Dexter agrees to help Lumen kill more of the guys that tortured her. Someone has a car accident and spills the girls that Boyd had left in the barrels in that swamp. Dexter and the department are on the case. Dexter sets out to find the guy who was driving them, who got away. When he's investigating the scene, he sees Lumen looking on from the sidelines. Liddy tells Quinn that Dexter took down the "For Sale" sign at his house -- Lumen is living there now. Deb finds that Jordan Chase is the owner of the car that was driving the dead girls. Jonny Lee Miller!
Apparently, the Santa Muerte case is still open; Laguerta tells everyone that they are going to perform an intricate stakeout. The Chief gives her a lot of pressure about solving the case. Jordan Chase reports to the Homicide Department, where Masuka falls all over him. Good stuff. He makes a good show about needing all of this to stay quiet. Lumen recognizes Chase's head of security as a guy who attacked her. This episode makes Masuka seem like he's a bastard/torturer in the making. Dexter and Lumen break into Boyd's place. They scrub away any trace that Lumen was there. Dexter plants Boyd's wallet near the car wreck scene. They speak to Chase again and he says that he doesn't know anything about Boyd. I think we all know where this is going. Jordan congratulates his assistant for driving the investigation towards Boyd, but the hack tells him that he didn't do it. Dex tells the nanny that, though she wants to keep a saint doll with Harrison, he doesn't believe in any of it. She's clearly bothered.
Liddy starts pressing Quinn for more money to make things happen. RoboCop tells Quinn that his priorities are out of place, so he gives him more money. Quinn is planted in a club to find the Santa Muerte bitches. Laguerta is there, too, and sends their witness to hang out with them, even though she's very nervous. Because Laguerta was afraid of not making the chief happy, she pushed things hard and Manzon was put in danger and several people (including one of the Fuentes guys) were killed. Dex and Lumen broke into another guy (Cole's) house and killed(?) him. Dex feels like Lumen thinks like him. Something weird is happening with the nanny. She's nice and all, but she's too fine an actress to not be some sort of killer. Dex introduces Harrison to Lumen. He's found a partner, whether he wanted it or not.
Dexter asks her for details. I'm thinking that he wants to know about some sort of information that she has perhaps become privy to as she was taping things on this giant map, but instead it appears that she's giving him details about her torture. She says that, other than the of her tormentors that they have "taken care of," they still have to find "watch guy." She would be blindfolded in a room and unsure if there was even anyone else in it when she would suddenly hear a watch ticking next to her ear. Then, the guy would whisper to her, "Tick tick tick. That's the sound of your life running out." No sir, that's the sound of a watch. "Bla-bump, Bla-bummmp, Bla." That's really more like what I'd imagine it sounds like when someone's life runs out. Or, "I'm leaving you, gotta run." "Wait! You're my life!" That too, but that's a little esoteric. She says he would wear a suit and tie and would take off his jacket and fold it. He would also take off her blindfold, because he expected her to be dead soon. Dexter points out that he was wrong. So, Lumen knows what Suit Guy looks like.
It's nighttime at what appears to be the swamp where Dexter first saw Boyd dumping the body. And, look at that, there's a man getting out of a truck and he's wearing a suit. And, he folds the jacket. He's making this very easy for us. There are a bunch of dudes in the back of the truck. He holds a flashlight while the guys wade out into the water. They start retrieving the barrels with the girls in them. Meanwhile, Lumen is telling Dexter that she wants to be a part of the whole revenge thing with the killing of her tormentors and he tells her that he doesn't need a partner. She really wants to though. So, the guys get all of the barrels loaded onto the truck and leave.
