This is adorable and made me smile. Also, I love this: All of which Dean solved by squashing his little brother’s face to the floor with one big paw and calmly washing away the blood with his rough, pink tongue. When Sam squirmed and batted weakly at Dean’s head, Dean just squashed him harder and continued his work. It's a cute image, kitten!Dean grooming kitten!Sam, but it's also lovely that Dean's accepting Sam here and helping out and doing his best to make it all okay.
