It was a pretty normal after the welcoming feast . Harry Potter and his friends were going over their schedules for their sixth year . The all of the sudden the front doors to the castle burst open . Most of the students rushed out to see what the commotion is all about . A man wear what looks like expensive furs walk in to the great hall and walk up to the teachers table .

He said with a thick Hungarian accent " I seek to speak to the headmaster and the head of the lion house about a important matter ."

Albus Dumbledore and Professor Mc Gonagall stood up and took the stranger to Dumbledore's office to have their discussion . The strange took a seat in front of the headmaster's desk was waiting while Dumbledore and Mc Gonagall were out of the office .

Mc Gonagall said," Who I in the world is this gentleman and what does he what with my house ,Albus?"

"I don't know ", said Dumbledore

While this is going on Harry and this newt level potion class was being let out early,because of the half blood prince's potion book. Harry decide to go to Dumbledore's office to find out anything about the mysterious visitor that morning . He said the password to the headmaster's office ,this time the password was Chocolate Bunnies. He stood out side of the door as soon as he heard the conversation.

Mc Gonagall said ," Why do you want to speak to us ?"

" I would like to speak to you about Harry James Potter .", The stranger said with a thick accent .

Albus asked ," Why do you want to talk about Harry ?

" I want to tell him the truth ."The stranger said

Mc Gonagall asked," what truth ?"

" That his mother was kidnapped as a baby and forced to be raised away from her true family ,her customs and her traditions.", The stranger said in a raised voice
Albus asked," Who are you stranger,and how do you know such things? Because the last I check I altered every ones memory that related to her true family."

" what the heck are you talking about Albus?",asked Mc Gonagall

The stranger said ," I will answer for both you and young Harry who is out side this door right now ."

"Harry, my boy Please come in so you can meet this stranger and hear his story ." said Dumbledore in his grandfather mode.

Harry came in and took a seat inbetween the stranger and his head of house.

" I will tell you the answer to who I am and my relationship to both Lilly potter and Harry potter. ",said the stranger " I am Gellert Grindelwald ,before those to start freaking out. (He points both harry and Mc Gonagall.) I am not and never was a dark lord .(He is now pointing to Dumbledore who started to slipped back in to his seat.) He manipulated me , kidnapped my daughter ,killed my wife and has lied to my grandson."

"I FORBIDDED YOU FROM TELLING HARRY ABOUT THE TRUTH!", yelled Dumbledore
