|“|| Chloe: I can let my guard down with you. I don't do that with anyone else. You make me vulnerable. And... maybe that's okay.
Lucifer: Detective... if it's any consolation to your pride... it appears you make me vulnerable, too.
| — Chloe & Lucifer|
in "St. Lucifer"
Lucifer and Chloe first began working together, trying to learn who was responsible for the death of a young famous pop star, Delilah. Since then, Lucifer and Chloe begin to work together on several cases. While Lucifer enjoys working with Chloe, she often finds him irritating and unbelievable due to his odd behavior and refuses to acknowledge their growing partnership. However, Chloe also tries to learn more about Lucifer as she witnessed unexplainable events regarding him.
Eventually, Chloe admits that she does enjoy working together with Lucifer despite how he may act and when Lucifer officially becomes a civilian consultant for the LAPD, they officially become partners. Lucifer is known to be openly honest with Chloe and constantly assures her of his true identity as the Devil. While Chloe still denies that Lucifer is the devil, Lucifer has discovered that her presence weakens him for a mysterious and unknown reason. Lucifer and Chloe are known to clash on occasion as Chloe becomes annoyed by Lucifer's behavior and Lucifer becomes irritated as Chloe wants to follow an investigation by the book. However, despite their differences, Lucifer and Chloe have developed a close bond together as both friends and partners. Lucifer and Chloe come to rely on each other for both their help and personal issues.
Lucifer is also shown to be openly attracted to Chloe, who constantly rejects his advances, confusing Lucifer since all other women easily fall for his charms, he is unable to understand her refusal. However, unknown to either of them, Lucifer and Chloe both begin to develop genuine romantic feelings for each other. While everyone, including Amenadiel, Linda, Maze, Trixie, and Dan have come to realize their feelings for each other, Lucifer and Chloe are oblivious and deny this claim. However, Lucifer and Chloe have recently come to realize their growing romantic feelings. Chloe finally becomes aware of her true feelings for Lucifer as she became jealous seeing him work together with Ella Lopez and Lucifer finally acknowledges that he truly has real feelings for Chloe as Linda helped him realize during a therapy session.
"Once Upon a Time" shows an alternate universe where Chloe and Lucifer never met due to John Decker not being murdered and Chloe remaining an actress, becoming famous because of it. This postponed their original meeting by approximately two years. In the alternate universe, they meet while both were investigating the death of Chloe's friend, who was killed in Lux which caused some problems for Lucifer when trying to expand the business. Lucifer instantly recognizes her from her films, and after some antagonistic interactions, the two agree to work together. This allows them to find the killer. Later, privately celebrating their victory, Chloe reveals she has an interest to be a police officer in real life as opposed to playing one in films, and Lucifer suggests he could tag along with her. This shows that regardless of what is changed, the two would inevitably end up working together to solve crimes.
