just
the idea of sam and dean bundling cas back up and taking him to the bunker and tucking him into bed and he just sleeps and sleeps and sleeps for days
they take turns looking in on him and pressing their hands to his forehead to see if he’s sick
til one morning sam’s up early, really early, and when he wanders into the kitchen it smells like coffee and cas is up already in sweats and a big t-shirt just sitting at the table drinking his coffee black, so hot it’s scalding, and he says “coffee’s on” so sam silently gets a cup and sits down with him
and finally sam says “you can be human, cas, you’ve been doing it for years but you just didn’t know it”
cas smiles a little into his mug and they sit there drinking their coffee together
and they both know it’s going to be okay
