Tony meeting multiple Steves

[marteshm1.livejournal.com]

I looking for a fic that i think was on AO3.
I Think the main story line is thatTony meeting multiple versions of Steve in some kind of separate detention only populated by Steve, they try to get him back to his universe while working agains another group of stoves that have another agenda.
They were all different and the scene I can remember was that Tony and a group of Steve had put
President!Steve together with a depressed one ( I think he may have died during WW2) and he had calmed President!Steve down with his depressed worldview.
Another scene( i think it's the very first) is Tony walking around in a fog like place where he meets a alternate!Steve for the first time.

I hope this is helpful=)

Thanks!
