Lucifer and Chloe investigate the death of an internet artist, but soon discover that this is just the first of a string of murders that will bring Father Kinley's prophecy to realization.
Tropes present in the episode include:
- Act of True Love: Realizing that as long as the demons of Hell are in rebellion, his loved ones will never be safe, Lucifer decides to return to Hell and retake his rightful place as King. The selflessness of this act is what turns his divine form back to normal, indicated by the snow-white, feathered wings he uses to fly back to Hell.
- Anguished Declaration of Love: Chloe makes one to Lucifer to convince him to stay after he decides to return to Hell. While he appreciates it and returns her feelings, all it does is reaffirm his decision to return in order to protect her.
- Artistic License – Gun Safety: Chloe's bad about this (as usual). She empties a clip into a demon with Eve and baby Charlie standing almost directly behind it. If she took a single step to the right she'd have a clear line of fire.
- As Long as There Is Evil: Or in this case, the absence of one. As long as the throne of Hell is vacant, demons will always try to return to Earth to endanger humanity.
- The Big Damn Kiss: Lucifer and Chloe have a heartwrenching one at the end.
- Bittersweet Ending: Charlie is rescued, but Lucifer is forced to return to Hell, leaving Chloe devastated.
- Cassandra Truth: Invoked when Chloe suggests telling Dan and Ella the truth about the demons so they know what they're really dealing with. Lucifer points out that he's spent the last three years being completely up front on how he's the Devil and they don't believe him. The only way to prove it would be showing his real face, and Chloe knows first-hand how badly that can go.
- Character Development:
- Lucifer in Season One would never have willingly gone to reign in Hell if those he cared about were in danger. The fact that he's doing it to protect everyone shows.
- Amenadiel also gets some, showing how far he’s come by staying on Earth with Linda and baby Charlie.
- Eve, having spent the last few episodes pining after Lucifer and attempting increasingly dumb ways to win him back, realises that her obsession and selfishness is not just destructive, but also misplaced, and she should look for love in people who actually want her. In the end, she moves on from Lucifer and decides to try and figure out who she is outside of a relationship.
- Combat Stilettos: Eve almost always wears heels when she's out and aboutnote , and although "combat" might be a bit of a stretch, she does use them to kill a demon-possessed woman by bringing her heel down hard on her eye.
- Cool Chair: As shown in the ending, Lucifer's throne in Hell towers over everything else in the realm, giving him a clear look at the whole place. It looks like a skyscraper that's as tall as the rest of the place is wide.
- Demonic Possession: Requires a recently dead body, and it's mentioned Lucifer banned the practice before leaving Hell. But Dromos and his friends don't particularly care about that law.
- Didn't Think This Through: Eve learns the hard way that it may not have been the best idea to try and trust some demons from Hell to keep their word about following her plan.
- Easily Forgiven: Linda was upset and Maze was furious when Amenadiel admits he was thinking about taking Charlie to Heaven, even though he never went through with it, but they still immediately forgave him for it. Somewhat justified, as the real kidnapping shows that his temptation to move back to the Silver City wasn't exactly unjustified; Earth isn't the safest place to raise an angel. There's also no time to be angry when their son isn't safe yet.
- Everyone Has Standards:
- Even after all his Character Development, Lucifer can be very self-centered at times, especially when it comes to things that may impinge upon his freedom. However, the idea of his baby nephew Charlie being forced to replace him as King of Hell horrifies and enrages him. Preventing something like this from happening again is one of the reasons why he returns to Hell at the end.
- Similarly, it takes finding out that the demons have kidnapped Charlie for Eve to realize how badly she screwed up by summoning them in the first place.
- The Friend Nobody Likes: Squee, apparently. Maze claims that nobody likes him.
- Heel–Faith Turn: Ella regains her faith in God, realizing she shouldn't expect God to fix all of humanity's problems but to encourage them to fix them on their own.
- Hell Has New Management: Invoked by Dromos, who plots to have baby Charlie replace Lucifer as the King of Hell. Seeing as Charlie is a baby, however, he'll need a regent, and Dromos is glad to make the sacrifice.
- Hidden Depths: Despite no longer believing in God, Ella admits that she missed praying for him. She was just so angry since Charlotte's murder. Also, Dromos - a genuine demon and native denizen of Hell, a son of Lilith who spends his days "popping eyeballs" with a smile on his face - actually knows how to properly treat a baby, and does so with Charlie while he has him. Although his intentions are malicious, he doesn't seem to take any shortcuts in regards to Charlie's care, and even chides another demon for heating up his milk too much.
