I just wanted to let you know you are most kind-hearted person I have ever met!
"Princess Fragrance. I am Hawk Moth. Your perfume is now your secret weapon. No one will be able to resist it, especially Prince Ali. All I want from you in exchange are Ladybug and Cat Noir's Miraculous."
—Hawk Moth
Chloé and Rose compete for the affection of the visiting Prince Ali, driving the latter to become the villainous Princess Fragrance when Chloé mocks Rose's efforts. Meanwhile, Tikki catches a cold and Marinette has to find a way to treat her.
Tropes:
- Batman Gambit: Ladybug goads a brainwashed Cat Noir to attack her with his Telescoping Staff so that it brings her right above the boat with the fireworks. Then she gets Cat Noir to catch up with her and fight him until he uses his Cataclysm power, before tripping him so that he'd fall on the control box, short-circuiting it and launching all the fireworks.
- Bitch in Sheep's Clothing: Chloé shows off her attempts at this, stealing Tikki just so she can have a unique toy to show the prince and reap the compliments on her "generous" gift to his toy drive. Fortunately the "sheep's clothing"'s thinness doesn't go unnoticed by the prince.
- Blatant Lies: Marinette claims Tikki is a rare breed of cat. Master Fu pretends to believe her.
- Brainwashed and Crazy: Princess Fragrance can brainwash anyone into serving her with her perfume. Yet again, Cat Noir ends up falling victim.
- Brought Down to Badass: Marinette spends most of episode helping out Cat Noir without her powers.
- Celeb Crush: This is the first we see of Rose's infatuation with Prince Ali. Chloé appears to also have one at first, but she just wants to reap the social benefits of being seen with royalty.
- Chekhov's Classroom: Miss Mendeliev's warning about the flammability of Rose's perfume comes in handy when Ladybug needs to stop a massive cloud of the stuff created by Princess Fragrance and happens to be near a boat loaded with fireworks.
- Chekhov's Gun: The boat filled with fireworks, established early, is used by Ladybug to clear the huge cloud of mind-controlling perfume over Paris.
- Delivery Guy Infiltration: Marinette pretends to deliver a pizza for Chloé in order to get past the doorman of the hotel where Chloé is located.
- Does This Remind You of Anything?: Princess Fragrance conducts placing a love lock on the Pont des Arts bridge with Prince Ali like a wedding. She even carries a bouquet and has Mayor Bourgeois walk her down the bridge.
- Fantasy Helmet Enforcement: Cat Noir puts a pot on Prince Ali’s head when his guardian called sliding down his pole too dangerous.
- Foreshadowing: Marinette's a little too distracted by Tikki's illness to put it together herself, but the fact that Tikki directed her to Master Fu is a strong indication that he's already in on the secret of Miraculous.
- I Kiss Your Hand: After introducing herself to Prince Ali, Chloé lays out her hand to him, expecting this. After brief confusion, he shakes it instead.
- I Need to Go Iron My Dog: Marinette's excuse for being late to chemistry is that she had to take her dog to the vet because he ate her sweater. (She and Adrien had actually been out taking care of an akuma.) Ms. Mendeliev isn't buying it. Of course, at least she showed up; one couldn't say the same for Adrien.
- Jerkass Has a Point: Though Chloé is callous about it in a way only she can be, she is correct in her instructions to block her father after Princess Fragrance spritzes him with her perfume since Princess Fragrance is after the prince and as a guest in her father's hotel and a very important person in general, his safety is paramount.
- Kick the Dog: Chloé once again; when Rose politely asks her to give Prince Ali the letter she wrote for him, Chloé pretends to be willing to do so and then laughs in poor Rose's face before ripping the letter and saying that there's no way he'd ever be interested in spending time with her.
- Laser-Guided Karma: Chloé rips up Rose's letter and mocks her for thinking that Prince Ali would want to spend time with her (not to mention stealing Tikki just to make herself look good in front of the prince). At the end of the episode, Prince Ali picks Rose over Chloé to accompany him to the children's hospital and watch the fireworks.
- Obstructive Bureaucrat: Prince Ali's guardian Soriah Khan. Even when faced with a supervillain obsessed with making the Prince her boyfriend, she insists on following his pre-planned schedule instead of running for safety.
- Offscreen Moment of Awesome: The episode starts with Ladybug and Cat Noir in front of the cameras, having just de-evilized a Magician of Misfortune who was trying to make the Eiffel Tower disappear.
- Paper-Thin Disguise: After the hotel doorman denies Marinette entry, she finds a motorcycle helmet, cape, and an old pizza box in the trash, which fools the doorman into thinking she's delivering a pizza.
- Phrase Catcher: "At your service, Princess Fragrance!"
- Princess Phase: Rose's transformation into Princess Fragrance is an evil version of this. She calls herself a princess, forces everyone to do the same with brainwashing perfume, wants to be with her Prince Charming, Ali in this case, and tries to make Paris her own kingdom with a giant cloud of perfume.
- Secret Secret-Keeper: Master Fu knows about Miraculous and recognizes Tikki as a kwami, not a "cat", but he lets Marinette believe she's kept the secret from him, since she clearly has more important things to do right now.
- Sheltered Aristocrat: In a similar vein to Adrien, Prince Ali's life is so micromanaged that even the thought of getting to see fireworks on a boat is amazing to him and he reacts to the smallest thing with delight.
- Shout-Out: Princess Fragrance is one of the many, many characters in The Book and the Sword
. She's a kind, gentle woman who's chosen as the Emperor's concubine and whose tomb starts emanating a divine smell after it's visited by a butterfly. - Sick Episode: Tikki spends the majority of the episode suffering from cold-like symptoms. She directs Marinette to Master Fu, but due to school and Princess Fragrance, they're not able to get her treated for quite some time.
- Skewed Priorities: Prince Ali's assistant worries more about the Prince's schedule than his life potentially being in danger.
- Three-Point Landing: Ladybug after Cat knocks her back.
- Verbal Tic: All of Princess Fragrance's victims sing their lines.
- Wham Line: Marinette asks Master Fu how he healed Tikki, and he says it's an "Ancient Chinese secret". Only after she's left does he add "...just like yours", making it clear that he knew all along exactly why she came to him.
- Working Through the Cold: After Marinette finally finds Tikki in Prince Ali's car, Tikki says there's no time to go to the healer and she'll be okay... but Marinette insists on getting her treated first, not wanting to repeat her earlier mistake after delaying Tikki's treatment for school.
