SPOILER WARNING: This article contains spoilers for Lucifer Season 6, now streaming on Netflix.

Although the series may be called Lucifer, Luci-fans have always known that the show is really about the devil and Chloe Decker's seemingly ill-fated romantic relationship. For six seasons, the duo faced everything from a wrath-fueled Celestial twin brother to processing the sudden and tragic loss of Chloe's ex-husband, Detective Dan. Season 5's finale even saw the couple beat death to find their way back to each other. However, that experience only shook Lucifer to his core in Season 6. Having lost her once, he becomes terrified that it'll happen again.

During an interview with CBR, Ellis shared how Lucifer's immortality -- whether he liked it or not -- has always been something that keeps him from growing closer to Chloe. However, Season 6 finally confronts this fear of his, and Chloe's own fear of dying again, head-on.

"The thing with Chloe and Lucifer is one of them has always been ready and the other hasn't," Ellis shared. "They've always been just missing each other in terms of where they're at. [In Season 6], We find them cemented in their feelings for each other. They know they want to be together."

However, even if the duo survived a literal battle between heaven and hell, the end of Season 5 left many things up and the air in the duo's professional and personal lives. "Lucifer is no longer the Devil and Chloe doesn't work for the LAPD anymore," he continued. "So, what is their point in the world? What are they here for?"

Ultimately, Season 6 explored the aftermath of having Chloe die and leans into showing how that experience has changed her, and, along with it, forced Lucifer to face what loving a mortal really means. "The big elephant in the room, that they've never really talked about, is the fact that Lucifer is immortal, and Chloe isn't," Ellis said. "What does that mean for our characters' future? That's what they are faced with in this season."

As the saying goes, having a child changes everything, and Lucifer and Chloe prove that they're no exception to the rule. "Of course, with the introduction of our new character Rory, they are forced to think about the future in a way they never thought they would have to think about," Ellis shared, highlighting that their daughter helped lead them back to each other.

All six seasons of Lucifer are streaming now on Netflix.
