3rd Person's P.O.V.

Tony and Bruce were working on the tracking algorithm to track the cube. Well, Bruce was working on the tracking while Tony was messing around with Tsuna.

"Wow, how can you do all this?" Tsuna asked, starry eyed as she watched Bruce work.

"It's a little complicated to explain," Bruce discloses.

"What are you doing on-board anyway?" Tony inquires, munching on blueberries.

"I wanted to help. Fury won't let me though," Tsuna pouts.

"You shouldn't listen to that guy. I'm pretty sure that he has a stick shoved so far up his a-" Bruce cleared his throat loudly, muffling Tony's speech, and threw Tony a look. "What?"

"You have to remember that you're still a child. It's still too dangerous for an adult to go on any mission. Imagine how dangerous it would for you. You're not as skilled or as experienced as the other agents, you'll end up killing yourself and no one here wants that," Bruce explains, carefully.

Tsuna pouted as she could no fault in his logic but she still hated it. S.H.I.E.L.D. was everything to her. They were her family. Her mother, Uncle Clint, Uncle Phil, the other agents and even Fury! They were the real family she never had.

"Why are you so into helping anyway?" Tony asked.

"I owe them. My biological family abandoned me die when I was kid, they preferred my twin. I owe them for training me and to prove I am not useless," Tsuna reminisces, chuckling slightly as she rubs her scars while ensuring that the 2 men could not see them. "S.H.I.E.L.D. saved me and made me who I am today. I need to repay that debt. Beside, I tend to bring destruction wherever I go so why not use it to bug off Fury? If I don't then who will?" Tsuna jokes, hugging Natsu slightly tighter.

"I could do that," Tony shrugs, "I mean, that vein just pops right out once he sees me."

"You mean the one on his neck!" Tsuna exclaims, excitedly.

Tony wraps his arm around Tsuna's shoulder and uses his other arm to make a sweeping motion, "If both of us can piss Fury off by ourselves then imagine what we could do together. The destruction we can leave in our wake..."

"A match made in heaven. Let's do it, partner!" Tsuna high-fives Tony and simultaneously, everyone on-board on Helicarrier shivered at the unknowing oncoming doom that will soon sweep their future.

Bruce sighed in exasperation, "That's one match the world doesn't need."

"You know, what? You both should come by Stark Towers sometime. Top ten floors, all R&D. You'd guys will love it, it's candy land," Tony states, munching on a blueberry.

"Cool," Tsuna answers and Natsu growls in agreement.

"Thanks, but the last time I was in New York I kind of broke... Harlem," Bruce admits.

"Well, I promise a stress free environment. No tension. No surprises," suddenly, Tony pokes Banner with a miniature electrical prod.

"Wait!" Tsuna exclaims.

"OW!" Bruce stares at Tony in disbelief while Tony examines Bruce closely.

"Nothing?"

Steve walks in, irked at Tony's careless behaviour, "Hey! Are you nuts?"

"You really have got a lid on it, haven't you? What's your secret? Mellow jazz? Bongo drums? Huge bag of weed?"

"Is everything a joke to you?" Steve snapped.

"Funny things are," Tony responds

"Threatening the safety of everyone on this ship isn't funny. Tsuna was in here, what would you have done if she was seriously injured?" Steve alluded before realising what he was hinting at so he turned to Bruce, "no offence, Doctor."

"No, it's alright. I wouldn't have come aboard if I couldn't handle pointy things," Bruce reassures.

"And I can take care of myself!" Tsuna snaps.

"You're tiptoeing, big man. You need to strut."

"And you need to focus on the problem, Mr. Stark," Steve shoots back.

"You think I'm not? Why did Fury call us and why now? Why not before? What isn't he telling us? I can't do the equation unless I have all the variables," Tony explains. It was at this moment that Tsuna was starting to get nervous, if Tony delves deeper then S.H.I.E.L.D. could suffer but she knows he has a point.

"You think Fury's hiding something?" Steve questions.

"He's a spy. Captain, he's the spy. His secrets have secrets," Tony then points to Bruce, "it's bugging him too, isn't it?"

