In the eighth episode of Season 5, Ella (Aimee Garcia) is dating Pete (Alexander Koch), and he's just given her a key to his place. Things are going awfully fast for Ella, but Chloe tells her to take it in stride. Meanwhile, Chloe, who's looking for a serial killer, has gone missing in the middle of an investigation.
As Lucifer tracks down a lead, Ella goes to Pete's house to find his research on the killer from his job as a newspaper reporter. But she finds something else. Behind a wall is all the paraphernalia of the serial killer. Pete is the culprit, and Ella's found him. The trouble is Chloe is still nowhere to be found.
It turns out that Lucifer's twin brother, Michael, has stashed her in a cave. Lucifer, Dan, and Maze rescue her, and Maze stays behind to confront Michael, but Michael tells her that he can get her what she wants. So when time stops at the end of the episode and everyone else freezes, Lucifer and Amenadiel take on Michael and Maze in a thrilling fight. That is until Lucifer's father interrupts — yup, God — and tells them to stop fighting.
