Somebody's Been Reading Dante's Inferno - S4-E2
Stupidity: Chloe finds a new suspect, the cameraman. She goes into his shed and starts talking to him with her back turned towards him as she's looking for the murder weapon; knowing he very well committed the murder. She turns to draw her gun and the cameraman is standing a good 10-12 feet away with an axe, and he says "I wouldn't do that if I were you." A gun vs an axe, the gun will win, she had every ability to shoot him, and secondly going at a murder suspect with no backup is just another stupid move. (00:40:40 - 00:43:10)
Answer: As Cain theorises in a later episode, it's Chloe's love, not presence. This early on, Chloe had no strong feelings for Lucifer, so had no effect on his immortality. In fact even more recently he's back to being invulnerable around her after speculation that he chose to let himself be vulnerable. So while there's a degree of flexibility / retconning going on, it's all explained in-show.
