First Lab Day (The Day After Thanksgiving)

Peter was practically beaming with excitement when he woke up the next morning. Normally, he and May would spend the day after Thanksgiving staying home possibly shopping online to get the good Black Friday deals, or he would spend the day with Ned. However, this time was different because he was going to spend the day with Tony to officially start his internship. Yes, he had spent time with Tony before recently in the last few months, but now was different. He was gong to spend time with the billionaire every week! One day or two or a weekend would be just him and Tony in the lab or in the living room watching movies. With that, he woke up that Friday morning at 9AM because Happy was going to pick him up at 10:30 to avoid traffic, and Peter was supposed to come home around 6:30PM with Tony so that they could have dinner with May, which Peter was completely okay with.

As soon as he finished his cereal that morning, Happy texted him saying that he was outside waiting for him, so he quickly texted the head of security back that he would meet him outside shortly. The teen cleaned his bowl, spoon, and glass placing them in the dishwasher and kissed May goodbye before rushing downstairs. He walked down the stairs all the way to the main floor and walked out the front door only to see a familiar black Audi parked in front of the building.

Peter smiled as he walked over to the Audi feeling his heart pounding with excitement. "Hey, Happy," he said as he got into the backseat of the car.

"Hey, kid," he said smiling at Peter in the rearview mirror, "I see you've come out of the food coma like I did."

Peter exhaled. "Even with the enhanced metabolism," he began, "I'm surprised I did."

Happy chuckled. "I'm sure your aunt will be doing a lot of shopping today, huh?" he said as he pulled the car into the street driving back toward the tower.

"Yeah, but we usually just stick to shopping online," Peter said. "Not a big fan of the Black Friday crowds."

"Well, the boss and Ms. Potts will definitely like you both even more hearing that," Happy replied. "They tend to rely on the Internet for this particular day. I know I do."

Peter couldn't help but chuckle. "Well, Mr. Stark said to me last night we should spend Thanksgiving together next year," he said leaning forward in his seat, "so maybe we can hunker down together for Black Friday, too."

"Really? He said that?" Happy asked sounding somewhat surprised.

"Yeah, I think it'd be really cool, don't you? To have a Friends-giving next year?"

"Yeah, kid, I do."

The ride to the tower was smooth for Happy and Peter as they left Queens and made their way into the streets of Manhattan. Happy pulled up in front of the building, and Peter could only marvel at it for a brief second before he grabbed his bag and began to exit the car.

"Thanks again, Happy," Peter said as he opened the door.

"No problem, kid," Happy replied. "Don't forget to show your ID badge to the front desk and take the elevator. Boss should be in the lab already."

"Got it, thanks," Peter replied as he quickly took his ID badge out of his pocket. With that, the teen got out of the door and ran inside the building, and once he was inside, he did what Happy instructed and showed his badge to the woman sitting at the front desk before getting on the elevator. "Hey, FRIDAY, Mr. Stark up in the lab?"

"Indeed, Peter," the AI replied. "I've been instructed by the boss to bring you to the lab as soon as you arrive unless stated otherwise."

Peter chuckled at how specific those instructions sounded. Tony was definitely very specific when it came to his AI. It was something he was noticing more and more with the billionaire, and it didn't bother him one bit. Not that it ever did, but Peter was just loving that he was getting this chance to get to know Tony more and to learn from him. As much as he hated to admit it, he was still just a kid, and like he told Tony, he wasn't ready for Avengers-level threats yet. He still had a lot to learn, and the fact that Tony was willing to be close to him and to work with him was an amazing feeling. The man believed in him and wanted him around as a mentee…as an intern, and he refused to let anything get in the way of that.

The elevator doors opened, and sure enough, there was Tony in the lab waiting for him. Peter smiled to himself and practically jumped off the elevator and ran into the lab as FRIDAY opened the door for him.

"Hey, Mr. Stark!" the teen said happily.

"Hey, kid!" Tony said looking up at his intern with a huge smile on his face. "How was the drive over?"

