3rd Person's P.O.V. 

Fury sits up, clutching his ribs, he quickly puts on his earpiece and calls, "Hill?!"

The Bridge

Pandemonium envelops the whole bridge, alarms were blaring, agents were scrambling around to get into position. Agent Hill, staying calm, was issuing commands, "Turn up that engine! Number 3 engine is down! Can we get a run in. Talk to me."

The galaga player points to monitor, "Turbine's loose. Mostly intact, but it's impossible to get out there and make repairs while we're in the air."

'We lose one more engine, we won't be. Somebody's got to get inside and patch that engine," Hill warns.

Bruce's Lab

"Stark! You copy that?!" Fury demands.

"I'm on it!" Tony replies.

"Coulson! Initiate official lock down in the detention section then get to the armoury! Move out!" Fury orders before jerk in Tsuna, who was still peering down the hole her mother fell through, back onto her feet. "Come on Cielo!" Fury drags Tsuna back to the briefing room where all the panicking agents were trying to get everything under control. 

Near Engine 3

Captain America makes it to the 3rd engine where a large part of the ship has been blown apart. He sees multiple S.H.I.E.L.D. techs in oxygen masks trying to put the flames out with fire extinguishers but sparks are still flying.

"Stark, I'm here!" Cap calls out.

"Good. See what we got," Tony flies in his suit and gets close to the damaged engine, using his view screen he assesses the damage done onto the engine and its layout. "I gotta get this super conducting cooling system back online before I can access the rotors and work on dislodging the debris."

Iron Man starts pulling at the tuck rotors before turning to Captain America, "I need you to get to that engine control panel and tell me which relays are in overload position." Iron Man then flies into giant cooling conductors. Captain America leaps over to the other side of the broken railing and opens up the control panel, he stares at it in bewilderment.

"What's it look like in there?" Iron Man asked.

"It seems to run on some form of electricity," Cap sighs in exasperation and annoyance. Technology. Why you gotta be so complicated?

"Well, you're not wrong," Iron Man points out. He continues to blast broken debris off the turbine engine. 

"The relays are intact. What's our next move?" Captain America reports.

"Even if I clear the rotors, this thing won't re-engage without a jump. I'm gonna have to get in there and push," Iron Man admits.

"Well if that thing gets up to speed, you'll get shredded!" Captain America warns, he really didn't like that idea, though he couldn't deny it sounded good for a moment.

"Then stay in the control unit and reverse polarity long enough to disengage mag-" Iron Man tries to explain before being cut off by Steve.

"Speak English!" Cap demands, fed up with all the incomprehensible science talk.

Tony sighed before simplifying his explanation, "See that red lever? It'll slow the rotors down long enough for me to get out. Stand by it, wait for my word," Iron Man orders. Captain America looks over at the other side where he was and sees the red lever so jumps towards it.

The Bridge

Fury and Agent Hill look over their monitors.

"We need a full evac on the lower hangar bay," Fury orders and Tsuna and Hill nod, they were about to leave when a sliding grenade rolls into the room.

"Grenade!" Tsuna exclaimed, shoving Hill out of the way and sent them both tumbling over the railings when it went off.

Fury fires a single shot at the open entrance before moving over behind the side of the entrance. A handful of Clint's men enter and Fury steps out with his gun drawn. Fury was able to beat down most of them but one manages to escape his sight. The man was about to shoot Fury through the head when he, himself, is shot twice. Both Hill and Tsuna were holding a smoking gun.

"Thanks Tsuna," Hill says.

"You're welcome, Aunt Maria," Tsuna replied. The two back behind cover as a gunfight opens up.

"We have the Hulk and Thor on Research Level 4. Level 2 and 3 are dark!" Sitwell warns over the intercom.

"What do we do?!" Tsuna exclaimed, reloading her gun.

"Sir, the Hulk will tear this place apart!" Hill shouts over all the chaotic noise.

"Get his attention."

Hill speaks into her earpiece and issues the next command, "Escort 606, proceed to 270 main shuttle! Don't get too close," she warns.

"Copy," the pilot responds. Unfortunately, his attempts were futile as Hulk tore his jet apart and he was forced to eject.

