Disclaimer I don't own Harry Potter.
Boom.
The whole shack shocked and Harry sat up bolts upright, staring at the door.
Boom. They knocked again. This time waking up the Dursley's up. Uncle Vernon came downstairs with a rifle in hand "Who's there?" Vernon shouted.
Then there was a pause. Then a smash!
The door was hit with such force that it swung clean off.
A tall, skinny man with black hair, dressed in all black robes was standing in the doorway. "Its rude to keep someone waiting." the man said in a cold tone.
Petunia looked at the man with bigs eyes and slight fear "You!? You... are that dirty awful boy." Petunia said.
The man looked at Petunia with disgust "Hello, Petunia its lovely to see you again as well." he said with a cold bitter tone the same as Petunia "You shouldn't be surprise about this Mr. Potter is going there as well." he said as walks inside and takes a seat.
Uncle Vernon walks over to the couch aiming the rifle at the man's face "I demand that you leave at once, sir! You are breaking and entering!" Vernon shouted at the man who wasn't looking at him but at Harry Potter. "Last chance sir, I swear it." Vernon said putting his finger on the trigger.
The man looks up at Vernon "rat." he said as the Dursley's scream in terror as Vernon's rifle turned into rat and is throw across the room. The man then turns his attention to Harry Potter looking a little concern on the inside but not showing it on his face, the boy is to skinny wearing clothes way to big for him but the other child is fat with perfectly fitted clothes "Mr. Potter I have something for you." he said taking out a letter from his pocket and hands it to the child.
Harry happily takes the letter and reads it at loud to himself, getting more confused after finishing it, first a school of magic? Who is this man and how does he know Aunt Petunia. "Sorry, but who are you?" Harry said.
"Professor Severus Snape, potion's master and head of Slytherin house at Hogwarts." Snape said taking back at the boy polite matters.
Vernon came between the two of them jamming his finger into Snape's chest while holding Harry back by twisting his arm "He's not going, we swore when we took him we'd stop it" he said as Harry yelps in some pain.
Snape pulls at a wand aiming it at Vernon's throat. "First things first, let go of the boy and don't you ever lay a finger on him. Secondly you have little to no power to stop him, and lastly get your sweaty, filthy fingers off me unless you need another demonstration of my power." he shouted making Vernon back away in terror.
"You, knew? All along you knew?" Harry said.
"Knew, of course we knew. You would be freak the same as your mother and father and this God awful man all a bunch of freaks." Petunia said.
Snape fuelling with rage marches over to Petunia and aims his wand at her throat "Don't you ever insult Lily in front of me." Snape said fuelling with more rage then Harry has ever see in Vernon.
"Your pathetic." Petunia said in fear struggling to talk.
"excuse me?" Snape said.
"Your hear me pathetic, your still holding on to her its pathetic. She just befriended you because of pity, and threw you way after a better option came around not that I can blame her, James is also a freak but he's far better looking then you. She broken you little black heart and you still honor her memory its pathetic." Petunia said.
Harry and the Dursley's looked up in shocked, Snape looks like the kind of person you didn't wanted to make angry, and a few seconds later Petunia followed by Vernon and Dudley were frozen solid. "Sorry about that, don't you worry about them it will wear off in a hour. So Mr. Potter or you coming or not." Snape said looking down at Harry who nods up at him.
