Running with the Devil

Running with the Devil is the second episode of ABC's Wicked City.

Plot
Jack and Paco get a lead on the serial killer's next possible victim and race against the clock to try and track her down before the killer gets to her; Kent struggles over whether or not to invite Betty to take part in his murderous rampage when it becomes clear that she doesn't trust him and may leave him, and Jack and Paco continue to search for Karen, who has disappeared from the club.

Summary
Jack and Paco search for Karen, while Kent and Betty have a twisted threesome with Mallory. Karen and Diver go to LA Notorious, where Diver tells Karen to use her fight-or-flight response to write a story about the killer. The next morning, Mallory disappears, prompting Kent to disguise himself as a cop in order to find her. The two detectives locate Karen and get her to meet with a sketch artist; the resulting drawing is disseminated around town, including the hospital where Betty works. Betty confronts Kent about his obsession to find Mallory and shows him the sketch. Paco trades details about the case for information from Diver, who puts the cops in touch with Bucket, a Fly Brand cocaine dealer. The police get a lead when they tap a phone call Kent makes to Mallory's apartment. Karen prepares to leave Los Angeles because the killer knows too much about her, but Diver tries to make her stay. They then give in to their mutual attraction and sleep together. Afterward, Karen gets a note through the door from the Hollywood Slayer, asking if she "wants to play". Jack goes to an upholstery warehouse and finds a corpse holding a note, informing him that his lead was a set up. Kent takes Betty to the spot where he murders his victims and stabs Mallory to death as Betty watches.
