"You’re cute," Dean repeats, completely casual, and Cas rolls his eyes.
"Yes, I heard you," he sighs, "But why?"
"I don’t know," Dean shrugs, but doesn’t look away from the violent clips of sharks on the TV, "It’s just—You’re literally God only knows how old, and you’re sitting there in a pair of fleece pajama pants and reading glasses that are too big for your face and you’re reading that Harry Potter book for the third time and still smiling like a five year old every time you turn the page," Dean shrugs again; smiling as he turns the volume up on the TV, "I don’t know. You’re just cute."
