I hope this letter finds you well, as that is all about to change. You know what you did and I know what you did. Pretty soon everyone will know what you did. Lovely, no?
You can deny it if you wish, but your record is against you. Your target is now half-deaf. His semi-pro Quidditch career has, in all likelihood, been ruined. Because of you. Do you honestly think anyone could ever love someone who did that to them?
I thought you ought to know that, while some of the effects of your little scheme were disastrous, not all of them were. He admitted his love for me in the hospital while recovering from self-inflicted injuries. Does that make you jealous? It should. Because you'll never have that. Not from him.
Now, I happen to think this form of payback is quite mild. I thought of other methods to deal with you, but decided they were too harsh. Hopefully you will not need further reminding of your idiocy.
Please keep in mind that feeding someone a potion against their will or without their consent is a crime.
Respectfully, PRC
PS: I imagine your face must be burning about now. Am I right?
[Parchment is hexed with a spell taken straight out of Hermione's book of tricks. Boils across Romilda's face spell the word "DESPERATE" - "des" on the forehead, "per" across her cheeks and nose, and "ate" across her chin. Unlike Hermione's spell, however, the spots are only visible to Romilda and Penny (not that she would know this at first). They will fade in a week.]
