"It's good to be bad."
Lucifer - Easter Eggs & Hidden Details
Easter Eggs
In Season 3, when confronting Marcus Pierce/Cain (played by Tom Welling), Lucifer refers to Cain's invulnerability as his "kryptonite."
This is a direct, tongue-in-cheek reference to actor Tom Welling's most famous role as Clark Kent/Superman in the TV series "Smallville."
The title of Season 4, Episode 9 is "Save Lucifer."
This is a direct homage to the fan campaign and the #SaveLucifer hashtag that was instrumental in getting Netflix to revive the show after its cancellation by Fox.
In many scenes featuring the character Eve, there is an apple or apple imagery present, and her signature drink is an Appletini.
This is a recurring visual nod to her biblical origin story and the forbidden fruit from the Garden of Eden.
In the pilot episode, Lucifer tells Amenadiel, "I look forward to eating your heart one day."
This is a direct reference to the original DC/Vertigo comics, where the conflict between Lucifer and Amenadiel ends in a death match in Hell, with the victor being required to eat his opponent's heart.
In Heaven, the character Mr. Said Out Bitch says, "I don't know what the fork any of that means."
This is a clear reference to the NBC sitcom "The Good Place," where swearing is impossible in the afterlife and curse words are automatically replaced with similar-sounding, harmless words like "fork."
