Lucifer - 5.02 - "Lucifer! Lucifer! Lucifer!"**The following is a detailed recap of the episode, which means it's full of spoilers. Please don’t read any further until you’ve watched it. You can also check out my spoiler-free review for the season if you prefer**
An astronaut (Ashlei Tave) opens a sealed room in what looks to be some kind of spaceship. She sneaks with a knife over to one of the sleeping passengers and uses it to break open their lockbox. She pulls an apple out and starts to eat it, when suddenly another astronaut comes from behind and stabs her.
Chloe (Lauren German) looks for Lucifer (Tom Ellis), letting a still annoyed Ella (Aimee Garcia) realize he’s back.
Meanwhile, the doppelgänger (Ellis) practices Lucifer’s accent and talking to Chloe while naked in front of his mirror.
Chloe and Ella investigate the murder of Judy Mason, a biochemist and commander of the Red 2 Mars project, a simulation engineered by Brody Aerospace, run by Anders Brody (Stephen Schneider), the tech billionaire, who Chloe says she talked to last year on a boat. Ella says that now he has a spaceship and was planning to take rich civilians to the red planet to be the first Mars colony. Judy, who was the only scientist, was stabbed in the neck. They find a hair in a bloody footprint, but the killer must have cleaned, because none of the suits had blood on them. Since no one is allowed in or out of the dome, they assume killer has to be one of the five crew. Most of the camera footage has been wiped.
