Before Chloe was born, God sent Amenadiel to earth to bless a couple who were having difficulty conceiving a child. Amenadiel later realized that the couple he had blessed were John Decker and that Chloe had been the result of that. Chloe was born later in 1981.
Chloe’s father was an officer with Dan Espinoza, who was also an officer with the LAPD. They later married and had a daughter named Beatrice (nicknamed "Trixie"). Eventually Chloe and Dan split up, as she believes he always puts work before his family and never has time for her.
In the series [ ]
At the beginning of the episode "The Devil’s Time Out" Chloe first meets Lucifer Morningstar after aspiring musician Delilah is killed in a drive-by shooting outside Lucifer’s club Lux. Lucifer had used his influence to lure her into the spotlight, and although he treats most of humanity with bemused indifference, he takes an interest in finding Delilah’s killer and becomes Chloe’s unwanted partner. Thanks to Lucifer’s powers of persuasion, he is able to get enough information about the killer from psychiatrist Linda and track him down. The perpetrator, Delilah’s manager Jimmy, wanted the singer’s untimely demise to increase music sales. In a fit of rage, Jimmy shoots both Chloe and Lucifer – the bullets have no effect on the latter, and Lucifer makes sure Jimmy gets his punishment before rushing Chloe to the hospital. While Chloe is recovering (and trying to figure out who this guy really is), Lucifer decides that it would be fun to see criminals in L.A. to punish.
In "The Devil in Therapy" Chloe is released from the hospital, but is on sick leave. She uses the time to snoop around Lucifer’s past and finds out that the person is "Lucifer Morningstar" which did not exist until five years ago. She also tries to find out why the bullets could not harm Lucifer. A new case, however, turns Chloe’s attention in a different direction, as the son of a movie star was killed in a car accident. Paparazzo Nick, who stalked Chloe at her father’s funeral, confesses to the murder, but Chloe doubts it. Lucifer uses his powers and gets the truth out of Nick.
In "Sin Eater Dan and Chloe get divorced for good.
In "Girls’ Night Out Chloe searches for a new home. After a few glasses of alcohol, she agrees to share an apartment with Maze. At the end of the episode, Chloe is hit by a car after finishing a conversation on the phone regarding her new apartment.
At the end of "Monster", when Chloe overpowers the killer, Chloe shows genuine concern for Lucifer, telling him he was stupid and reckless, but he saved a woman’s life. However, Lucifer tells her that he didn’t take care of the woman, and Chloe asks him if he tried to kill himself. When she realizes that this was exactly what he had in mind, she tells him that he is not so. Lucifer tells her she doesn’t know who he is or what he did. Chloe finds out that he wants to be punished for something, and that is the reason why he acted the way he did. She asks him to talk to her, but Lucifer tells her she can’t understand and never will. Chloe is hurt by this, but she tells Lucifer to talk to his therapist "talk to her before it eats you alive".
At the beginning of the episode "Stewardess Interruptus" Chloe and Lucifer eat fries and hamburgers together for dinner. Both feel a special moment and lean forward to kiss. Lucifer interrupts, however, and says that he ordered fries, but not ketchup. Chloe then says that she hates ketchup. The elevator opens and Janna, the stewardess – one of Lucifer’s former lovers – interrupts them and calls out Lucifer’s name. Chloe and Lucifer look at Janna in surprise and Chloe, annoyed by Lucifer, gets up and wants to leave. Lucifer stops her, however, and tells her that he didn’t know Janna was coming, and she replies that she’ll give them ketchup. This statement stops Lucifer from telling her that they had a moment and he doesn’t want her to be angry. Chloe claims that she is not angry, but glad that Janna showed up. Lucifer wonders about this statement and asks her why she is happy about it. She responded by saying that Janna had stopped her from making a mistake. Lucifer tries to shout something at her, but the elevator is already closing.
Towards the end of "Stewardess Interruptus" Chloe tracks down Lucifer via his smartphone. She finds him standing on the beach with his jacket thrown over his shoulder. She jokes that she still has paperwork to do, which Lucifer pulls into a "moment" transformed. To her surprise, Lucifer tells her that he’s going to stop trying to create "moments" like this to have with her and she deserves someone better than him because he thinks Chloe is special. Chloe says, "You’re probably right.", before she leans over to kiss him.
In" Once upon a time …", set in an alternate universe created by God, Chloe’s life is shown as it would have been if her father John Decker had never been murdered. In this universe, Chloe remained an actress because her father did everything he could to keep her from being interested in becoming a police officer like him, which led to her becoming famous as a car thief, as the car thief became police officer Bonnie Gennaro in the Weaponizer movie franchise. This led to her never meeting Dan and never having Trixie, which means she has no child in this reality. She also never met Lucifer, Maze, Amenadiel and Charlotte, although she knows Linda because she was one of her patients at one point. This led Chloe to help Linda start a reality show called Doctor Linda, in which she appears as a therapist to celebrities. When a friend of hers is murdered, she goes against her father’s wishes and poses as a police officer to get information, which led her to meet with Lucifer, who is also investigating the murder since it took place at the Lux. The two worked together to find the killer, and after her father said he was proud of her, the two humorously discuss the possibility of Chloe becoming a real cop while Lucifer works with her, suggesting that the two will end up doing the same thing in this universe as they did in the original one.
