Send Cardin away and erase his memory

Roman may be a terrible person, by his own admission, but he certainly was not a pervert. Nor was he a voyeur. He was not going to watch these teenagers having sex with each other.

However, he hadn't got the most out of Blake or that other girl yet.

Writing into the book once again;

CARDIN WILL GO BACK TO THE CAFETERIA AND WILL FORGET ALL ABOUT THE LAST HALF-HOUR.

Cardin didn't teleport away like intended but he did leave the room without a word or concern. The girls had just taken his belt off, though, so Roman imagined he was going to get some laughs when he returned to the cafeteria with his pants around his ankles.

"Cardin! Where are you going?" Velvet called, pouting a bit.

"Don't worry," Roman said, revealing himself to the two girls, "there's still fun to be had with me."

"Hello, Mr. Torchwick," Blake waved from where she sat on the knees.

Velvet whispered to her, "Isn't he a criminal?"

Blake just muttered back, "What does that matter? He's still a human and we're just empty-headed mongrels that need to be trained. We don't need to think about his criminal history, Vel."

Velvet couldn't disagree with Blake there.

"Excellent. I knew it was a good idea to follow you, kittycat. You're so much more fun when you know how to behave."

Time to get creative.
