Dean has always thought, secretly, that part of -- or most of -- the reasons why they end up finding (and eventually getting) a house in California, is because of the variety of birds here, just because how much Cas loves these little winged creatures. Though Cas always says it's because of how close it is to the shores and therefore beaches, which is Dean's favorite.
"The perfect amount of green and blue," Sam has commented with a grin, when they give him a tour. Which, of course, means the color of woods and sea, Dean has thought.
And that has been a long time ago. Ten years, to be precise.
Dean has get used to waking up to the sound of waves and birds' chirping outside their window; he has get used to the warmth of the body that belongs to his husband when he turns in the bed, semi-consciously and half-awake, and wraps his arms around his waist and shoulder, and he knows soft kisses would land on his forehead and hair soon enough, just after a beat or two.
Birds are chirping especially loudly today, though.
He senses the rustling hand between his hair pauses in the middle of the move.
Dean opens his lazy eyes, seeing Cas distracted, tilting his head slightly toward the window's direction.
"What's wrong, Cas?" Dean shakes his head, trying to get rid of the early morning sleepiness, cupping a hand on Cas's cheek.
Cas frowns a little, focusing on the source of the sound. "It doesn't sound right," he answers, shifting in a way that looks as if he tries to pull away but restrains himself from pulling away at the same time.
"The bird." Cas nods. His hair brushes Dean's nose. "It's a terrified baby. Listen."
Dean listens. Indeed, now that he pays attention, there's a small cooing sound that's different from the usual birds' chirping. And if he gives it more imagination, he'd agree that it's a "terrified" sound.
Cas already starts getting off the bed as he listens. "He must somehow get lost," he says, looking thoughtful.
Or abandoned. Dean thinks, but he chooses not to say it. It's never a happy topic to wind up to.
"Come on, we need to help him." Cas wraps an oversized shirt around himself -- which, of course, is one that he's stolen from Dean's closet.
Dean follows him to the yard.
The baby seagull is struggling between the strawberry vines and roses that Cas planted just several months ago, cooing helplessly. Its eyes barely open. It's all round and fluffy with grey fur, no bigger than a fist's size.
"It's a fledgling." Dean looks at the tiny little thing.
"Hatchling, actually." Cas corrects him, reaching out his hands to pick up the miserable little thing, covering it with his fingers. "I don't think he's more than three days old, not even a nestling yet. A fledgling would be about two weeks old."
"Nerd," Dean chuckles lightly, following Cas back inside. "What do we do now?"
Cas heads straight to the kitchen. "Feed him. He's starving already, and I don't see his parent anywhere. I'm afraid we'll have to be his foster mom for a little while until he can feed himself."
The little thing opens its beak so wide right then and pecks Cas's fingers.
"Yep, definitely hungry now." Dean opens the cupboard, searching. "What does it -- he -- eat? Not popcorn, I assume?"
"Regurgitated food, ideally. Berries, worms, shrimps, most ideally," Cas answers quickly.
"I'm not gonna mouth-feed the baby!" Dean protests, staring at him.
Cas chuckles. "That's a joke. Anything soft and small should do; they're usually not picky. Common cat food or dog food, as I understand, should also work."
Dean grabs the bag of dog food sitting in the corner of the cabinet. "Don't let Miracle know," he says, pouring a small portion into a bowl.
"I'm sure Miracle would be willing to share," Cas answers, instructing him to soak the dry dog food with water and starting to hand-feed the baby bird.
The hatchling swallows the food so quickly that Dean even starts to worry if it -- he -- might get choked. But he trusts Cas must know those little creatures well enough -- in fact, now that he shifts his attention from the baby bird to his angel husband, he starts noticing how attentive Cas is, and the gentleness in his eyes that is usually reserved for Dean.
Dean laughs at himself for getting jealous of a baby bird.
The view is actually surprisingly comforting just to see Cas pick up a tiny piece of wet food to the bird's mouth and the bird would just swallow it altogether and coo for the next bite. It's almost like a ritual. There must be something biologically impacting in babies that makes any other species feel uncontrollably maternal and nurturing. Dean doesn't realize he's staring and can't stop his mind wandering afar.
"It reminds me so much of taking care of fledglings back then," Cas starts suddenly, without looking up, his tone nostalgic.
Dean gets confused for a moment. "You've taken care of other birds before?" he asks.
