ice Truck Killer case, and sells it online. He replaces her with Louis Greene, a tech-savvy game designer who helps Masuka with database analysis. In the seventh season, however, he learns that Louis was the actual buyer of the stolen prosthesis when Dexter mails it back to Miami Metro with a letter of complaint. Masuka fires Louis on the spot. In the eighth season, he discovers he has a daughter, Niki, who was the result of a woman using one of his sperm donations. At first, Masuka suspects that Niki is using him for his money, and even has Debra look into her past. When he learns that she works in a topless sports bar, he gets her a job as a forensics assistant at Miami Metro, allowing them to work together and get to know each other better.
Differences from the novels
In both the television series and the novels, Vince is socially and emotionally awkward. In the novels, Dexter views him as a kindred spirit, believing that Masuka is also "pretending to be human", and asks him to serve as the best man at his wedding. In Dearly Devoted Dexter, Vince throws a large bachelor party for Dexter within a few hours of finding out about his engagement, and in Dexter in the Dark takes his role as best man so seriously that he calls in favors to hire Manny Borque, a famous caterer, for Dexter's wedding. In the novels, Dexter feels a kinship with Masuka; he senses that Masuka is also hiding who he truly is. As in the television series, Masuka sets up Dexter's bachelor party and kidnaps him to get him there.
