With Charlotte Richards dead and Amenadiel having taken her to Heaven himself, it's up to Lucifer, Chloe and Dan to settle the sole piece of business that remains: find her killer and bring them to justice, once and for all.
Tropes present in this episode include:
- Bait-and-Switch: After Dan tells Ella the plan to deceive Pierce, it seems that she goes to him to warn him of the plot, out of her admiration of Pierce. The next scene reveals that the plan — deceiving his mook to assassinate Dan — works perfectly, and Ella is later seen in Lux's penthouse, where Chloe congratulates her for switching sides.
- Brain Bleach: Chloe chastises Lucifer for not revealing that Pierce is Sinnerman sooner, considering what happened between them just three episodes earlier.Chloe: I mean, I almost married him!
- Break-Up/Make-Up Scenario: While not romantically involved with each other, Mazikeen's capture - and her subsequent escape - finally leads her to reconcile things with Linda over the subject of Amenadiel.
- Big Bad: Being the Sinnerman and now having (accidentally) killed Charlotte Richards while trying to kill Amenadiel, Pierce/Cain finally fully falls into his role as the season's Big Bad.
- Bulletproof Vest: Chloe, thankfully, is wearing one when she and Lucifer walk into a trap.
- Cassandra Truth: When Lucifer reveals that Pierce is the Sinnerman, a shocked Chloe asks why he didn't tell her this. Lucifer reminds her that he did tell her, but Chloe asks why she would believe him about Pierce being the world's first murderer.
- Cliffhanger: The episode ends in a massive one, with Chloe finally realizing that Lucifer really is the Devil. She gasps that "It's all true" ...and roll credits. note
- Crisis of Faith: Charlotte's death makes Ella question her faith in God, symbolized by her taking out her cross necklace.
- Curb-Stomp Battle: Lucifer delivers one to Cain, after effortlessly taking down all of his mooks. He dodges all of Cain's attacks with ease, except one, quipping and adjusting his suit as he does so.
- Curb-Stomp Cushion: Cain manages to get in one, count it, one glancing hit on Lucifer in their fight, causing a gash in his sleeve (and possibly the skin beneath). This is the only hint that Cain is not completely outclassed, just very nearly so.
- Drama-Preserving Handicap: Having found Mazikeen's hell-forged karambit earlier in the episode, Pierce actually has an equaliser in his fight against Lucifer. Not that it actually does him much good in the end.
- Eyes Never Lie: Ella didn't believe Dan's story about Pierce being the Sinnerman at first; it was the look in Pierce's eyes when she handed him that phone that convinced her he really is a murderer.
- Heartbroken Badass: Dan's grief over Charlotte's death only makes him more dangerous, as one of Cain's henchmen discovers.
- I Am What I Am: A sad example, and possibly foreshadowing for Lucifer's own backsliding at the end— when Dan is interrogating the Sinnerman mook, he says that while he resented Pierce for calling him a Dirty Cop, he really has done and is capable of some pretty awful things, and killing someone who tried to kill him in his sleep wouldn't be a problem for him. Note here that Dan has spent two seasons trying (and for the most part succeeding) to be a better man.
- Incriminating Indifference: Inverted. Chloe realizes that Pierce is the killer precisely because he acts too emotional.
- Internal Reveal: After three seasons of not believing his "metaphors", the Detective finally gets to see the Devil behind the eccentric night club owner/police consultant. Leads to the Wham Line below.
- I Will Find You: A threatening example, Chloe vows in their phone call that she will come find Pierce to put him to justice.
- Ludicrous Precision: When Mazikeen gets to Linda's office, the therapist comments on the demon's bloodied, exhausted state. Sure enough, Maze is still the boastful demon she always is.Linda: You look like you fought ten people and ran a mile to get here.
Mazikeen: Twelve people. [beat] ...and four miles. - Never My Fault: Lucifer's reaction when Chloe chews him out for not telling her about Pierce being the Sinnerman is to remind her that he did warn her, but she blew him off.
- Nonchalant Dodge: Lucifer dodges nearly all of Pierce's knife swipes and even taunts him by straightening out his jacket.
- No-Sell: Thanks to Chloe being far enough away, Lucifer's able to no-sell the bullets from Pierce/Cain's gun.
- O.O.C. Is Serious Business: Chloe doesn't believe that Pierce is the Sinnerman until she sees him tearfully proclaiming that he will do everything he can to catch Charlotte's killer.Chloe: Pierce doesn't get emotional; not like this. (beat) He really did it, didn't he?
- Put on a Bus: Amenadiel is completely absent in this episode. Lucifer speculates that, having regained his wings, he probably doesn't have any more reason to stay on Earth.
- Pyrrhic Victory: Lucifer saved Chloe and defeated Pierce. And in the process, he became so filled with hate that he lost the self-forgiveness he'd earned, starting to see himself as a monster again. Pierce dies laughing, knowing that while he is damned, Lucifer is as well.
- Right for the Wrong Reasons: Dan learns that Charlotte was investigating Pierce for being the Sinnerman, and concludes that he killed her to shut her up. He's right that Pierce was the killer, but completely wrong about the motive— in fact, Pierce never even knew that Charlotte was on to him.
- Roaring Rampage of Rescue:
- Still under the belief that Linda's in danger thanks to the previous episode, Mazikeen fights her way out of captivity and storms her way back to Linda's office, leading to her finally burying the hatchet.
- It took three seasons, but Lucifer finally went into a fight - albeit against a group of mortal mooks - with something approaching his full divine power. Busting through a penthouse's bay window, bloody wings fully unfurled, and proceeding to effortlessly beat them all down. It then culminates in his "fair fight" at the end of the episode.
- Roaring Rampage of Revenge: Dan will stop at nothing to bring the man who killed the woman he loved to justice.
- Super-Strength: Pierce may be a buff, heavily-built man, but he's a mortal, while Lucifer is a full-blown angel. He demonstrates this by effortlessly snapping Pierce's wrist and stabbing him with his own knife.
- This Is Going to Suck: Maze has a brief look of this when she sees that there are more of Pierce's goons for her to fight. She still beats the crap out of them.
- Title Drop: Just like every other episode in Lucifer bar the pilot, the episode's name is dropped in the spoken dialogue.Lucifer: Now, I promised you... that I would find a way to kill you. And I am a Devil of my word!!
- Wham Line: "It's all true."
- Wham Shot: The final shot of the episode (and, if fan-fueled renewal/migration efforts hadn't borne fruit, the entire show): Lucifer Morningstar, his "devil face" once again in full effect, Chloe standing before him utterly dumbfounded... and Marcus Pierce/Cain finally lying dead in the foreground.
- What the Hell, Hero?: Both Chloe and Dan chew Lucifer out for not telling them that Pierce is the Sinnerman. Lucifer retorts that he tried to warn Chloe, but she didn't believe him.
- Wing Shield: When Pierce's goons begin shooting at Lucifer and Chloe, the former unfurls his wings to protect them both. However, since Chloe is nearby, the bullets damage the wings, causing them to bleed horribly until he manages to muster the strength to Flash Step outside the building.
- Worf Had the Flu: Throughout the whole episode Maze continues to recover from the drug she was injected, so she cannot fight to her full capabilities. She is still able to beat twelve people and run four miles.
