you are Remus and Tonks child. Teddy is your older brother his protective of you

You are sat by the black lake throwing stones across the water——— Teddy new you’d be there

He sits down next you and smiles at you softly. He wraps his arm around you and pulls you into a hug, wrapping you in his jacket

“You freezing….. I can feel yous shivering. Why you down here anyway?”