The gunfight continues but it was obvious that the enemy wouldn't get passed which confused Fury.

"They are not getting through here, so what the hell..." Fury muttered when suddenly, Clint lets loose an arrow down to the bridge which explodes, sending agents flying away from the control desks. Clint then releases a multi-tipped arrow towards Fury, but it instead hits his command desk, right above a USB outlet. Fury fires at Clint who is already gone. The arrow then activates itself and inserts itself into the outlets, hacking every single monitor and main frame which causes engine 1 to shut off. The Helicarrier dangerously begins to tilt to one side.

"Sir, we've lost all power in Engine 1," Sitwell states.

"It's Barton. He took out our systems. He's headed for the detention level. Does anybody copy?" Fury asked into his earpiece.

Lower Equipment Room

Still shaken by the haunting experience from the Hulk, Natasha sat rocking back and forth. Summoning all her coolness, she touches her earpiece, "This is Agent Romanoff. I copy."

The Bridge

Tsuna look at around, breathing heavily, her bangs stuck to her forehead due to sweat. The ship was tilting, they were going to crash. Not if she had anything to do about it. Tsuna leaps over the control desk.

"Cielo! Where are you going?!" Fury demands.

"I'm gonna save your butts!" Tsuna yelled without looking back. She dashed to engine 3, fighting against all enemies who got in her way and having Natsu petrify their weapons and bullets. Tsuna found her way to the 3rd engine and saw the enemies shoot at Captain America who fell of the side of the ship and was dangling from a loose cable.

With Thor

Thor runs into the detention section where he finds Loki, escaping.

"NO!" Thor charges at Loki who crouches down to attack, Thor ends up going through him into the cell. The fake Loki dissolves into nothing, the real Loki comes out from behind the cell door and locks Thor up.

"Are you ever not going to fall for that?" Loki queries.

In a fit of anger, Thor smashes Mjølnir against the glass which cracks slightly.

Loki smiles then heads over to the control panel, "The humans think us immortal. Should we test that?"

Suddenly, one of the enemy soldiers falls down, Coulson stands there, holding a Phase 2 prototype weapon.

"Move away, please," Coulson demands so Loki slowly raises his hands up and moves away from the control panel. "You like this? We started working on the prototype after you sent the destroyer. Even I don't know what it does. Do you wanna find out?" Coulson gasped in agony, he looked down and saw he was impaled right through the heart.

"NO!" Thor bellows in anguish.

Loki yanks his weapon out of Coulson who slumps down against the wall, breathing heavily. Loki heads to the control panel before giving his brother one last look. Without any hesitation, Loki hits the button sending Thor plummeting to the unforgiving ground below.

Loki shows no remorse as he looks down. He closes the hatch and proceeds to leave.

"You're gonna lose," a weak voice stated.

"Am I?" Loki questions, turning around.

"It's in your nature."

"Your heroes are scattered, your floating fortress falls from the sky...where is my disadvantage?" Loki inquires. 

"You lack conviction," Coulson replies.

"I don't think I-" Loki was cut off by Coulson who shoots him with the Phase 2 weapons which caused Loki to be blown through the wall.

"So that's what it does," Coulson mumbled to himself. He was dying, there was no other way to spin it. He wouldn't survive. No more life-risking missions, no more hanging out with Captain America... no more watching Tsuna grow up into the wonderful woman he knew she would become.

Coulson used all his remaining strength to lift his shaky hand to grab something from his pocket of his white shirt. It was a poorly crafted omamori charm, it was dark blue with a badly sewn kanji symbol for good luck. Tsuna made it for him a few weeks after she came to America, it was a gift of gratitude for convincing Kimura that Tsuna would be safe with S.H.I.E.L.D.

He remembers the day she gave this to him. She was so shy, hiding behind Natasha's legs but Tsuna toddled up to him and held it up for him to take, she stared up at him with those big, brown doe eyes filled with hope and it instantly became the most precious object to him.

'Sorry Tsuna.'

Tsuna's P.O.V.

