In Hawk Moth's lair...
"I feel a blonde girl whose request for an apology has been denied," the window to his lair opens, ready to create another supervillain. "Such feeling for this denial makes her the perfect prey for my akuma."
A butterfly lands on the palm of his hand, and he covers it with his other hand to fill it with dark energy. This process turns the butterfly into an akuma, and he lets go of it.
"Fly away, my little akuma, and evilize her."
The akuma flies away from the lair and went into a bar at Mystic Falls. It enters itself into Caroline's necklace, causing a moth-shaped emblem to appear on her face.
"Apologizer, I am Hawk Moth," Hawk Moth communicates with her. "Your vampiric friend has denied your request for an apology, but I'm here to change all that. You will have the power to force someone like her to apologize. In return, give me Ladybug's earrings and Cat Noir's ring and send my apology to them. After all, it's nothing personal."
"I'd happy to accept our little deal, Hawk Moth," Caroline accepted the deal.
As a result, black smoke appears from her necklace to cover her entire body. And once it disappears, she now has the appearance of a purple-skinned woman wearing a sexy outfit.
"Caroline?" Elena asked with concern on her face.
"Call me Apologizer, and you will apologize to me right now," Apologizer fires a yellow beam from her right index finger and that changes Elena's behavior from repressive to apologetic.
"I'm sorry, Apologizer! I'm so sorry for everything I did to you while my humanity was turned off!" the brunette vampire apologized.
"Now that's the spirit," the akuma said with satisfaction on her face and feels stronger from this.
"Good. It won't be long now until Ladybug and Cat Noir show up and give me their apologies for ruining my plans to steal their Miraculous," Hawk Moth said with satisfaction on his face before laughing evilly. "Mwa ha ha ha ha ha ha!"
