As Lucifer helps Chloe with a murder case involving a stand-in for a popular teen show actress, he becomes convinced that his mother's soul is occupying the body of the murderer to torment him. Lucifer tells Dr. Martin the story of how the union of his father and mother created the universe, but his mother was ultimately banished to Hell forever. Chloe tells Lucifer that she has some of his blood from the shooting and plans to test it to either prove or disprove his claims of being the devil. When Amenadiel finds out about this, he makes up a story for Chloe that portrays Lucifer as delusional, but human. Like Lucifer, Amenadiel starts to show signs of losing his angelic powers on Earth. Dan is reinstated to the police force, but gets demoted. Maze also returns from her absence, saying that she went to see a friend and wants to figure out how she fits into this world. At the end of the episode, Lucifer's mother shows up at his door, seeking help. Lucifer's mother is shown awakening in her new body in pain, finding a screwdriver lodged in her neck. She explains her story to Lucifer and they return to the hotel room that she last remembers being in, finding two murdered bodies. Lucifer is convinced his mother committed the crimes and gets Chloe and Dan to investigate. Lucifer later learns that the body his mother occupies is that of Charlotte Richards, a law firm's managing partner who had been having an affair with the man she recently promoted to senior partner. Cocaine is also found hidden in Charlotte's home, giving the team more suspects. The investigation ultimately shows that Charlotte was a victim and Charlotte was not the murderer. With the crime solved, Lucifer chastises Charlotte for abandoning him when he was banished to Hell. She replies that God initially wanted to end Lucifer's existence, but she convinced God to send him to Hell instead. Lucifer seems to accept the explanation and walks away, after which Charlotte looks to the sky with a sly grin.