At Engine 3

I sprung into action, I kicked one the shooters straight at the back knocking him forward and stumbling off the side, falling to his demise. The other two immediately start shooting at me so I flip backwards to avoid all shots. Natsu leaps off my head and lands on the face of one shooters and mauls at it. The other shooter was distracted by his ally's scream which allowed me to yank his gun before elbowing his face, rendering him unconscious. I whistled sharply, signalling for Natsu to jump off of the face of his victim which allowed me to deliver a roundhouse kick to his chin, he fell down like a sack of potatoes.

I whipped my head back, 'Uncle Phil?' Somethings wrong, I had a bad feeling, but I had to focus on this. Uncle Phil can take care of himself.

Just then Captain America managed to haul himself back up to safety, he stared at me in a mixture of disbelief and fascination. "Thanks," Cap throws his hand up in gratitude before he bends over, both hands on his knees and tries to gain back his breath.

"You're welcome," I replied, smugly, I just proved the great Captain America wrong. Victory never tasted so good. I moved back and stopped before peering out the gaping hole before dashing towards it, intending to dive out. Captain America's eyes widened once he realised what I was about to do so he jumps off the higher level where the red lever was to my floor and landed right in front of me, effectively cutting me off. "What are you doing?!" I demanded after screeching to a halt.

"I should be asking you that!" Steve exclaims.

"I can help with the Helicarrier!" I declared, determined.

"What? No. Head back to where it's safe," Steve ordered.

He was doing this again? Had nothing changed? I wasn't going to take this lying down, "Listen here, Captain. I'm not running away. Despite my age, I can help. I've been trained for the last 5 years because everyone in S.H.I.E.L.D. believes that I could be a hero! Is it so much to ask that you believe in me too?" I inquire, despondent. I clenched my fists tightly as tears steamed down my face.

Steve wasn't expecting that, was he really putting her down like that? He sighed before moving out the way, "I'm sorry about what I've said Tsuna, but I really do care about what happens to you. If you can truly help us then I won't stop you."

"Thanks!" I did a complete 180 on my personality. My tears had vanished like they never existed and I showed Steve a big, bright grin. "You don't need to worry about me since I have my gloves, Natsu and my dying will!" I exclaims before leaping out the hole. What a sucker!

3rd Person's P.O.V. 

Steve just stood there, shell-shocked, "What just happened?"

"The kid just played you good, Cap!" Tony guffawed over the earpiece. "Like mother, like daughter."

With Tsuna

As soon as I leapt off the Helicarrier, I activated my gloves and glide underneath the ship. I placed both my feet flat on the bottom of the ship, meaning that I was upside down, and used mist flames to create vines that wrapped itself around my legs to steady myself then used my sky flames to propel the Helicarrier so it would straighten.

"Argh!" I screamed, I was carrying the full weight of the Helicarrier by my legs and boy, was it heavy! My bones felt like they would shatter into dust, but I couldn't let up. Everyone was counting on me. Slowly, the Helicarrier was beginning to righten itself.

"Cap, I need the lever!" Tony warns.

"Got it!" Steve replies and pulls the lever, allowing Tony to escape before being shredded. I released my mist flames and flew back to the crater opening where Steve and Tony were waiting for me. As soon as I landed and stopped using my sky flames, I collapsed to my knees. I was completely exhausted. Steve held out his hand and helped me to my feet.

"Thank you," Tsuna breathed out.

Detention section 

Fury runs into the detention section, only to find his old friend dying against the wall

"Sorry, boss. The god rabbited," Coulson said as blood trickled out his mouth.

"Just stay awake," Fury requested, crouching down to his level. "Eyes on me!"

"No. I'm clocking out here," Coulson whispered.

"Not an option," Fury ordered.

"It's okay, boss. This was never going to work... if they didn't have something... to..." Coulson drew his last breath before he finished. Fury looks on grimly at Coulson. His friend was dead. The medical team arrives.

Fury was about to move away from Coulson's body when he saw a flash of gold so he looked at what was in Coulson's hand. It was that charm that Tsuna made most of them when she was younger.

Even though he would deny it vehemently, he kept the one she gave him. He had a soft spot for Tsuna even to this day, everyone did.

"Agent Coulson is down," Fury informs everyone over the earpiece.

"Paramedics are on their way."

"They're here," Fury discloses. "They called it."
