S09E10 finale
All bad things must come to an end.
Bored and unhappy as the Lord of Hell, Lucifer Morningstar abandoned his throne and retired to Los Angeles, where he has teamed up with LAPD detective Chloe Decker to take down criminals. But the longer he's away from the underworld, the greater the threat that the worst of humanity could escape.
Chloe returns from Europe after processing Lucifer's devil face, and Lucifer is shocked by her reaction. Maze processes what happened between her and Trixie, Amenadiel processes his visit to the Silver City, and Dan processes what happened to Charlotte.
