A/N This is Bruce's first day at STARK Tower. Probably two weeks before Pepper and Tony called off the engagement. There will be more Avengers soon! Especially Hawkeye. He's just too cool to leave out. So expect lots of Bruce/Clint friendship! I own nothing. Even though I pray to every god imaginable every night that I did... I just don't.

Bruce gaped at the lab laid before his eyes. He tried so hard to not visibly geek out over everything. Trying to stay invisible meant that he usually had to make do with some iffy tools to help people. This, this was so much different. Everything was clean and neat. Bruce laughed to himself when he realised it wouldn't be like that too much longer when he and Tony started working. Everything was so amazing! He just couldn't wait to start! Feeling Tony's eyes on him, Banner was transported back to reality. Don't look too eager, Banner. Play it cool. Deep breaths, Bruce. Deep breaths.

"It's neat."

Tony's shoulders slumped slightly. "Yeah. Thought it'd be cooler now that it's all redone and tricked out, but I guess not." He spun a globe around gloomily. "Same old boring stuff."

"I can't wait to get started, Tony. You have some really amazing stuff."

Bruce kept his voice level and tried not to squeal as he poked around shyly. He glanced over at Tony who was pouting in his chair. Bruce wondered why. It couldn't be anything he said, could it? Tony knew that nothing could beat what he had. So why would he be so down about what some monster had said? He wouldn't care, so it had to be something else. Bruce wondered what he was missing out on.

Tony jumped to his feet and clapped his hands together. "Well this is all boring stuff, so let's see where our rooms are. I kinda let JARVIS take over the main building plans and send them to the builders. But Fury wanted this to become a temporary HQ for the Avengers, so I'll personalize the rooms for everybody. It'll be great!"

"B-but.. the labs.."

"No need to pretend you're super interested Brucey. I get it. You've seen it before on SHIELD's ship. I knew they've been keeping stuff hidden from me." Tony clapped him on his back and shrugged.

Bruce didn't know what to say. It was all so amazing. How could Tony think otherwise? Anger flared inside him momentarily. Maybe he was just rubbing it in. Maybe he knew that Bruce would be so blown away and he decided that he would just brush it off and act as if it was nothing. Act all snooty and rude. But it was all probably just a joke to get Bruce to Hulk out. So he calmed down. He wouldn't let Tony get the better of him.

"Fine. Where's my room, JARVIS? I need to rest." Bruce testily asked the AI. He really didn't want to deal with Tony right now.

A disembodied british voice spoke. "On the 115th floor. Take the elevator, go down the hall on your left and your room is in the first door on your right. Stark?"

Tony rolled his eyes. "What?"

"Have fun finding your room."

Bruce laughed bitterly as he was getting in the elevator. Bastard deserved it.

"Jerk. What? Weren't even going to hold the door open for me?" Tony stepped into the elevator, glaring daggers into Bruce's skull.

Christ! What is his problem? Bruce looked Tony in the eye and gave him his best glare.

"I only hold the doors for ladies, Tony. And by the looks of it you are very much a man. But if you have some big secret to tell me, one along the lines of 'I'm actually a woman', please tell me. It would explain your bitchy attitude right now."

Tony scoffed. "I have a bitchy attitude? Me? You're the one with a bitchy attitude!"

"I do not! I can't beleive you would say that. No, actually I do. Because Tony fucking Stark never does anything wrong!"

"You know what, Bruce?"

Bruce raised a sarcastic, questioning eyebrow.

"Fuck. You."

"You are so damn childish, Tony!"

The elevator dinged open and they both turned their heads at the same time to see Pepper standing warily outside the door.

"I'm going to take the next one. JARVIS?"

"I know, Ms. Potts." The elevator shut despite the men's protests. They could barely hear Pepper yelling at them to sort it out. Bruce looked up to see they were on the 91st floor. Like they could sort it out in that little time. Which they so weren't. Nope not even going to try. Only a few more sec-

Suddenly the elevator stopped and the lights went out. Oh, no. They couldn't be... Pepper wouldn't.

"She stopped the elevator. That horrid b-"

"Don't make her anymore angry!" Bruce punched Tony on the arm.

"Ouch!" He rubbed his arm and quickly stopped. "... Is what I would say if that actually hurt."

Bruce rolled his eyes and stepped away from Tony. They had been really close when they were yelling. Kissing distance close. Not that Bruce would ever kiss Tony or think about it...

"Why are you so grumpy, Tony?"

Tony gave him a look that seemed to say 'you're-kidding-right?'

"What?" Bruce was really at a loss and was getting frustrated. Not enough for the other guy to be a problem, but Tony was still annoying.

Tony pointed an accusing finger at Bruce. "You don't even like my stuff! You just blow it off like you've seen better! You just act all prissy and rude and it really PISSES ME OFF!"

The Man of Iron huffed and sat down in the corner furthest away from Bruce, pulling his knees to his chest and wrapped his arms around them. He looked like a child who was sent to sit in the Time Out Corner.

Bruce visibly calmed down and gave Tony a confused look. "Tony. You have the best equipment and technology in the world. You've known that since you were a kid. What does my opinion matter?"

Tony's face turned red and he mumbled something into his knees.

Bruce slid down on the floor next to him. "What?"

"We're Science Bros. You're the smartest person I've met. I don't have to explain anything to you or wait for you to understand. Your opinion does matter to me, Banner." Tony mumbled quietly.

Bruce nodded shyly. He had never been important in that way before. He never actually mattered. It was so new and... nice.

Both men jumped slightly when the doors opened to reveal a smiling Pepper Potts. "You two good?"

The superhereos before her shared a look and Bruce looked to Pepper. "If you don't mind Ms. Potts, Tony and I are going back to the labs."

Pepper nodded, trying to keep a straight face. As the doors were closing she saw Tony slightly jumping with a big grin on his face and Bruce giggling.

The doors closed; Pepper laughed out loud. Those two were made for each other. It was just too sweet. The more she thought about it throughout the day, the more she realized she didn't want to get in the way of what they had. She would have to have a talk with Tony once she got back from her business trip in Japan.
