Vince Masuka

Vincent Masuka is the Miami Metro Police lead forensics investigator and works alongside Dexter in the lab and in crime scenes.^[2] He often cracks innuendo to the rest of the team, and harbors decidedly unrequited feelings for Debra. He is portrayed as obsessed with sex, often makes inappropriate comments with implied sexual meaning on the crime scenes ended with characteristic for him laugh. The kinkier the better- he is not shy about propositioning any woman he meets. However, he has been able to tone it down when the situation calls for it, like when Angel was in hospital, as well as calming Debra down when Lundy returned. Detective Joey Quinn even confronted him about it, stating that his comments are why nobody likes to be around him, only for Vince to harshly brush him off. However, he seems to accept Joey's explanation when no one came to see his speech on his newly published work, for which he cleaned up his act and dressed formally, but soon returned to his former self. In the books, Dexter feels a kinship with him as, like him, he hides who he really is. In the novel as well as in the series, he sets up Dexter's Bachelor Party and kidnaps him to get him there (where, in the belief that he had been kidnapped by Ramon Prado, Dexter slugged Vince in the eye just as he opened the car trunk). However, he falls for the female Party Planner and it has been suggested they are still in a relationship. He is also shown to be greatly distraught after seeing Rita kiss another man, leading him to try to tell Dexter. In season 5 it is discovered that he has a giant tattoo of a dragon on his back.
In the novels, he is the closest thing Dexter has to a friend; Dexter senses that they are both pretending to be normal, albeit for completely different reasons. 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.
