avengers and supernatural

this story is a little different. My name is Rose Madison. I am half Demon, half human.

I met Dean Cas and Sam while on a hunt. I went through a lot with the Winchester and the angel. one day, while we were trying to defeat Lucifer, I vanished literally like just disappeared.... but what we didn't know was that there was a lot going in this world with some guy named Thanos and the Avengers.

Nick fury finds me in a field. What will happen? Will they find out who I am and how they will react to what I am. Will they think I'm a freak aswell or will a certain soldier fall for me. Will I fall for him.

I don't own the characters from Marvel or supernatural
