Ok wow I'm such a dumbass. Reflexes was actually the first fic I skimmed through because I had thought it was the fic with the scene in it, but I did this rookie mistake and searched for just the word "Rhodey" instead of "Rhodes" and with no results, my brows went all scrunched up and I hit the internet trying vainly to find a fic I apparently already found.

Whew. Thank you so much for sparing me another few hours of going around in circles.