"It was great!" Peter replied as he placed his backpack next to him on the floor. "I'm so excited to work with you, Mr. Stark. You have no idea!"

Tony actually did. The whole morning, he was buzzing with excitement over the fact that he and Peter would be able to work together every week. "Well, I'm excited too, kid," the billionaire said with a smile. "It's great to have you here. However, there are going to be…some ground rules."

"Like what?" Peter asked suspiciously.

"Well, number 1, you're not to be in here alone, only when I'm in here," Tony began holding up a finger.

Peter nodded. He understood that Tony was a billionaire, and the technology he worked with wasn't something one could find in a dumpster. As much as he hated admitting it, after what happened with the Vulture incident, he understood. "Absolutely," Peter said quickly.

"Okay, number 2, no chemical or electric experimenting without giving me a heads-up," Tony continued. "I know you're a smart kid, but you're my responsibility here. Frankly, I don't plan on having your aunt coming after me if she learned that you decided to experiment on chemicals without me knowing."

"Fair enough," Peter replied. "Web-shooter formula included?"

Tony stopped to think for a minute as Peter did have a valid question. He had been making his web formula on his own for a while. However, if there were any mistakes made…in his lab…that wouldn't be good news, but he also didn't want Peter to think that he didn't trust him. So, he gave Peter a small smile. "How about you give me the heads up anyway? On a case-by-case basis? Like if you want to try something new with it?"

"Okay, I can do that," Peter said nodding. It made sense. This was Tony's lab, so he would need to keep the man in the loop.

Tony nodded. "Now, rule number 3," he continued, "no giving DUM-E any…ANY…tools of any kind. Last time I did that, I was really considering giving him away to a community college."

Peter chuckled. "Noted, Mr. Stark," he said.

"Don't chuckle, kid," Tony muttered. "This is serious business. Rule number 4, don't trust DUM-E with a fire extinguisher. Bad things will happen."

Peter widened his eyes slightly and looked at the small robot before turning back to Tony. "What bad things?" Peter asked.

"He gets donated to a community college," Tony said with a deadpan expression on his face.

The teenaged vigilante laughed and shook his head. "Okay, you got it, boss," he said. "Anything else?"

"Yep, rule number 5, no messing around with either suits without clearing it with me first," Tony replied.

"Got it."

"Rule number 6, wear protective gear when necessary," Tony continued, "goggles, protective clothing, the whole 9 yards. Are we clear?"

"Yes, sir, absolutely," Peter replied nodding.

"Good," Tony said nodding in approval, "follow those rules closely, and everything will go fine, kid."

"Well, of course, it will," Peter said smiling. "I'm working with you, aren't I?"

Tony couldn't help but widen his smile. "You trying to butter me up, kid?" Tony asked.

"It's the truth, Mr. Stark," Peter said shrugging. "I mean, you've saved my butt quite a few times now. I know I'm safe with you."

"Well…then…let's get to work," Tony said as the smile on his face widened. "I need my intern's input on these suit upgrade ideas I had."

"Oh yeah, I got some, too," Peter replied excitedly as he quickly dug into his bag pulling out a spiral notebook.

Lunch finally came, and Peter and Tony reluctantly pulled themselves away from the project and went up to the kitchen in the penthouse to make something to eat. Both superheroes treated themselves to some sandwiches made by Tony himself, and the two of them sat together at the counter. Peter couldn't help but notice how he wasn't freaking out that he was in Tony Stark's living quarters, not that he would. However, even when he came to stay for the weekend, he didn't freak out like Ned probably would. It all just felt so…comfortable…and normal…very normal.

"Is Ms. Potts working today?" Peter asked as he and Tony got up to clean up. He realized that they sat up in the penthouse for about an hour, and not once did he see Tony's fiancée.

"Yup, unfortunately," Tony said, "the company doesn't take long breaks, especially when dealing with other countries. Thankfully, it's only just a light day, so she should be back later before we head back to your apartment."

"Awesome," Peter said with a smile. "So…not to get too personal…"

"Tread carefully, kid," Tony said with a smirk. "Keep it PG-13, huh?"

