At Chloe's birthday celebration, Lucifer receives word that Candy, his ex/fake wife, has disappeared. Without telling Chloe, he and Ella travel to Las Vegas, where they find a woman dressed as Candy murdered in her apartment. Lucifer suspects that a loan shark who once tried to seize Candy's father's club was responsible, but he turns up dead as well. While investigating the loan shark's wife, a pit boss at a nearby casino, Ella is caught counting cards at blackjack and she and Lucifer are thrown out. Candy, who had been posing as a waitress while following the same lead, admits that the dead woman was a friend of hers. Lucifer and Ella set a trap at her father's old nightclub and discover that Jedd, the bartender, was the killer; Ella subdues him and they return home. Entering his penthouse, Lucifer discovers that Chloe, Dan, and Linda threw a party and attempted unsuccessfully to break into his safe. After admitting to Chloe that he was wrong not to tell her why he was leaving, he opens the safe and presents her with a gift---a necklace made from the bullet she shot him with when they first started working together.
