The team is in a battle and during the course of the battle Tony's arc reactor is badly damaged. They need to get him back to the tower but for some reason can't take him out of the suit. Tony has Jarvis lock the suit so that he cannot move because he is having PTSD flashbacks and is worried about hurting someone and so that they can transport him. Back at the Tower Bruce has to operate (he maybe asks Natasha to help?), but Tony can't stand being awake during the surgery so he pleads with Bruce to sedate him. Afterwards, Pepper is very surprised that Tony trusted Bruce enough to actually ask for the sedation.
The story may be a Tony/Bruce one, but it could also be a Tony/Steve or Tony/Steve/Bruce. I can't remember anything more about the pairings or about the rest of the story. Could even be gen or het. Just that the suit had to be locked and that sent Tony even further into flashbacks.
Can someone help me find this? It has been driving me nuts for over a week now. Thanks in advance!
ED: Story has been found below. It is Jarvis, not Bruce that is involved. I've updated the tags to reflect the new information. Thanks to the poster who found it.
ED of ED: Mods, LJ isn't letting me me remove the Bruce Banner and Not Found tag. Help?
