In this episode Lucifer says he detests cats. In real life, Tom Ellis is a cat lover and has two cats named Cain and Abel.
While adding a bit of liquid nitrogen to a drink gives a nice foggy visual, it is absurdly dangerous. Liquid nitrogen dance's around on top of the drink, making it very easy to accidentally swallow. At -320°F, that is bad. In this episode the blue foggy drinks have bubbles rising from the bottom of the glasses because they contain pieces of dry ice, which always sinks.
Further connections to Greek mythology and to Neil Gaiman's work. Charlotte wears an apron and matching oven gloves decorated with poppies. In Greek myth, poppies have symbolic connections to death and to Morpheus, the god of sleep. Morpheus is one of the names of Dream/Sandman in Gaiman's Sandman comics, from which the Lucifer comics are a spin-off.
