Deb and Quinn question Jordan about his connection with the missing Cole, Boyd and now Alex Tilden. Meanwhile, Lumen and Dexter plot to get Jordan, and it's all very lovey-dovey. Lumen asks Dexter if Deb has ever suspected anything about him. He says she has a blind spot when it comes to him. Then, his baby monitor picks up the signal of the camera that Liddy has planted in the apartment. Liddy tells Quinn that he wants help getting his job back. Quinn refuses.

Dexter finds the camera, which has a "property of the police" sticker on it. He tells Lumen that they have to lie low, but she is anxious to continue their vigilante crusade. Masuka finds evidence that Cole was killed in his home, which gives further weight to Deb's vigilante theory. LaGuerta points out that a woman would have a hard time overpowering these big guys and Deb says she may have help, from a man. Dexter is there for this talk and looks to be shitting himself. Dex finds out that Quinn checked out the surveillance equipment in his apartment. He also finds out that it's not police business, that Quinn is doing this on his own. Lumen and Dexter search Quinn's apartment and find that he's a fan of cute cat YouTubes. They also find Liddy's photos of them dumping Cole's body into the marina.

HOLY SHIT, Mary Cherry is Dan the Dentist's wife. Deb talks to her and finds out that he would leave for trips with "the guys." The only name she recognizes amongst the teen friend killers is Jordan's. She knows that his real name is Eugene Greer and tells Deb and Quinn. So, they know Jordan was lying about knowing them. Deb tells Dexter that Quinn thought he had something to do with Rita's death.

Dexter tries to get Lumen to leave, but she refuses. Liddy totally tazes Dexter and kidnaps him. Meanwhile, Lumen gets a call from Emily Birch. She says that she was called by Jordan Chase. She wants to go to the police, but Lumen convinces her to wait for her and Dexter. Since she can't get ahold of the kidnapped Dex, she goes by herself. Emily, of course, is calling at Jordan's behest. Liddy tells Quinn to meet him. Lumen gets to Emily's place and Jordan's there. Scary. Liddy tries to force a confession out of Dex, but there's a struggle and Dex kills him, JUST as Quinn is walking to the van. Quinn doesn't uncover the scene, but Liddy's blood drips out of the van onto Quinn's boot.

Then, Dex gets Lumen's message that she's going to Emily's. He tosses Liddy's computer into the water then books it. I can't see why Lumen doesn't just take out Jordan by herself. I feel like she could. Then, she tries to escape and he throws her to the ground. Emily gets upset, so he kills her. Dexter arrives to find blood everywhere. But, it's just Emily's. Lumen and Jordan are nowhere to be found. Deb gets a court order to keep Jordan from leaving on his private jet, but Jordan doesn't show up at the airport. Dexter follows a trail outside of the house. He also finds Lumen's knife. Without saying much, even in VO, you can tell that Dexter is getting pissed. Somebody's getting cut.
