Initially Tony was at lost what to do. He barely could function himself when he was having panic attacks. When no one was around, he would just let things settle down naturally without actively counter his attacks. Suddenly he got an inspiration. It might be a terrible idea but it was the only one he got.

He started to sit on the spot where he stood.

"Sir, what are you doing?" Friday asked. At least she had the sense to be quiet.

"I'm going to take a nap here." He whispered. He lied down facing the front door so Stephen could only see his back. He thought it would be less threatening.

"Is it advisable with Doctor Strange's condition?"

"Do you think he is going to attack me?"

"Yes or possibly himself."

"Has he ever harmed anyone since he stayed here?"

"No."

"Then I trust him. As for harming himself, please monitor his movement and wake me up if he does something that may harm anyone."

"Sir, that spot hasn't been cleaned by your roombas."

Tony winced but remained still. "Are they taking days off? I'd like to cut their pay but they don't get any pay."

"I think they're malfunctioning again since you ignore them and focus on your new project."

"I guess they're too pampered. I'll change their programming when I wake up. Please remind me that when I wake up."

"OK, Sir. Can you at least get a pillow to make yourself comfortable?"

"If you have slept in a cave for months surrounded by terrorists or in the outer space without enough supplies, this floor is a luxury."

"I hope you make a good call, Sir. Have a nice nap."

"I hope so too. Thanks, Friday."

"You're welcome, Sir."

The floor was certainly far from luxury. However, Tony was too exhausted so a few minutes later he fell asleep.

The next moment he opened his eyes, he was disoriented. He heard a soft snore behind him and turned his head. He saw Stephen had fallen asleep around one foot behind him. He then remembered what happened.

Tony was covered with a warm blanket and he had a pillow under his head. He turned to observe the sleeping doctor and noticed he was using a blanket and a pillow with the same pictures of Spider-man. The doctor looked so young and innocent in his sleeping state. The billionaire shifted slightly to move move the bang that always fell on the doctor's face. Although he just spent time with the doctor for a few hours on the spaceship and Titan, he missed the doctor's goatee. He was tempted to draw one on his face and decided against it because that was the last thing Stephen need right now. He was not sure what the first thing the doctor needed but definitely not a fake goatee by someone who just used some electrical equipment.

He quietly crept out of the room and told Friday to notify him when the doctor woke up.

Five hours later, Friday told him that Stephen was awake.

Tony came in to the doctor's room to deliver a bowl of chicken noodle soup. The doctor just sat there reading some medical book Christine gave him. He looked up when Tony walked in and stayed quiet. At least he didn't cower in fear so Tony considered that as progress. He just put the food on the table and left.

He asked Friday to remind him about the next meal time so he could deliver it personally to Stephen. Pepper should be proud of him,

After two days, Tony was about to walked in to deliver lunch and he heard a laughter from Stephen's room that sounded like Peter's. He walked in and discovered that it was indeed Peter who was chatting amicably with the good doctor. He forgot that it was a Saturday.

"So Mr Doctor Strange, how do you reverse brain damage?"

Tony panicked. Had someone hurt Peter?

To his surprise, Stephen didn't look concerned and just answered calmly. "I think for the Flash's case, it's his personality. Nothing to do with brain damage so unless he wants to change, there is nothing you can do. At least nothing violent."

Tony sat next to Peter and started to try to look subtly at the kid from head to toes.

Apparently he failed at being subtle because he was Tony "I'm Iron Man" Stark.

Stephen looked unimpressed. "Peter is not hurt. I would know if he is because I'm a doctor."

Tony was impressed, that sounded like the old Stephen before this whole Tabula Rasa thing.

Stephen seemed surprised by his own statement. "Why did I say that?"

"Perhaps your old memory is coming back?"

The doctor stayed still for a few moments. "Nope, nothing returned about me being a doctor." Tony noticed he didn't mention about no memory coming back, just a specific memory. "Anyway, it's not about me …"He paused at that statement as if there was something there but after a few milliseconds, he shook his head. ".. it's about Peter. He told me how his friend, Flash.."

"He is not my friend," Peter sniffed indignantly.

"His classmate, Flash, tried to take Peter's lunch but Peter already knew beforehand so he put extra salt and chilli at everything including his drink. Flash tried to drink all liquid in the cafeteria afterward."

"I'm doing the food some favour. The food in the cafeteria is crime against good taste."

"Kid, you should just challenge your bully at the back alley and declared yourself King so he wouldn't dare to bully you anymore."

"Mr Stark, that's not my style."

Stephen also looked equally horrified. "Violence won't solve anything."

"I'll consider it as preemptive defense."

"Violence will lead to more violence."

"Not if we nip the violence in the bud."

"It will beget more violence when the victim retaliates."

"It will not."

"It will."

"Not."

"Will."

"Not."

"Will."

Peter's head snapped back and forth between Tony and Stephen and finally decided enough was enough. "I agree with Mr Doctor Strange that violence is not the solution but I'll not just lie down quietly to get bullied. So I guess I'm finding the middle ground between you two."

Stephen beamed at Peter. It was quite a sight because Tony hadn't seen the doctor beamed. "I'm sure you will find the best solution. I believe in you."

Not to be outdone, Tony added, "I believe in you too although I think my solution works better in the long term. We also need to talk about your lunch. I could ask Happy to deliver lunch for you every day."

Peter looked horrified. "I'll be the laughing stock of the whole school. Even other people will start to get the idea to tease me."

"Not if you are the King."

"Tony!"

"Mr Stark!"

Both Stephen and Peter wore the same horrified expression which was quite comical.

Seeing that Stephen could at least interact with others and not feeling afraid, Tony finally could feel some tension left his body . He knew recovery was not fast but at least he didn't need to tip toe around the doctor. He grinned. "Let's get some ice cream and play League of Legends."

Stephen groaned and Peter looked impressed. "Mr Stark, do you know how to play?"

"How hard can it be? Friday, please show me the rules."

Notes:

-Tony was not an expert so what he did might not be the best but Stephen inherently still trusted him so it worked out. If there was any inaccuracy, please kindly point it out. Stephen had not recovered and he would tell Tony about part of what happened that he remembered in the next chapter. It was meant to be this chapter but Peter decided to make an appearance.
-Sorry, I'm in a rush because I will be traveling overseas tomorrow and might not have the time to put up new chapters so this chapter is a bit rushed and short.
-Constructive feedback and comments are kindly appreciated.
-Have anyone seen the Far from Home trailer? It looks so normal like Infinity War has never happened so I wonder what happens in Endgame.
