Now at BloodLab 2021, the VOing goes on: "If my back wasn't against the wall I'd almost feel guilty for hacking into Masuka's email. Once I got past all the porn, it was pretty easy." Dexter opens the list of all the people with access to M99 and erases his moniker, Dr. Patrick Bateman. Nice nod to all the American Psycho fans out there. "Harry would frown upon me destroying evidence, but he didn't want me to get caught, either." "What are you doing in here," asks Deb. Dex wheels around, looking guilty for a second, and comes up with an excuse about how his computer crashed. Deb wants Dexter to take a look at her copycat killer profile, which he looks at skeptically. She mentions that she worked all night on it. "I want to give it to LaGuerta but I want to make sure it's good enough." "I'm honored," says Dexter. He reads some of it aloud, and it's pretty right on the money, talking about how the killer feels a connection to the ITK and how the cut on the cheek, "while not fatal, appears to be a signature of sorts. Because of the lack of evidence found at the crime scene, the suspect may be familiar with law enforcement or forensics procedure." Damn, Dex. Sounds like Deb's got your number, son! In order to throw her off his scent, Dexter plays on Deb's insecurities to get her to drop it. "Let me guess: Single white male, mid-30s, lives alone, disconnected from his emotions? It's a little textbook, don't you think?" "But it totally fits this case." "Or, you're trying to make it fit." Deb's face collapses a little bit. "My advice," Dexter continues, "is keep this to yourself. You're new to homicide. This blows up in your face, it gives LaGuerta the excuse she's been looking for to send you back to vice." Well played, Dexter. Or was it? Deb stands up, and says, "No. I'm on to something here, I can feel it. Like one of your hunches." Then, choking back tears: "Way to have my back." Ew, dude. Okay, granted, Dexter was trying to get her to drop it because, obviously, he killed Valeria Castillo. But why, when Dexter has been the source of all of her leads up to now, would she turn around and give him shit? Mmm, mmm, mmm, what a little asshole.

Flashback. "Where's your sister?" Harry asks Teen Dex. Turns out she's outside shooting cans with one of Harry's handguns. "Debra! What the hell do you think you're doing?" He asks her. As he unloads the gun after snatching it from her, he asks, "How did you get into my cabinet?" "You had the key in the pantry." Harry gives her shit, and she retorts, "I was being really careful. I was only shooting at bottles and cans [just clap your hands], and I'm really good like Dexter. Now we can all go hunting together!" Harry isn't having any of that shit, and tells her how disappointed he is in her. "Grab your things," he says and leads her back home. "Thanks a lot," she says to Dex as she passes him. Sound familiar, dude? Yeah, she can be such a baby sometimes.
