What if Hawk Moth used the opportunity when Chat Noir was under the control of Princess Fragrance to get more information?
The Princess and the Peek
Chapter 1: The Peek Beneath the Mask
Prince Ali, his chaperone, Chat Noir, and the fish-smelling Chloé Bourgeois were all in the Prince's car, driving fast to escape from Princess Fragrance (the akumatized Rose Lavillant) who had set her sights on making the Prince her own.
Chat said, "Can we open the windows? This fish smell's even too much for a cat."
The chaperone, in the driver's seat, pushed buttons to roll down the windows. Chat Noir and the Prince stuck their heads out and gasped for fresh air.
Tikki sneezed from Prince Ali's pocket. Ali looked to see where the noise came from. Tikki was back to posing as a stuffed animal (just like when Chloé gave her to Ali as a present for the children he was going to visit in the hospital).
"We have precisely nine minutes to get to the hospital," said the chaperone. "The prince is on a very strict schedule."
"What?" said Chat Noir. "No way we're going to the hospital now! We have to get Prince Ali out of Paris ASAP!"
There was a thump on the roof. It was Princess Fragrance, who had used her perfume spray like a jet to catch up to them.
"My prince! Fancy meeting you here. What a stroke of luck!"
"The windows!" Chat warned the chaperone.
The chaperone tried to close all the windows, but the akuma held open the sunroof.
"My prince, I'll take you to the Pont des Arts," said Princess Fragrance. "And there, we'll seal our love!"
She fired in a blast of perfume, taking control of everyone in the car. (All but one. Tikki wriggled free from the Prince's pocket and slipped to the floor under the cover of the perfume cloud. Kwamis don't need to breathe.)
Hawk Moth laughed in his lair. "Cat Noir is down! It won't be long before Ladybug shows up too and meets her doom!"
This was perfect! Hawk Moth had absolute control over Chat Noir through Princess Fragrance. He could make him give up his Miraculous. He could even cause him to commit suicide.
Neither of those options made sense at the moment. He still needed to get Ladybug's Miraculous, and Chat Noir would be the most powerful weapon against her. But there was something else he could do. He could force Chat Noir to give him information.
Using his telepathic connection to his victim, Hawk Moth sent, "Princess Fragrance, please ask Chat Noir the real name of Ladybug."
"Tell me Ladybug's real name," the Princess commanded Chat.
"At your service Princess Fragrance," sang Chat Noir. "I am sorry, but I have no clue what her real name is."
Hawk Moth sent, "Then ask him for his own name."
"What's your real name?" asked the Princess.
"My real name is Adrien Agreste, my Princess," sang Chat Noir.
Hawk Moth could not believe it. His own son? His enemy had been under his roof the whole time?
"I want to be sure," sent Hawk Moth. "Ask him to remove his ring."
She did so.
"At your service Princess Fragrance," sang Chat Noir again as he obeyed.
Chat Noir detransformed. It was Adrien!
"Ask him to put his ring back on and transform again," said Hawk Moth.
"I'm getting disturbed by all these requests, Hawk Moth. I want to set up my wedding with my Prince!"
"It's all I need except for one more thing, then I won't bother you anymore. Please tell Chat Noir that when he fights Ladybug he must not use his Cataclysm."
Adrian would never forgive him if he was forced to kill in his father's name. He could certainly overpower his partner and get the earrings without resorting to that ultimate power.
Princess Fragrance sighed and did as Hawk Moth asked. Then she began jetting her subjects one by one from the car to the Pont des Arts to get her wedding under way.
Tikki waited on the floor, unnoticed. She was feeling too sick to fly away and look for Marinette.
Marinette finally found the abandoned car after searching for quite a while on a scooter. Other cars were crashed and abandoned around it. Marinette still had the helmet she had used as a disguise while fighting Princess Fragrance at the hotel.
"Oh no! Where's Tikki?"
She pulled off the helmet and ran to the car.
"Tikki! Tikki?"
There was Tikki on the floor of the car with her eyes closed, looking weak and sick.
"Tikki, I was so worried!" said Marinette, picking up the kwami.
"Marinette..." said Tikki.
"And you're much worse than I thought! We need to get you help!"
Tikki said, "We don't have time. You have to transform. I'll be okay..."
Tikki coughed weakly.
"No, Tikki. I'm not making the same mistake twice! We have to get you to the healer now!"
After the healing session at Master Fu's, Marinette walked along the bank of the Seine with Tikki in her cupped hands.
"Tikki, I'm so, so sorry. You're so sick and, well, I don't know what I do without you."
"You wouldn't be Ladybug for one!" said Tikki with a giggle.
"I know, but I mean – Tikki, you're more than just my kwami for me."
"I know," said Tikki, flying up and hugging Marinette's cheek. Both of them laughed.
"Oh, the Pont des Arts bridge! That's where they're headed! I overheard it in the car. Hurry, there's no time to lose!"
Marinette got set to invoke the transformation.
"One thing you have to know before you transform," said Tikki. "Hawk Moth made Chat Noir reveal his secret identity. He's Adrien Agreste!"
"No, Chat Noir can't be... can he?"
"He is. Princess Fragrance made him destransform for a minute. He's going to be guarding her."
"Then I have to fight the guy I love," said Marinette. "Tikki, spots on!"