- Idiot Ball: Chloe takes the ball and runs with it during the climax of the episode. Demonic Possession is running rampant, Eve is carrying around baby Charlie alone and unarmed, and Chloe is now aware that she's the cause of Lucifer's mortality, but somehow that seems like the perfect time to try making an Anguished Declaration of Love. Fortunately, Lucifer's devil form gets them out of the situation when the good guys inevitably face a Zerg Rush at the worst possible time.
- Imagine Spot: To show Lucifer's improved mental state after the breakdown in the last two episodes, he seemingly imagines the precinct having a complex, well-orchestrated dance number, which includes Dan leaping into his arms.
- It Seemed Like a Good Idea at the Time: Eve explains that, at the time, when she had just killed Father Kinley in self-defense, it seemed like a good idea to also summon a demon to possess his body. This is because he was clearly going to hell, and she'd previously made plans with Kinley to send a "messenger" down there to tell the demons to come get their king. However, she quickly realizes that Dromos and his friends are too much to handle.
- Journey to Find Oneself: Eve parts ways with Maze at the end, feeling that she has too many things on her mind and needs to think about her place in the world before she can properly start a relationship.
- Kneel Before Zod: When the demons surround the team, Lucifer takes his demonic form and loudly commands the demons to bow down before him, at which point they comply (if grudgingly on Dromos' part).
- Loophole Abuse: Only a celestial being can rule Hell. It's synonymous with saying that only Lucifer can rule Hell, as the other angels refuse to take his place. The demons get around it by trying to make the half-angel Charlie the King of Hell, since, as a newborn, he's not in any position to refuse, and Dromos can effectively rule by raising Charlie into what he pleases.
- Mayincatec: While trying to recall the place where the demons are hiding, Eve recalls that it's based on a pre-Columbian civilization and speculates "Aztec" or "Inca", before Chloe correctly deduces that it is "The Mayan".
- Missing Child: Linda wakes up from her nap to find baby Charlie is missing and Amenadiel didn't take him. The night nurse was replaced by an impostor working for Dromos who now has the baby.
- My God, What Have I Done?: Eve is utterly distraught when she realizes that her summoning Dromos and setting him to get Lucifer led to Charlie being kidnapped, tearfully telling Chloe and Lucifer that she didn't mean for anyone to get hurt, and especially not a little baby.
- Power Makes Your Voice Deep: When he transforms into his devil form at the end, Lucifer has an extremely deep, guttural voice. Notable since when he showed his form to Chloe in the previous episode, he still had a normal voice.
- Prophecy Twist:
- Chloe realizes that Kinley's prophecy about "evil roaming the Earth" is not about Lucifer at all, but rather demons who continuously multiply their population on Earth by killing humans, allowing more demons to possess them.
- Chloe is Lucifer's first love and their meeting does indeed herald evil coming to Earth, because it caused a string of events that eventually led to Eve making a deal with demons to possess dead humans.
- Rightful King Returns: The only way to permanently stop the rebellion in Hell and settle everything is for Hell's true ruler to return and rule it. So Lucifer retakes his throne.
- Rule of Symbolism: When Lucifer says goodbye to Chloe at the end, sacrificing his happiness to save the people he loves, it is revealed that he has regained his pristine-white angel wings.
- Series Fauxnale: It's the first season that doesn't end on a cliffhanger and in fact could work as a Bittersweet Ending with Lucifer saving the day but having to return in Hell and leave Chloe forever.
- Slouch of Villainy: Maybe not a villain, but the shot of Lucifer sitting on his throne at Hell shows him slouching over and looking very bored, justified since he has returned to a place he hates so much.
- Suddenly Shouting: Dromos screams at Eve to "STOP TALKING!!" when she tries to order him around.
- Tempting Fate: Lucifer assures Chloe that she won't see "anything monstrous ever again". They are being watched by Kinley and DJ Holla Bee possessed by demons.
- Title Drop: As is typical for the show, but unusually, not quite verbatim; addressing Charlie, Dromos instead says "who da new king of Hell".
- What the Hell, Hero?: Both Lucifer and Chloe give a well-deserved verbal beatdown to Eve for summoning a demon to possess Father Kinley.
- Zombie Apocalypse: In the climax, it is revealed that demons have killed dozens if not hundreds of people in Los Angeles to create room for vessels. They overwhelm the heroes at the Mayan, forcing Lucifer to retake his throne to stop them.
