Tony decided to trust Bruce because he felt he can be trusted and Bruce saved him from the cave. Tony didn't realize that he was subtly affected by the movie and since he believed its Bruce's life story and was a superhero in his world, Tony felt that they could work together and even wanted to check out his 'batwing' that he saw before. Tony didn't for a minute doubt the words of John as he can't guess the presence of "cheat" like John's system as that was unscientific.
The next day Tony went to meet Rhodes to say that if he would want to join in a project but Rhodes refused and asked him to take time and make his mind right.
After 2 nights at the home of Tony Stark, Pepper and Tony were one a side of the roof. Tony now had a new arc reactor in his chest as he changed with the help of Pepper. Tonight they were going to receive two guests.
The batwing descended at the roof which was covered in surroundings. Alfred and Bruce climbed out of the batwing.
"Welcome to my home. Hello Alfred." Tony said.
"Hello Master Stark. It's nice to you. It's nice to meet you too Miss Potts" Alfred replied. Tony noticed that Alfred was much young than he thought.
"Hello Mr. Alfred, Please step inside." pepper said
They directly went for the lab and started working on the suit for Tony. After few minutes of discussion Tony realized that Bruce was really knowledgeable and started making the proper changes in the design.
After a week of changes and adjustments to the actual Mark I drawings, the new suit was ready. Tony didn't have to go through any failed tests like in the actual version, like for example when he used more energy on thrusters and got slammed in the ceiling. Tony even added functions to avoid icing on his suit in high altitude after taking tips from Alfred.
Tony went for a test run which went perfectly and after the warning of Bruce he landed slowly in the roof as opposed to destroying the roof in the original version. Bruce also followed him in batwing to make sure everything went well in the test run.
"You should use gold titanium alloy to have a good power-to-weight ratio for the exoskeleton of the suit. It will help in pressurization and icing too" Bruce said.
"Yes that will help." Tony said as they discussed to make the suit better. Suddenly as they were discussing Tony from the corner of a eye saw the TV showing about a charity benefit of Tony Stark.
"I don't remember you being invited" Bruce commented as he watched the news. "Because I was not invited, Jarvis was I invited?" Tony asked.
"No sir, I have no such record." Jarvis said
"Then I guess you should get ready" Alfred said as he served a cup for them "I will bring out the suit. Miss Pepper is already at the event" Alfred said
"Thanks Alfred" Tony said while Bruce still looked at the schematics and thinking of how to improve the batsuit.
"Batsy you are coming too. Get ready. We need to go out and have some fun" Tony said.
"Yes Master Bruce you should also go and meet the people of this world. And maybe find someone interesting" Alfred added to Tony's comment.
"Fine" Bruce said.
"Jarvis paint the suit while we are out. Alfred don't you want to attend the event?" Tony asked.
"It's fine Master Stark, I will be at home going through your suit again. Jarvis will accompany me" Alfred said while smiling.
"Happy to be of service." Jarvis added
Tony didn't say anything and went to the event with Bruce. As soon as he reached the event, the reporters flocked to Tony. Tony even saw Obadiah and exchanged a greeting. Bruce and Tony then went to the bar to order drinks.
As they were taking a sip, Coulson appeared from behind and said
"Hello gentlemen."
"Oh I know you, you are from ... umm.. "
"SHIELD Mr. Stark and this must be Mister Bruce Wayne. Hello Mr. Bruce." Coulson said.
"You know Bruce? I thought only few people know of his existence." Tony was surprised.
"John is a consultant of their organization. I guess you came to know what happened in Afghanistan. I can give you a report after the event. Is that fine?" Bruce said
"Sure I will be here for that." Coulson said.
Later Tony saw pepper in a gorgeous dress and immediately asked for a dance. Bruce too danced with a woman. Tony went out with Pepper to the roof later and almost kissed but both backed out. When Tony came back to bar to get another drink for both of them, the girl reporter who slept with him before came and showed him pictures of Gulmira, the town where Yinsen was from.
"I didn't file any shipment." Tony refuted
"Well your company did." she said
"I am not my company." saying that he left and confronted Obadiah. Obadiah said he did all this protect him and the company including him being locked out. Tony stood there trembling in anger and immediately left.
