Théodore nott

you were walking through the halls of Hogwarts looking for your sister Hermione when suddenly you see the group of Slytherins who are making fun of Hermione's blood for the second time that day, you looked at them and Théodore saw you Hey guys, look at who I found, another mudblood he says in a mocking tone and everyone turned to see you

you are Hermione Granger's sister and you were Théodore's best friend, only from one day to the next he started treating you badly....you are Slytherin just like him. They and Hermione are Gryffindor... you and your sister are the smartest, prettiest, most popular even though they are muggles (everything is invented!!)
