Disclaimer: I don't own Supernatural. That, however, doesn't stop me from raving and fangirling about it. Although, come to think of it, it doesn't stop me from a lot of things. Like my favorite pastimes, which include writing, singing and annoying my sister to homicidal proportions. Love you, sis!
Castiel peered over the crib. The baby inside smiled, cooing up at him. "Hello, Dean," Castiel said gravely. "I have returned from my visit to Heaven. I must warn you that Gabriel has learned about you and he wishes to meet you. If he gives you candy, do not accept. You are not yet old enough to consume the quantity of sugar he does."
Little Dean laughed, waving his arms at him. Castiel took that as a sign that he wanted to be picked up. He cradled him to his chest. "It has been four months since I had been sent to guard you. I am sure you will be pleased to know that I have had no trouble thus far." Dean gripped onto his coat lapel, giggling as Castiel swayed from side to side, a motion he learned from watching Mary. "You will be happy to know that your father will be home soon. Your mother is in the kitchen. She seems to be in a joyful mood. She is singing. I believe the song is called 'Hey, Jude'. I do not understand what the patron saint of hopeless causes has to do with it. Gabriel keeps telling me that I should brush up on modern culture," he reflected. "He seemed exasperated when I told him that I did not understand the term 'brush up on'." He frowned, looking down at Dean. "A brush is an implement used for grooming the hair, is it not?"
Dean just laughed.
Just then, Castiel heard Mary's footsteps as she walked to the nursery and hurriedly but carefully placed Dean back in the crib. It would not do for Mary Winchester to see her son floating in midair, seemingly cradled by some invisible, albeit angelic, being.
Mary walked into the room, moving over to stand by the crib. She smiled down at her child. "You're awake, are you? Just in time, too. John should be home right about-"
The door opened.
Mary smiled. "-now." She picked up her son. "Let's go greet your father after a hard day's work, shall we?" She turned and walked softly out of the room, Castiel following silently behind her.
"Welcome home," Mary greeted her husband.
John smiled at her. "Hey." He moved closer so that he could look down at Dean. "Evening, Dean. You been good for your mom?"
"Very," Mary assured him. "Dinner's almost ready. Why don't you go freshen up?"
John grinned crookedly. "I really need it, don't I?"
She gave him a smile back. "Yes. You do."
He heaved a sigh. "I guess I have no choice, then, if the wife demands it." He gave Dean a quick kiss on the forehead before going off to take a shower.
Mary fondly watched him go, then turned and padded back to the kitchen.
As always, Castiel watched over them, unseen. Except, of course, by his giggling little charge.
