Kidnapped!Tony, Secret Identity, Brainwashing?, Extremis

[gryvon]

 I'm going crazy trying to find a specific fic I remember reading. I'm really hoping it hasn't been deleted and I'm just failing at searching. I may be mixing it with a similar fic, but what I remember is:

• Tony's identity as Iron Man is a secret
• I think it's Steve/Tony but might be Bucky/Tony or Steve/Bucky/Tony
• During a battle Iron Man gets trapped under a collapsing building
• Tony's kidnapped by AIM or similar mad-scientist organization
• M.O.D.O.K. or someone else with mind control powers is trying to get Tony to do a thing for them, he refuses, they end up pushing the mind control hard enough to turn Tony into a vegetable
• Tony's injected with Extremis in an attempt to save his mind
• Steve breaks into Tony's cell just in time for Extremis to heal Tony's body and push the arc reactor out of his chest

Pretty sure the fic was pre-Civil War or Infinity War, possibly based on the comic universe instead of MCU.

Any help finding this fic (or fics if my brain is combining them) would be greatly appreciated.
