It was manga based, set after Chapter 38. Jean was convalescing in some retired soldiers home, and they were keeping him "medicated" (AKA drunk) to keep him calm.
Roy comes to visit him and sees how Jean is in terrible shape and is determined to get him out of there.
So there is a bit of the fic where he is kinda nursing him back to health, then he eventually gets him out of there.
I want to say there may be some yaoi at the end, but I could be mistaken.
It was a one shot, but it was awesome. I can't find it anywhere.