"Not birds, angels." Cas glances up, giving him a short but warm smile. "You might say angels are incredibly similar to birds, in a way, especially when they're young."
Dean blinks. He's not expecting that, not really. Of course he knows about wings and all, but fledglings, really? His brain starts supplying imaginations of fluffy little furry balls that are like humans with tiny little wings, crowded in a nest, waiting to be fed. Which is just a little too surreal to think about. Dean shakes his head briefly. "You gotta elaborate."
"Some of the angels are fully grown the moment they're created -- Michael, Lucifer, Raphael, and Gabriel, which makes them incredibly strong and complete," Cas starts slowly, pausing on the feeding task now. The little thing looks more round than a moment ago, its neck hidden by the pluffed crop plumage. "Others are born, instead of being directly created; therefore, they'll have to be taken care of, nurtured, fed, and brought up, until they're grown."
"And... you?" Dean can't help but ask.
"Gabriel is the one who brought me up," Cas answers, looking down at the floor, still holding the hatchling between his hands, but his thoughts are obviously flowing away from the current time. "And I personally have brought up quite a few, Sammandriel is one of them, Balthazar too." His voice lowers quickly as the names come out, and dies down in a dry sound.
Dean finds it suddenly too much information to even reply.
"And I killed both of them, and so many others." Cas struggles to finish, but he pushes those horrible words out. His fingers stroke the little bird's back absent-mindedly. The hatchling starts cooing again.
Dean rushes to hold his shoulders, stroking the back of his neck reflexively to comfort. "It's not your fault, Cas. It's all past now."
Cas looks up at him with a pale smile. "I know."
The bird starts pecking his fingers again, pulling his attention back. Cas goes back to the second round of the feeding. With more attentiveness, with even gentler touch. For a while, Dean thinks he might be imagining that this is exactly something happened that millions of years ago and the baby bird is another angel. He wonders how many other stories he doesn't know about angels, and more specifically, about Cas before they know each other. It seems even after ten years of story-sharing, he's still able to find out new things -- and still big things -- about his fascinating partner.
Cas pauses the feeding again when the bird seems to be full, and resumes the move after about another twenty minutes.
Dean clears his throat, pulling his attention back. He offers a shift after the next round of feeding. Cas carefully hands the bird into his palm, and instructs him on what to do.
The little thing pecks his finger impatiently when he offers the food too slowly.
"How frequent are we supposed to feed?" Dean can't help asking, feeling his arms start to get sore just after about three feeds.
"Twenty minutes, give or take, from sunrise to sunset. We can change to about an hour when he turns into a fledgling." Cas glances at their kitchen clock. They've been here about all morning now.
Dean lets out a quiet groan, feeling the muscle on his back start protesting for staying in the same posture for too long -- he's not young anymore, after all. "Jeez, it's like breastfeeding," he moans.
Cas chuckles gently, taking over the bird again and ordering him to have some stretch, which Dean totally needs. "I'm sure breastfeeding a human baby would be a lot more exhausting."
Dean hums noncommittally, stretching his arms and pacing slowly in the kitchen. "But then, the way I heard it, and I'm sure that's what Sam would say if he's here, 'They'll go to college before you know it'. Babies tend to grow fast, you know."
Which turns out to be the exact truth, especially in the case of a baby bird.
After exactly six weeks, the fledgling -- now that his little fluffy grey plumage has already turned into white real feathers -- flaps his wings and lifts himself off the ground. And on the first day of the eighth week, he flies higher than the edge of their yard and shoots toward the sea's direction in a cheerful yell.
Dean stands at the edge of the yard, watching it turn into a little white dot against the blue sky, turning unusually quiet.
Cas stands next to him, just as quiet, watching in the same direction. He reaches to hold Dean's hand, and gets grasped immediately.
"They grow so fast," Dean hears himself sighing. "Now I get why it's called Empty Nest Syndrome."
Cas tilts his head and watches his side profile for a long minute, thoughtful.
Dean turns and meets his eyes. "What?"
"I've been thinking," Cas starts slowly, "would you be interested in raising a real human baby? Adopted, of course. I know you'd be a really good father, Dean -- not just for fledglings."
Dean is choked for words for many seconds. When he can speak again, his words stutter, "Us? Raising a kid together?"
Dean swallows, wetting his dry lips with his tongue, holding Cas's hands tighter unconsciously. "Let me think about that, alright? It's kinda big."
"Of course," Cas answers with a gentle smile. "Of course."
