A.N- You see Harry could tell the Winchesters about the Wizarding world because they are aware of some of the supernatural beings. Also it goes with canon except that they don't have death's ring.

     As soon as I got there, I saw Dean Winchester in the 1967 Chevrolet Impala with a boy who is in the passenger seat and looks to be seventeen years old with blue eyes that have specks of brown in them, golden skin, hair that is so black that when light shines upon it looks midnight blue. The kid stood at 6' high and 3". I then realized that right in front of me is my long lost son Harriel, my heir and my own flesh and blood.

" H-harriel is that really you?" I asked what I hoped to be my son.

"Yeah it's really me dad." The kid now known as my son said with tears in his eyes.

" Wait did you just say Dad?" Dean screamed aloud.

"Yes I did say that. You see I'm Harry Potter in the Wizarding world, but was born as Harriel the archangel of life and death. Also everyone in the Wizarding world betrayed me except for eleven people. Just because I've been betrayed doesn't give you and mom the right to destroy both worlds. Also where is Papa? I mean shouldn't he be here by now?" As soon as my son said this, his papa Michael came swooping down.

"Harriel is that really you or should I call you Harry?" Michael asked our son Harriel curiously.

"I prefer Harriel if you don't mind and here is a copy of my memories in this pensieve. Also do you guys like my rings?" Our son Harriel asked us.

"So that's why Death said that he didn't have his ring anymore!" Dean gasped.,

"Yeah I'm sorry about that. So what are my domains and where are my blades?" I asked my parents.

"Well we hid the blades so no one but me, you, and Michael would know where they are and how to get there. The blade of Death is in the Upper region, while the blade of Life is in the lower region. They're in your manor in both places with one of our family crests on it." I whispered to my son after he put up a silencing ward.
