Deb and Batista prep Yasmin, the hoochie witness. She's nervous. Manzon and Quinn are already in the club, as is LaGuerta. Yasmin says that the Fuentes brothers are already inside. LaGuerta already fucked this up. She says that it's a change of plans and tells Yasmin to go sit with the brothers. Not good.
Dex and Lumen are waiting outside of Cole's house. When the neighbor goes to sleep, Dex goes in and makes Lumen stay outside. Back at the club, one of the brothers calls Manzon over. Deb says that she shouldn't, but LaGuerta tells her to talk to them. Deb is freaked because of the danger involved. The dude immediately starts groping Manzon and sees that a of all, she's maybe wearing spanks, or b of all, some sort of police stakeout equipment is stationed on her upper thigh. Either way, he's furious. He jumps up, as does his brother, who pulls out a gun and shoots...into poor Yasmin. The other brother decks Manzon. Shooting everywhere. Deb runs in and corners one of the brothers who grabs a woman and holds a gun on her. Deb tells him to drop the gun, he doesn't, so she shoots him square between the eyes. She's stunned but cool when Quinn checks on her.
Dexter is looking around Cole's place. He sees a pic of Cole as a teenager with a bunch of other dudes. Suddenly, Dexter is grabbed from behind. His knife is on the bookcase and he can't reach it. Then, Lumen is there and beating the living shit out of Cole with her new flashlight. As Cole groans on the ground, Dex grabs her and says they have to get out of there before he sees their faces. In the car, Lumen seems exhilarated. She says thought she saw a shadow and Dex is surprised that feeling made her crash through a window. She says it must be some lizard brain thing and Dex VO's that she's beginning to sound like him. He shows her the picture of Cole as a teen. Boyd and Dan the dentist are in it as well. Dexter doesn't know what this means, but Lumen is psyched. They just need to find out who the others are. She reaches over and hugs Dexter. He asks her what she should do next and she barely conceals a knowing smile. This scene is the best acting Julia Stiles has done on this show and her performance has been pretty high-quality throughout. Dexter asks her what she's smiling about and she points out that he said "we." He doesn't acknowledge it, but instead tells her to put on her seatbelt.
LaGuerta, with Batista by her side, tells the captain that Carlos Fuentes and Yasmin were shot and killed. Another innocent by-stander was shot and killed by a Fuentes and a few other people were hurt. The captain says this is a disaster and he wants a full report in the morning. After he's gone, Batista tells LaGuerta that they will get through this. In the heat of battle, all cops make mistakes. "Excuse me?" says LaGuerta. "If mistakes were made, they most certainly weren't mine." Then, she walks out as Batista has a look on his face like, "Am I here? Did that just happen? Did someone just flip the script?"
