Professor Snape: You were seen! By no less than seven Muggles! Do you have any idea how serious this is? You have risked the exposure of our world! Not to mention the damage you inflicted on Whomping Willow, that's been on these grounds since before you were born! Ron: Honestly, Professor Snape, I think it did more damage to us. Professor Snape: Silence! I assure you that were you in Slytherin and your fate rested with me, the both of you would be on the train home TONIGHT!
