Lucifer retrieves Azrael's blade, which turns out to be the Flaming Sword that once guarded Eden and can cut through the Gates of Heaven, allowing Charlotte to return home. As the Lightbringer, Lucifer is the only one who can reignite the blade, but fails to do so as it can only be triggered by extreme emotion. Chloe and Dan investigate the murder of an admissions officer at a prestigious elementary school; despite uncovering embezzlement by the assistant dean, they are unable to find any leads. 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.
