There's only one fic this time, and so (hopefully) the request won't be too long...
In any case, I remember quite a bit about the fic. For one thing, it isn't quite Post-Civil War - it actually begins in the bunker
I know that it was on Ao3, and I'm pretty sure it was multi-chaptered.
Please help me find this fic! I've been searching for it for a while, but no matter what I do, I just can't seem to find it!
