With Dexter gone, Quinn turns to Deb and says that Dex is a kind of a dweeb. She tells him that if he says another word about her brother, she will kick his balls down his throat. He points out that she's not making sense, so she changes the subject. Um, so Anton doesn't have any prior arrests on record. And, he's paid in cash and is not in the CI database. She asks Quinn what he's hiding. Apparently, he didn't want to fill out the paperwork to process Anton, so he just pays him out of pocket. He pulls her to the side to tell her the story. She's incensed. She points out that he has put his life at risk for them and he had no legal obligation to do so. And, since there's no record, there's no end date for his service. They can string him along forever. He wonders why she's so upset and her face reveals to him that they're involved. He tells her it's really stupid to get involved with an informant, but she says it's also stupid to make the department liable for the tons of damages that Anton could claim in a lawsuit. Anton will never know if Deb doesn't tell him, but she says that "of course" she's going to tell him. He asks if she would sell out a cop for some dope she was fucking. His tactics are odd. Yeah, insult her; that will get you what you want. She says that what she's doing is no worse than your laziness being responsible for another cop's death. She tells him that Yuki told her, then walks away. He is stunned, but barks back, "You don't know what the FUCK you're talking about!"
Dex and Miguel are parked in a car across the street from Billy Fleeter's house. We see Billy get into his car and drive away. They're sneaking in the back as Dexter VO's that if he's going to stop this, he's going to have to do it soon. He reminds Miguel that they are committing a breaking and entering. He doesn't care. Dex gives Miguel latex gloves to put on. Miguel chuckles and says that no one would ever question why a forensics expert is carrying latex gloves. Dexter breaks into the back door of Billy's home, but makes it look like it was hard for him to do. Once in, Dexter says that they are looking for proof that Billy is guilty. Dexter says that they know that Billy bludgeons people to death, so they should look for something "bludgeony." How Pee-Wee Herman. So, Miguel looks in the front closet and immediately pulls out a baseball bat. He notes that it looks like it has been knocked around. Dexter has some handy-dandy chemical strips, which he brushes across the bat. The strip turns purple, which tells them that blood is present on the bat. He could have saved some child from an attacking dog, but we're just going to assume that he killed people. Miguel remarks that this sort of investigation is much more efficient than the bureaucracy he faces at work. Really though, it was in his front closet. The cops couldn't find it? Dexter says that they also need to find proof that he will kill again, because that's part of the Code. Miguel asks that Dexter write down this code for him (DON'T do that, Dex), but then he says that Billy kills when he needs to pay off debts. So, they should look for a ledger, because all of the gamblers that he tried kept really extensive records. There's a Confederate flag on his wall, which I guess is supposed to make us feel that he really should die.
