"You know I love you, don't you, Sammy?"
Sam stilled, fingers hovering over his laptop, startled by such an unexpected declaration from his no-chick-flicks big brother.
'Umm," he spluttered, unsure if Dean was playing some baiting game.
After a moment's hesitation, he turned.
Dean was dozing in the chair, eyes closed.
Sam allowed a half-smile to illuminate his features, Dean had been talking in his sleep, thank god, because Sam wouldn't have known how to answer, other than reciprocate the sentiment.
Secure and warm in his brother's love, he resumed his research, "I love you too" on his lips.
