Sam sits in the middle of the room, giggling as the puppy nips at his fingers. He grabs the little dog around the body and holds it up in the air, laughing as it wriggles and licks his hands.
A car alarm goes off outside. The pup erupts into ferocious barking, struggling to get down. Sam cuddles it until it calms.
The door opens. Dean comes in, stops dead. "Oh, Sammy."
John is right behind him. His mouth tightens when he sees the dog. "Deal with this," he growls at Dean.
Sam ducks his head and tries not to cry.
