Im looking for this fic and im gonna kick myself when i find out what it is bc it seems obvious
SO all i remember is that Steve was kidnapped and they keep drugging him so it taints the blood sample and he talks to tony through a gap in the wall bc they're supposed to become friends for leverage and they do and then they escape together. I'm pretty sure everyone thinks tony is dead but i might be mixing fics there. Im also pretty sure it was on ao3 but once again not sure.
THANKS SO MUCH ILY