Bruce looked up, "uh... I just wanna finish my work here and..." Bruce said as he stumbled around with his words.

"Doctor?" Steve asked.

"'A warm light for all mankind,' Loki's jab at Fury about the cube" Bruce recalled.

"I heard it," Steve confirmed.

"Well, I think that was meant for you." Bruce pointed to Tony, "even if Agent Barton didn't Loki about the Tower, it was still all over the news."

"The Stark Tower? That big, ugly-" Tony throws Steve a look and Tsuna covered her mouth to muffle her laughter, "building in New York?"

"It's powered by an Arc Reactor, a self sustaining energy source. That building will run itself, for what, a year?" Bruce explained.

"That's just a prototype. I'm kind of the only name in clean energy right now." Tony informed the occupants in the room.

"So, why didn't S.H.I.E.L.D. bring him in on the Tesseract project. I mean, what are they doing in the energy business in the first place?" Bruce asked them.

"I should probably look into that once my decryption programmer finishes breaking into all of S.H.I.E.L.D.'s secure files." Tony admitted calmly.

"Wait, what?" Tsuna questioned, taken aback by the last part. That was extremely worrying.

"Jarvis has been running it since I hit the bridge. In a few hours we'll know every dirty secret S.H.I.E.L.D. has tried to hide," Tony informed them before holding a bag out to Steve, "blueberry?"

Steve ignored the bag and stressed, "Yet you're confused on why they didn't want you around?"

"An intelligence organisation that fears intelligence? Historically, not awesome." Tony throws back.

"I think Loki's trying to wind us up. This is a man who means to start a war, and if we don't stay focused, he'll succeed. We have orders, we should follow them." Steve advised.

"Following is not really my style," Tony argued.

"And you're all about style, aren't you?" Steve smiled, though it was fake.

"Of the people in this room, which one is; A. wearing a spangly outfit and B. not of use?" Tony snapped, the Captain's words obviously hitting a nerve.

"Steve, tell me none of this smells a little funky to you?" Bruce asked Steve before a fight broke out between him and Tony. Steve takes in the possibility but brushes it off, in order to follow the orders given.

"Just find the cube," he commanded and turns to walk out the lab.

"Um, I think I'm going to head back to the bridge," Tsuna mumbles, her body hunched over as she dragged her feet out the door way.

"Wait, Tsuna! I didn't mean anything bad!" Tony faltered.

"I know but..." Tsuna sighs before leaving. She knew Tony wasn't going to do anything cruel but he still threatened S.H.I.E.L.D. Her family. Maybe she was just overreacting but she thought it'd be best if she saw her mother.

"Oh god. I feel like s***," Tony complained, realising he went to far with his bickering with Steve.

"You should be," Bruce agrees, "you kinda threatened the organisation that saved Tsuna. She considers everyone here to be family. It's no wonder that she left after your threat."

"I just wanted to show that guy up," Tony explains, "I didn't mean to do that."

"You can apologise to her later, I'm sure she'll understand," Bruce assures.

"That star-spangled pretty boy thinks he's so righteous, eventually that's going to blow up in his face."

"And I'll read all about it," Bruce responds.

"Uh-huh. Or you'll be suiting up like the rest of us," Tony discloses.

"Ah, see. I don't get a suit of armour. I'm exposed, like a nerve. It's a nightmare," Bruce reveals.

"You know, I've got a cluster of shrapnel, trying every second to crawl its way into my heart," Tony points at the mini-arc reactor in his chest. "This stops it. This little circle of light. It's part of me now, not just armour. It's a... terrible privilege."

"But you can control it," Bruce explains.

"Because I learned how," Tony consoles.

"It's different," Banner tries to read the computer screen, but Tony slides the data aside with his finger so the two can see face-to-face.

"Hey, I've read all about your accident. That much gamma exposure should have killed you," Tony states.

"So you're saying that the Hulk... the other guy... saved my life? That's nice. It's a nice sentiment. Saved it for what?" Bruce challenged.

Tony responds without missing a beat, "I guess we'll find out."

"You might not like that."

"You just might."

Guh, I'm getting so lazy nowadays, work experience really took a toll on me.
