Characters are Dean Winchester, Castiel (background) and Claire Novak from Supernatural. Claire is depicted here in her mid-20s. She is 20 years old in season 12. This image is based off a private roleplay that takes place five years after season 15 end, sans the original ending. About Cas' outfit - he is dressed this way for two reasons. One, this is set five years into the future; two, Destiel/DeanCas is real, and before they had to deal with their wayward 'daughter', they had some ... play time.
