Wicked City

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.

Jack focuses on a woman from the past who may have been the catalyst for the murderer’s current killing spree; Betty decides to go all-in as Kent’s partner, and together they troll a club in search of a victim; Karen is offered a job with Rolling Stone, which does not please Diver; a menacing old flame of Betty’s reemerges and sets his sights on trying to reignite their troubled past; and Dianne finds herself in dire straits when her allegiances are questioned by a powerful drug lord.

Jack and Paco question Kents co-workers and find out his "real" name, Kent Grainger, but no records are found about him. When going through files from the auto shop, Paco discovers a Xerox of Kents I.D. Kent visits Betty at the hospital; she takes him to the morgue so they wont be seen, where he proceeds to break up with her, fearing that the police will catch them both if they dont part ways. Kent dyes his hair in an attempt to conceal his identity. His acquaintance, Bobby, creates new I.D.s for him; he then ties her up and locks her in a closet. Meanwhile, Betty disguises herself as a makeup lady and visits Jacks wife, Allison, at their home. When leaving, she takes a photo of the family and a set of keys to the house. Mary calls the polices hotline to give Kents address, but her dyslexia mixes up the house number. Elsewhere, during a live interview on Eyewitness News, Karen gets a call from Kent, who says that the story hasnt yet had its climactic ending. Diver identifies a song playing in the background of the call as "Suicide Solution" by Ozzy Osbourne, and suggests Kent might kill himself. When the police realize Marys mistake, they arrive at her house just as Kent causes an explosion in his home across the street. Betty arrives home, thinking Kent is dead, but he surprises her with the fact that the burned corpse belongs to Jimmy. As the two kiss, the residents of Los Angeles think the Hollywood Slayers reign of terror has ended.

Kent approaches Jack, saying he is not the killer. As a concert begins, Kent runs off, with Jack chasing after him. Jack catches him and takes him into custody. Karen tells Diver that Kent called her again, and his request for her to write a piece on Jack and Diannes affair convinced her to do the opposite. Allison finds out that Vicki lost her virginity, as well as that Vicki knew about her fathers affair. Kent is granted a phone call; he calls Betty, setting their plan of getting him free. During the interrogation, Jack makes Kent look at all the compiled evidence. Kent continues to claim that he is being framed. He says that his grandfather is the killer, but Jack isnt convinced. Kent then claims that it was Dave Keller, his co-worker, but no evidence can back the theory up. Karen does a TV segment warning the people of Los Angeles to stay safe. At the club, Dianne is told that Karen has been looking for her, as well as a "blonde chick" which later turns out to be Betty. Paco tells Jack that they found Fly Brand cocaine and a missing girls ring in Daves car; Jack says that Kent most likely planted them there. On TV, Karen tells the world that she is the voice of Kents victims. Betty kills another girl and drops the body at the Santa Monica Pier, prompting Jack to realize that Kent has a partner. His captain gives him an hour to find Karen, in order to identify the Hollywood Slayer, or Kent goes free. The body at the pier ends up being Karens. Back at the precinct, Jack angrily lashes out at Kent as he leaves custody. Six months later, Dianne returns to work at the police station. Paco and Jack vow that the next time Kent and Betty make a kill, they will catch them. Kent and a visibly pregnant Betty are shown living in Chicago. The series ends with Kent dedicating Foreigners "Feels Like the First Time" to a new victim.
