September 19, 2016
As Lucifer helps Chloe with a murder case involving a stand-in for a popular teen show actress (Jessica Sula), 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 (Tricia Helfer) shows up at his door, seeking help.

She explains her story to Lucifer and they return to the hotel room that Mum last remembers being in, finding two murdered bodies.

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 Mum was not the murderer. With the crime solved, Lucifer chastises Mum for abandoning him when he was banished to Hell.

Lucifer seems to accept the explanation and walks away, after which Charlotte looks to the sky with a sly grin.

Chloe and Maze pose as a married couple and attend a party in honor of the deceased, where the real murderer, a teacher whose affair was discovered by the victim, is caught and subdued by Maze. Linda suggests to Lucifer that his inability to use the blade may be because he suppresses all of the pain and heartbreak in his life, and by channeling pain instead of anger, he is able to briefly ignite the Sword. It is revealed then that Charlotte is desperate to return to Heaven because her human form is weakening.

The real killer, one of the nurses, abducts them. Lucifer and God make peace with one another while there. After escaping the asylum, Lucifer discovers that Earl's belt buckle is part of Azrael's dagger, and that God possessed Earl while he was wearing the belt in order to talk to Lucifer.

Maze forces the chairman of the ethics board to restore Linda's license, while Charlotte accidentally kills Chet by exposing him to her true form after he stabs her.

#18 "The Good, the Bad, and the Crispy"
May 29, 2017
Charlotte calls in a favor to dispose of Chet's body, while Amenadiel insists that he be given some time to find himself before reassembling the Blade. Linda uses duct tape to hide Charlotte's wound, but when Lucifer arrives, he recognizes that his mother does not have much time before her human body "bursts". He assigns Maze to find Amenadiel while he works to cover up the murder. Unfortunately, Ella finds the cleaning company Charlotte hired, and Chloe confronts Lucifer about letting his personal problems interfere with work. Amenadiel refuses to reassemble the Blade, citing renewed loyalty to his Father. Charlotte escapes, apparently kills one of the cleaners, and forces Linda to reveal Lucifer's plan. She then threatens to kill Chloe unless the last piece of the Blade is delivered to her, which turns out to be in Dan's possession. Amenadiel uses his renewed angelic power to stop time, allowing Linda to be hospitalized. At the same time, the cleaner's real killer (Chet's brother) attempts to shoot Lucifer and Charlotte. With time stopped, Lucifer ignites the Blade and opens a dimensional rift to a pocket universe where his mother can create her own world free from God's influence. Later, the old Charlotte is revived, having no memory of the time her body was inhabited. A visit to Linda at the hospital encourages Lucifer to reveal his true nature to Chloe. Before he can, however, he is knocked out cold and wakes up to find himself in the desert with his wings restored.
