Tony watched, half in appreciation and half in wonder, as Dr. Cho, Dr. Kim and the rest of the team at the lab turned machines and monitors on, hooked him into the blood purification system and performed pre-surgery checks – all very efficiently (and he liked that). For a moment his mind went back to the dark cave in Afghanistan where Dr. Ho Yinsen had performed a similar surgery to save his life, albeit with more ingenuity than precision medical equipment. The memory of Dr. Yinsen's death strengthened Tony's resolve to keep up his mission as Iron Man once he had recovered – Iron Man was a part of him he could not do away with even if he wanted to as it was his best bet to make up for all the time he had wasted in drunken haze. He turned and saw Amii outside the glass walls, her eyes closed, palms together as she mouthed a prayer, and he felt immensely thankful for having her in his life.
"We will be putting you under in a few seconds" Dr. Cho's voice brought him back from his reverie. He smiled at her "You come highly recommended, Dr. Cho. I guess I am in the right hands and though I prefer to be in control, this time I am ok to take a back seat. Would you mind if I had J.A.R.V.I.S observe?" he asked. "No, not at all" said Dr. Cho. Tony asked Dr. Kim to remove a portable projector from the pocket of his coat and activated J.A.R.V.I.S and tasked it with monitoring the procedure and providing Dr. Cho with assistance and information should she request it.
He felt a needle prick his arm as a nurse started another IV with sedatives. "You will be out for about 10 hours" said Dr. Cho as Tony's eyes became heavy as he floated away into unconsciousness.
Amii watched from the other side of the glass as Dr. Kim and her team got busy. She saw Tony talking to her and she received a ping on her smartwatch when J.A.R.V.I.S came online. She realized that Tony has tasked the AI with the job of monitoring the procedure. She watched as Dr. Kim's team went ahead with the surgery to remove the arc reactor and the splinters from Tony's chest. At the moment that the reactor came out, Tony went into cardiac arrest! The monitors started beeping loudly, red lights began to flash and Amii saw Tony's body heave as the doctors began to work frantically to bring the situation under control. Amii's felt her heart pounding in fear and she nearly fainted as she saw Tony flatline. She screamed "What's happening? Is Tony ok?" into the intercom. Dr. Kim's calm voice came back "Do not worry, Dr. Singh, we anticipated this eventuality and are well prepared to tackle it. I am going to darken the glass wall now and you won't be able to see into the OT for a while. This will help me and my team focus on Tony. It will take 15 hours or more for the surgery. I suggest that you grab some food and rest." And the glass went black.
Amii screamed in frustration and pounded at the glass wall for a few seconds before giving up and collapsing to the floor. She willed herself to calm down and took deep, deliberate breaths, getting her mind under control. The cool, rational part of her took over and she realized that Dr. Kim was right. The best team of doctors in the world was in that room which meant Tony was in good hands. She and Tony had discussed this eventuality and Tony had said that something like this would happen when the reactor came out and he had prepped Dr. Kim with the necessary information on how to deal with such a scenario. J.A.R.V.I.S was working with Dr. Kim and was providing the data around the reactor core, how it was linked with the casing in Tony's chest and how to remove it without killing him in the process.
Amii knew that she was not going to be of much use inside the OT and staying in the observation room was only going to make her more antsy. So she decided to step out for some air, she know she won't be able to eat or sleep till she was sure that Tony was ok.
