Pansy Parkinson

Jacob immediately thinks of his fellow 7th year student, Slytherin Pansy Parkinson. She is a smug bitch, like all Slytherins, but damn is she cute.

He knows she spent most of her time in the library, so that's where he headed. Pansy is studying, and he sits next to her.

"What do you want, Gryffindor?" Pansy asks.

"I just wanted to test a spell," Jacob says.

"Ha! Fat chance!" Pansy laughs.

"Well, you are the best Slytherin I know," Jacob says, playing to her ego. "I had hoped that you would be willing to bolster your reputation by helping a fellow student out, but..."

"Okay, fine," Pansy says. "But I'm not doing this to help you. Be sure to tell Dumbledore and Snape about this."

"You have my word," Jacob says. Pansy stands up, and Jacob waves his wand.

"Mens imperium!"

Light blue sparkles surround Pansy's head, and she stands stock still, her gaze vacant and mouth slightly ajar.

"Pansy?" Jacob asks. "Can you hear me?"

"Yes Master," Pansy says.

The spell worked! Pansy is now under his control.
