What if everything had gone to plan when it came to Jack’s birth and there were no rifts popping up and no way for Sam and Dean to find Cas and Kelly. So Cas is just this new single dad in town doing his best to raise his son. Everyone thinks his wife died in childbirth, so he’s got the whole population of that small town fawning over him and his adorable baby boy.
People show up with casseroles and fruit baskets to supposedly help and welcome this busy dad and offer to babysit so he can get a wink of sleep. Cas is polite and sweet and he’s managing to make all the tired housewives swoon over him without even meaning to.
He goes grocery shopping with Jack strapped to his chest in one of those little backpack looking things and he takes him on daily walks around the park in his stroller. He does baby yoga and other activities with a mommy group that just couldn’t bare to say no. He takes Jack on play dates which mostly consists of moms flirting with him while the babies just have some tummy time. He’s completely oblivious to everyone falling for him, and he just thinks everyone is just really nice.
Somehow, Dean finds him one day. They hash things out, Dean holds Jack for approximately .05 seconds, and whatever tumultuous feelings he had evaporate in that instant. He keeps telling himself that things are fine and that Cas can handle the sweet little baby (who he had once believed was the antichrist) who grips his thumb and looks up at him with Cas’ big blue eyes. He tells himself he’ll be around for a couple days and then he’ll head back to the bunker.
But that turns into a week, then two weeks, then a month, and then he can’t imagine himself ever leaving that little house by the lake with the colorful nursery and living room full of books and bedroom that had become essentially his but felt a little too empty for his liking.
People around town were quickly scandalized at the appearance of this (handsome) gruff, rude looking man around their sweetheart Cas. Dean would get glares from some women in town and get hit on by others. He’d play it cool, but scurry off to find Cas (who was never far). Eventually, everyone would adjust to his presence and pay him no mind really.
Then, it would click for most people. Oh. These men are not just two guys looking after a baby. They’re together (the town is scandalized for a moment, but they get one another in line—Barbara it’s the 21st century, Edith you can’t call them homosexuals anymore, Theresa two men can raise a baby just fine, shut up Cathleen everyone knows your husband is nailing the poolboy).
When they see Cas and Dean holding hands while they walk Jack through the park or kiss at the drive-in or stand a little too close together in the checkout line at the grocery store a couple months in, they don’t know it’s a recent development, they just think they’ve finally gotten comfortable with the town.
They don’t know their complicated history. They don’t know that just a month or two before, Dean slept alone in the master bedroom in a too-empty bed. They don’t know that Cas would hold back three words whenever he’d catch Dean on the couch with Jack asleep on his chest. They don’t know that Dean would constantly catch himself staring at Cas, his heart beating erratically. They don’t know that Dean, after setting Jack down to sleep in his crib one night, tired himself out by watching movies with Cas into the early hours of the morning (unable and unwilling to give up the warm presence beside him on the couch for his far more comfortable and far lonelier bed upstairs). They don’t know that, forgetting himself, Dean eventually extricated himself from the comfortable confines of the couch, said goodnight, gave Cas a sweet kiss, and didn’t realize what he had done until he was already half way up the stairs.
They do, however, know that they’re in love.
