For fans of the DC Comics/Vertigo-based television series Lucifer, the big question they want answered going into Season 4 is how will Detective Chloe Decker (Lauren German) react to discovering that Lucifer (Tom Ellis) is actually the Devil himself. While this massive change in the duo's relationship will undoubtedly drive the bulk of Season 4 forward, we now have a bigger idea of the general story that will unfold when the series returns.

TV Insider has exclusively confirmed that Imposters actress Inbar Lavi has been cast in the biblical role of Eve, the first female human and, you guessed it, the first sinner of mankind. According to the official character breakdown, "After an eternity with Adam, she’s grown restless in her marriage and longs for a less predictable time when things were exciting. Naughty. Dangerous. She misses her hot and heavy first love...the charming rogue who tempted her so many years ago. That’s right, the devil himself…Lucifer."

As you may know, in the Bible, Eve was the first ever human to commit a sin, after being pushed into temptation by Lucifer himself. Thanks to him, Eve bit into the forbidden apple of the Garden of Eden, and plunged all of mankind into a cruel world of sin. It was previously reported that Season 4 of Lucifer would feature a new character from the title character's past that would change everything, and it now appears like we have our answer. With Lucifer and Chloe's relationship now reaching an incomparable turning point, Eve's arrival will surely offset everything about the duo's already-shaky relationship.

Both Season 2 and 3 of Lucifer featured the addition of a new recurring character in the form of the Goddess of All Creation (Tricia Helfer) and the Sinnerman (Tom Welling) respectively, each serving as the antagonist in their own seasons. If that is anything to go by, Eve will not only be a thorn in Lucifer's side, she will possibly become a potentially dangerous enemy.

Lucifer was cancelled by Fox following the conclusion of its third season, but was rescued at the eleventh hour by streaming giant Netflix, who will bring back the show for a 10-episode fourth season.
