Rhodey tony friendship or pairing fic? Because I love Rhodey (both versions of him, though I think I may love the second actor playing him more).
I am sad there is no character tag for him.
Any fic is fine barring crack.
Hi! I'm going crazy looking for a fic I read once and can't find now. Tony and Bruce were working on a machine that would shrink people, intending to use it on Fury as a joke. Coulson walks in the lab, and Tony tests it on him, and it de-ages him instead of shrinking him. Coulson ends up physically reliving his childhood, acquiring the same injuries he got as a kid, and also when he got stabbed. Loki turns up at some point and is forced to babysit and little Coulson liked him a lot, and I think Maria Hill was mentioned to be the cellist. Also, I think the overload of memories caused a brain tumor?
