You were a great teacher, you taught with great examples and experiments and you were fun. You are one of the strongest witch and of course you were more knowledgeable than other. since you were the strongest you were given many offers by Voldemort to be in his army but you rejected every time. Now, dumbledore is dead and McGonagall is suppose to be the headmistress and you are suppose to be the deputy headmistress, but Umbridge protests and wants to be the headmistress
