Charlie/Don, Alan has a heart attack

[kdorian.livejournal.com]

I would have sworn I posted this months ago, but I just looked through all the Charlie/Don, character death, and Alan tags and didn't see it.

All I can remember about this fic is that it is Charlie/Don, and towards the end of the fic Alan has a heart attack and either dies or has to move to a care facility, leaving Don in the position of moving back to the Craftsman to supposedly keep an eye on Charlie.
