Cleanser burst into the classroom, startling Ms Bustier and the students, all of whom jumped out of their seats.

Ms Bustier stood up and protectively held up her arm, crying out,
"Who are you and what do you want?"

The villain responded with an evil cackle,
"I am Cleanser and I want Chloe!"

Then he brushed the sweet teachers face with his broom bristles, and she immediately dropped to the floor, before looking up and saying
"Yes Cleanser".

A general outcry of alarm arose at this, but they were trapped, unable to escape out of the classroom because Cleanser was right next to the door.
Unable to think of anything else, many of the students dove under their desks, terrified, hoping that Ladybug and Chat Noir would show up soon...

Cleanser looked around the classroom but couldn't see Chloe, as she was among those that had hidden under their desks. He called out in an almost sing-song voice,
"Oh Chloe... Where are you?" Then he snarled,
"You little brat! Lets see how you like to be looked down on and do demeaning tasks!"

"Bernard?" Marinette quietly whispered to herself, quickly connecting the dots.

Chloe stuck her head up from behind her desk and gave a little whimper. Cleanser immediately turned at the noise, and, seeing her, gives a wicked smirk, beckoning her.
"There you are. Come here Chloe! I have a surprise for you"
Chloe, like her normal ignorant self, gives a squeal,
"A present? For Moi? Well..." and she got out from under the desk and walked towards Cleanser.

Marinette stood up and cried,
"Don't do it Chloe, it's a trick!"
Chloe just laughed in response,
"Stupid Dupain-Chang! He is just another one of my devoted fans".

Marinette exclaimed with a frustrated groan and buried her head in her hands. She looked around, trying to find a way to get out of the classroom without being spotted, so that she could transform.

"Listen to Marinette, Chloe!" yelled Adrien, but it was too late.

Chloe, now standing before Cleanser (who had moved away from the door and was now at Ms Bustier's desk) puts out her hand, palm up, and demands,
"Well?" Whilst doing a 'gimme' gesture with her hand.

Cleanser just smirked and lifted up his broom, sweeping the bristles against Chloe's face.
Chloe dropped to her knees and looked up at Cleanser,
"Yes Master?"

"Noooo!" Cry out Adrien and Marinette, whilst everyone else gasped with shock and at once, with exclamations of alarm, began to rush for the door.

Marinette and Adrien, though both desperate to escape so that they could Transform (and both still oblivious to each others identity), stayed behind and helped everyone else to evacuate first
"Go, go, go!" They said, shoving people out the door.

Cleanser relished the pathetic panic and terror of everyone, occasionally flinging out his broom and stopping a dozen or so in their path, who immediately dropped to their knees.
Others managed to dodge his bad broom and escape. But no matter. They may run, but he knew he would catch up to them and control them all!

But first... he leant down and whispered into Chloe's ear with a slight chuckle,
"You always looked down on me, but that will now change... now you will look up to me and worship the very ground I walk you!"
"Yes of course Master! You are the most amazing person I am scum compared to you!" Chloe whispered in a shrill voice
"Good..." Cleanser raised his hand in victory, before pointing to her desk and saying
"I want you to go and clean off every single scrap of gum off your desk. And once that is done you can go and do all the other desk. Every. Single. One. In the school!"
"Yes yes" replied Chloe with a bow, and then rushed off to complete her task.

Almost everyone was out of the classroom, until only Marinette and Adrien were left.
Adrien looked at Marinette and said,
"Go! I'll be right behind you!" Marinette glanced back and started as she saw Cleanser advancing, broom in hand. She turn to Adrien, the love of her life, and managed to squeak out
"N-no! You go and hide with the others, I will join you soon".

Adrien didn't like it, but he knew that, the sooner he transformed into Chat Noir, the better.
He turned and dived out of the doorway, just in time, oblivious to the fact that he had left his lady behind him...

Marinette turned to see Cleanser, twirling his broom, right behind her. He glared with anger at the girl who had let everyone else get away. As he stalked towards her, she took a step back and stumbled. Falling against the wall. There was no escape. She cried out,
"Please Bernard... don't do this!" Then she lifted her arms above her head in a protective gesture and tightly closed her eyes.

Cleanser stopped short as he recognised her, the memories of her kindness to him stirring like embers in a fire.
After waiting a few tense moments, only to find no bristles brushed against her, Marinette slowly put down her arms and opened her eyes. Cleanser was looking down at her, his expression softened.

He said gently,
"You are the only one who was kind to me Marinette. Go! Before I change my mind!"
Marinette sprung to her feet and ran away fast as she could.
