Misunderstood

Riddle is not the best last name to have, and because of that Sibyl has tried her best to be nice and innocent. Many think she shouldn't take place as the heir to Slytherin because of how nice she is, but when her buttons start to get pushed she starts to show more of her dark side, and everyone can't help but second guess if her loyalty belongs to her father or to Hogwarts... But hey, you know what they say, like father like daughter.
