The tension in Dexter's life is becoming palpable, as the BHB investigation starts getting ever closer to revealing that he's the real killer. Compounding Dexter's awareness of this is his realization of his mother's affair with Harry, as well as Special Agent Lundy taking a special interest in him, which Dexter misconstrues as suspicion (actually, Lundy's just sick of Masuka's "titty jokes").
Doakes brings up Dexter's involvement in NA with Deb, who says she has no clue what he's talking about. Naturally, Doakes gets suspicious of this, and gets back on Dex's ass, and his snooping leads him to the audio tape of Harry and Laura Moser. Dexter discovers him sticking his beak in, and tells him to "back the fuck off," and Doakes threatens him. Dexter wants to file an official complaint against him to LaGuerta, who wants to talk to Doakes first. She tells Dex to take the rest of the day off.
On the BHB case front, the surveillance footage from the Corral Cove Marina hasn't been reviewed yet, so Dexter has a small window in which he can get in and erase the files, which he's eventually able to do, but only because he pulls the fire alarm like a middle-school troublemaker. Also, it seems that the good folks of Miami are getting a little bit of "BHB fever," and there are some copycat killers popping up. One the main suspects piques Dexter's interest, and Dexter goes to his house to confirm that he really is just a copycat. When he discovers the guy actually is a killer, and not just a copycat, he kills the guy and leaves the bags for the cops to discover. Boy, he's losing it.
On the personal front, Rita's mom convinces everyone that Lila should come and have dinner. She puts on a good front, but almost lets slip her knowledge of how Dexter's mom died. Later, as Dex and Rita are making out at his house, Lila leaves a loud, overly- and unrealistically-detailed message about how she almost let slip about Laura Moser's murder and their road trip from last week. Rita gets upset, assuming Dexter boned her, and tells him "it's over." Of course, it's not really, but when Dexter's "on break" at LaGuerta's request, he goes to Lila to vent, and ends up porking her...while kind of choking her. It's…pretty hot. Anyway, when Rita finally gives Dex a chance to explain everything, he tells her about his mother and how she died, and then lies that he and Lila had separate rooms and that she was just there for "emotional support, as my sponsor." "So, you didn't have sex with her?" "No. Not that night." Yeah, so...see ya, Rita. Yikes.
Previously: Dexter discovered that Harry and Laura Moser knew each other before she got hacked to bits. Mama got Dexter to admit he was in NA. Doakes told LaGuerta that he was "fine" after shooting two guys in six months. Deb wanted to know if Lundy was trying to play dad. Dexter took a road trip with Lila, and decided to not tell Rita. Dexter's marina was put under surveillance because the algae led the cops there. Deb told Dex to consider moving his boat. Dex got to his boat to eliminate any blood trace, but there was a camera already in place.
"There's another shipment coming in tomorrow. Cocaine," says Laura Moser, the camera practically slapping her in the face. Seriously, you can see every downy hair on her upper lip. Harry wants to know how much, and she tells him it'll be around "three-hundred bricks, give or take." "Can you get your hands on some?" "No, Harry, that wasn't part of our agreement." Harry tells her he needs hard evidence, "otherwise, it's just your word against Estrada's." She looks worried, but Harry assures her that he'll protect her, which we all know he totally didn't. "You better," she says, and then, grabbing his hand, wonders if Harry wants to meet her later, presumably for boning. "Laura, the tape's still rolling." Not wanting to get caught, she leans in and whispers something unintelligible into Harry's ear, as we come out of Dexter's mind into his lab, where he's listening to the thirty-year-old tape. "What was that?" Dexter whispers as he rewinds the tape. "My mother, confidential informant. And mumbler. Whatever sweet nothings she had to whisper I probably don't want to hear. It seems my foster father and my biological mother were having an affair. It's bad enough I can't shake the visual, but the questions -- Did he blame himself for her death? Is that why he took me in? Did he love her? Or was he just using her? Was he using me? I always thought Harry's code was on-the-spot creative problem-solving, but maybe he planned for me to settle the score all along. It's times like this I wish I really were a drug-addict." Damn, dude. That's some pretty heavy ish, bro. Huh? What did I just say? No, that was you.
At Lila's house, Dexter is going off, spouting a thousand words a minute about his insecurities and Harry's rules. "I spent so much time trying to live up to his expectations because I thought he had my best interests in mind, but now --" "If you're gonna come over this late, the least you could do is bring me a coffee," says Lila, obviously disinterested in Dexter's tale of woe. Dex apologizes, and Lila heads over to the kitchen to fix herself some. "Truth is, Dex, is doesn't really matter why Harry did what he did. The result's the same. You have an addiction." "Do you think Harry made me what I am?" Lila explains that plenty of people go through shit in their lives that don't make them addicts. "Whatever Harry taught you led you down the wrong path." Dexter explains that he built everything in his life on what Harry told him: "My job, my girlfriend. It's all what Harry told me I needed." Lila asks Dexter what he thinks he needs. "I have no idea," he responds honestly. "Whatever's inside you is spattered all over that paper I took from your lab," she says, motioning to the now-framed blood spatter test paper. I totally want one of those. "Looks messy," says Dex. "Probably is. Look, Dexter. Everyone has a moment when they realize their value system is different from their parents'. Mine was in college, but maybe you're a late bloomer." "Lucky me," says Dex sarcastically, but Lila tells him that he is lucky, because now he can make some of his own decisions, and figure out exactly who he is for himself. He looks frightened and vulnerable, and the way he's lit makes him look like a little boy.
