Deb shows up at Christine's apartment, looking somewhat reticent. I like how Deb isn't entirely sure how to act around Christine. She's torn between the savvy cop she's become and the reactionary victim she's trying to keep under wraps. Christine looks like hell as they both sit down. "That motherfucker," she leads off. Deb thinks she's talking about Quinn, but it's her dad. Deb shocks Christine by saying they know who he is, but when Deb says "Stan Beaudry," Christine lets out a rueful giggle and just says, "wow." Yeah, at least Dexter won't be getting sandbagged by Crazy right here. Christine then returns to the subject of fathers and daughters. She only wanted to make her dad love her. But he hates her. Deb says he's a killer, she doesn't need his love. Christine then says she's a killer like her dad. "I shot you," she says, as Deb swallows hard. "And I killed Lundy." Deb holds it together as Christine says she is sorry, but not so much when Christine asks (perfectly sincerely but still) if Deb can forgive her. "Are you kidding me?" Deb says, breaking down. "I came here to do a job, and to take you in, and get justice for Lundy. But forgive you? Fuck you." She's hyperventilating now. I love Jennifer Carpenter something serious. Christine just closes her eyes. Deb says they should just get to the station, but Christine won't be doing that. She pulls a gun from beneath a pillow, and before Deb can make a move, Christine puts the muzzle up under her own chin and pulls the trigger. Quinn hears the shot from street level and comes running. By the time he gets up there, Deb's already in the hallway. She blocks him, but he looks in and sees the blood, the gun, and Christine's dead body. Think he'll ultimately find a way to blame this one on Dexter? Me too.
At the carnival, Dexter searches in vain for Arthur. He gets a call from Deb, who tells him about Christine. She needs her brother right about now. DVO dithers about multiple Dexter identities (the serial killer v. the brother, blah blah), but Dex makes a quick call: "I'm on my way." As he heads for the car, Arthur is watching him from the upper level. And in a mirror image of earlier episodes, it's Arthur who now follows Dexter through the streets of Miami.
