Why? Because it fully explores the trauma and doubt both Chloe and Lucifer are dealing with. Who can blame Chloe for trusting the Vatican on matters of the devil? And yet, who can blame Lucifer for feeling the deepest betrayal, especially after his deep issues with being thought of as the ultimate embodiement of evil by well, everyone (even his own brother thought that in the episode where they show Lucifer's first day on Earth on his latest trip, five years prior to the start of the series).
The best part is that while Chloe pretends everything is fine in episode one, it took three for her to fully come to grips with 3.24's reveal, and her answer to why she would do what she did, and her delivery, are simple but perfect: "Because I'm terrified!" And then her obvious fear and revulsion as he reveals his true nature to her again, contrasted with her internally conflicted emotions about her loyalty to Lucifer (which of course was severely tested), is not only a great piece of writing, but a great piece of acting. As is Lucifer's obvious hurt.
It's a great episode because it really drives the characters.
