In 2011, Lucifer leaves Hell for Los Angeles. His brother Amenadiel demands that he return to Hell, but Lucifer talks him into delaying their departure. Amenadiel is shot and his necklace is stolen. Knowing the danger of exposing humans to divinity, he persuades Lucifer to help him find it in return for a favor. Meanwhile, beat cop Chloe Decker and her husband, Det. Dan Espinoza, investigate the murder of MMA fighter Aiden Scott. Lucifer abducts the promoter who tried to fix Aiden's last fight, summoning his demon torturer Mazikeen to interrogate him. Chloe visits the promoter's lawyer, Charlotte Richards, and pressures her into setting up a sting operation with her client. Lucifer sets up a fight with Amenadiel to show that they are the same. Amenadiel dominates the fight, but allows Lucifer to win by submission to prove that, unlike Lucifer, he can control his pride. The sting nets Aiden's mentor Gil, but Lucifer and Amenadiel snatch him up and force him to confess to murder and theft before leaving him to be arrested. Lucifer uses his favor to get Amenadiel to leave him on Earth. He also has Maze cut off his wings.
