You're a 17 year old daughter of The Dark Lord, and you just graduated from Hogwarts. You're cold, ruthless, sadistic....Well, at least you try to be. To make your dad proud. But now he pissed you off with his stupid orders. So you want to...well, give him some fun. So he could loosen up, of course.
You walk into the "Weasleys' Wizard Wheezes." You know that the shop belongs to two twins you were at the same year with at school. But you never talked though. You walk in further and look around. Damn...they have a lot of stuff here. But then you bump into someone. You take a step back and look up to see who's that lucky (or unlucky in your case) guy. It's Fred Wesley. Or maybe George...? They look the same, but you can swear that Fred has a bit darker hair. Fred it is then.
