Lucifer, Amenadiel, and Charlotte cut a deal with a smuggler for the last piece of the Blade. However, the smuggler is robbed and murdered before he can turn over the piece. Lucifer gets Chloe assigned to the case, who discovers that the killer is Chet Ruiz, one of Charlotte's clients and a powerful crime lord. Amenadiel and Dan bond over feeling unable to compete with Lucifer. Linda is stripped of her medical license for ethics violations and Lucifer unintentionally botches her appeal by revealing his sexual arrangement with her. Maze attacks Lucifer for manipulating her during their time on Earth. Charlotte is coerced into stealing Chet's phone from the police, but Chloe finds out. She also learns that Charlotte is the "ex-wife of Lucifer's dad" and gets her to take part in a sting operation. The piece turns out to be a rare tome that only Amenadiel can read. Maze forces the chairman of the ethics board to restore Linda's license and Charlotte accidentally kills Chet by exposing him to divine light after he stabs her. Lucifer and Amenadiel discover that the latter's necklace contains the third piece of the Blade and that Amenadiel is their Father's favorite son.
