Working my way through the season 9 boxed set, I've just finished the episode where Sam casts out Gadreel and then has the confrontation with Dean with Castiel having to watch as their relationship breaks down and Dean walks away, leaving his family standing in the rain.

I'm craving follow up fics to this. Cas told Sam he'd have to heal him in stages, suggesting he'd be at the bunker for some time. I've love to read fics where it's just the two of them, and Cas is left pretty much responsible for Sam's physical, mental and emotional wellbeing and takes really good care of him.

And maybe Sam cares for him in return, because Cas is still on rocky ground himself after everything that's happened to him.

I just think it'd be interesting to see how their relationship pans out because before it's always been Dean and Cas, or Dean and Sam and Cas, but now it's just them - and for all they know, Dean is never coming back.

Gen or slash, both are welcome.

Thanks in advance!
