Pansy Parkinson

Pansy was a pretty awful person all around, really besides being reasonably pretty with a great arse the only other positive Luna could think of the Slytherin was that she was smart enough to not yell her racism to the sky after her side lost the war. And that was damning with faint praised.

So Luna had decided to turn Pansy into her own personal toy.

In all honesty not much thought had went into the decision, Luna had simple seen Pansy at Hogwarts one day, still trying to act high-and-mighty despite no one buying it, and decided it was the best use of such a worthless girl to become a toy.

Luna didn't really even think about the how to much, Pansy was on shaky ground as is, an open supporter of Voldemort that had tried to sell out Harry Potter? 1 sentence from Luna to Harry and Pansy would be thrown into Azkaban no questions asked.
