Werewolves have a weird way of claiming things.

"Aye wha 'appened to yu?"

"Nothing" Sirius replied looking throughly disheveled.

Insted of simply putting a word claim to something, like mine or don't touch, they feel the need to be more savage.

"Donna look like no'tin" One of his house mates said following him to a spot in front of the fire.

They can't excatly bite you. That would be harmful. They could go crazy and end up killing you or you can end up with the same problem every month as they have.

"Really it isn't anything." He sat down the younger boy sitting beside him.

No they need to claim you fully. Inside and Out.

"Yu looka li'ke yu been hit buy a curse or somethin' more muggl' like a truc'"

They need to make you smell of them and them alone. They need to tear you apart and piece you back together.

"Nope no curses or Trucks."

Need to make your heart ache for them to hold you, your mind yearn for their voice and you body crave their form.

"So wha' makes yu looka so beat'n?"

They need to love you and hurt you at the same time. Making your entire being confused. They need to take you in their arms and love you until you beg for more. They need to clean you soul and rewrite it as their own. Need to erase all the other lovers you ever had. And make you whole exsistence about them.

Whats happened to me? What makes me look so beaten that this poor unsuspecting boy would think I was harmed?

A werewolf so in love he needed to claim. Needed to clean the slate and make me beg to be taken over and over until all I saw were stars. A wolf I love more then life itself who is the only one I walk for now. The only wolf who could make me change for him. A One Remus J. Lupin.

Sirius looked into the fire, flames dancing in his dark eyes. "Love" he answered simply as if it were easiest solved mystery in the world. And right then for him, it was.
