I'm trying to put together a list of my favorite post-apocalypse fics and there are afew I remember reading that I can't find

-Dean and Jo set in the 2014verse where Jo is there is 2014 when Dean visits and he doesn't understand futre!Dean's cold attitude toward her. I think it had something to do with losing a baby or child. FOUND!

-I think I remember two with slightly twisty endings where either Jo kills Sam or Dean to try to stop things or Sam or Dean kill Jo. In one I think she ends up going to a beach and Sam is there to kill her. In another she finds one of them (I think Dean) and they live together for a while and maybe Jo kills the boy at the end. Wow, I remember a lot less of that one than I thought. FOUND

- I would be up for any more recs that have Jo and the boys after or during the end times. The more heartwrenching the better.

thanks!