"Oh, ew, ew, no!" Peter said laughing. "No, I was just going to ask if you two set a wedding date yet. I mean you two are engaged, but you haven't said much about that."

"Yeah, it's still a work-in-progress," Tony said as he placed the dishes and utensils in the dishwasher. "I think we're just going to take our time it, you know?"

"Really?" Peter asked. "I thought couples got married right away."

"Well, in a Disney movie…maybe," Tony retorted jokingly, "but some couples wait a while. I think with the crap with the Accords and the Rogues, Pepper wants to wait until things calm down."

Peter stopped and stared at his mentor at the mention of the Accords and even the Rogue Avengers…Steve Rogers, Sam Wilson, Wanda Maximoff, and Natasha Romanov. Scott Lang—Ant-Man—and Clint Barton—Hawkeye—were under house arrest, but not much had been said about the four Avengers who went on the run. The Winter Soldier disappeared as well.

"Has…has anything happened with all that?" Peter asked somewhat nervously.

Tony sighed and smiled sadly at the teen. "Not recently, bud," he said patting him on the back. He looked around and wrapped an arm around Peter. "Between you and me, I've been putting Ross on hold. I like to watch the light blink."

Peter scoffed and shook his head. "But…y-you would tell me if things get hairy with that, right?"

"Absolutely, bud," Tony said. "If I need you or want you to lay low with me, I'll come for you without hesitation—not that I did before, but you know what I mean."

Peter smiled and nodded remembering Tony's words to him after the ferry incident.

"I did listen, kid."

"Do you know that I was the only one who believed in you? Everyone else said I was crazy to recruit a 14-year-old kid."

"I wanted you to be better."

"Good to know, Mr. Stark," Peter said smiling even wider.

Tony nodded. "Now, what do you say we get back to the lab? There's plans for a new project I want to show you…for the Iron Man suit."

"A new project? What…kind of new project?" Peter asked eagerly as they walked into the elevator to get back into the lab.

"You'll see, kid," Tony said as the elevator doors closed and moved back down to the lab. As soon as it stopped and the doors opened, the billionaire led the teenager over to his personal work desk tucked away in the corner of the lab. "FRIDAY, you ready for a little show-and-tell for the kid?"

"Of course, boss," FRIDAY replied.

"Let's bring up…" he looked at Peter with a smile, "Project Nanotech."

"Bringing up Project: Nanotech," FRIDAY replied. As soon as the AI responded, holographic screens appeared in front of Tony and Peter.

Peter's jaw dropped at the sight. There were screens of nothing but information on nanotechnology and the Iron Man suit. Finally, his eyes rested on a particular slide that had a triangular shape and a small glow in the middle. "T-That…Mr. Stark, that's…" he began to say, "that looks like—"

"An arc reactor?" Tony said with a smile.

"Yeah, but…I," Peter began looking at his mentor, "I thought you…" despite his shock, he wanted to tread carefully, "you got rid of the arc reactor, didn't you?"

"I did," Tony answered, "but this…this is something slightly different. I've been researching nanotechnology to put in the Iron Man suit. This arc reactor is to act as a…homing station for the nanotech. It will allow for much less time putting the suit on, and it's easier to carry around."

"So all you would need to do is just press a few buttons, and…BOOM…you got the suit on?"

"Exactly, and that's not even the best part. I hope to eventually install it in…the Iron Spider suit I showed you at the compound."

"Really?! Are you serious?!" Peter asked with glee and excitement.

"Very serious," Tony said nodding "So…what do you say, Peter? Want to help with Project Nanotech?"

Peter stared at him again. "Y-You're really asking me?"

"No, I'm asking the Man in the Moon right behind you. Of course, I'm asking you. You're my intern, and I think this could be a great project for us to work on together. So, what do you say?"

"I say…absolutely! Yes! Can we start now?"

Tony laughed as he put an arm around Peter's shoulders. "I thought you'd never ask, kid."

Author's Note: Annnnnnnd that's all for now, boys and girls! I really hope you all enjoyed it! Up next is a sort of hurt/comfort oneshot.
