Dad's here
 
 
 
While waiting Peter find himself lying in his own pool of blood. Staring at the web he created about 15 ft above from where he was. Slowly dissolving and dropping threads over his face.
He can't move his leg now, nor his arms.
 
The sun is setting and the clouds didn't clear up. The sky getting darker and Peter knew he won't last long at all.
He didn't know how long was he there. Getting in and out of consciousness. He blinks slowly tears falling down the side of his face. He takes in careful breaths that's now hurting his chest. Ribs.. or whatever it was it hurts.
 
"I don't think I'm.. going to make it.." He mutters to himself. Wanting to sob but he can't even do that.. he blinks and blinks slowly he did until he hears the familiar sound of repulsors.. and the colors he didn't know he'd miss so much.

 
"Peter!!!!" His blurred vision saw red and gold and he sobs.

"Dad.." He calls out but no more voice came out. He smiled, relief flooding through what blood left in his body and that's when everything stops.
 
No..
 
Dad..

"Pete! Peter!! Son.. son.. wake up. No.. No!!! Bruce!!! Get down here now!!! Now!!!!" Tony jumps out of his suit knowing he can't even lift his son, afraid to break him even more. He looks up where the Quinjet was floating above them. Clint and Natasha came down so fast with a portable stretcher and with Bruce and his medical team.
 
"Bud, we got you. Dad's here.. I'm here. Right here kiddie. I'm just right here." Peter could still hear him but he can't respond anymore. Even a lift of a finger. Tony held his hand gently and Peter felt those hands of his father tremble and how cold they were.

"Get out of the way Tony! He's not breathing!!" Bruce pulls him away while one doctor push him and started doing CPR and Tony froze.

Clint helps the doctor pumping air into Peter's mouth and nose from a resuscitation bag. Natasha then pulled Tony in her arms as Tony still frozen shock. Staring at his dying son. With arms shaking slowly held onto Natasha. His hands grip her leather jacket like a lifeline.
 
"Nat.. my son.." His voice trembles.

"I'm sorry Tony.. I'm so sorry!" Natasha cries out hugging Tony trying to turn him away but he was unmoveable. Tony froze from where he was kneeling down. Watching the scene of his son slowly slipping away.. going to a place where he could never get him back. He cannot let that happen.
 
"Pete.."

"Airways are clogged! Move away!" The Doctor yells out carefully pulling Peter to his side as he vomit blood and acid out of his lungs and stomach. Finally letting him breathe.

"We got him back." Bruce said and it didn't register to Tony as they carefully lift his son, Steve helped strapping Peter in the orange stretcher.

"We need to operate in the Quinjet or he'll not make it." The Doctor said and Helen Cho was already waiting in the Quinjet prepping for operation.

"Lift him up carefully!" All was going way to slow for Tony and Natasha was talking to him but he can't hear her. Something about they need to go now. Peter needs to go now.

He can't hear them. All he hears is a long deafening ringing sound in his ears. His eyes glued on the blood on the ground where his son was and now Steve pulling him up to his feet.

"Snap out of it Tony! Peter needs you! Let's go!" Steve forcely pushing him in his suit and Tony nods still in trance. He can't feel his body. All he feels is the coldness. Like he is submerge in an icecold bath.

His son is dying..

He couldn't go there again. He can't lose his son.

"Pete! Pete.. bud, hold on. Don't let go bud. I gotcha.. I'm here."

"Sir, we need you out!" The Doctor said but Helen stops him.

"You won't win." Helen said to the Doctor and Helen throwed scrubs over to Tony.

"Wear that if you're gonna stay in here." She said and Tony moved fast and held his son's hand in his. Kissing his pale hand. Cold. Bloodied hand.

"Buddy, I'm here. Pete.. I love you kiddie. Don't let go, bud. Please... Please don't leave, Dad. Don't leave your oldman like this." Tony begs as he cried watching the Doctors place an intubation in his mouth watching not even a little struggle from his son. He didn't even need to be put down. He's out and looking at his pale and lifeless son will be forever in Tony's nightmare. He closed his eyes and waited until all the preparations are done and the only thing that calm Tony was the sound of the heart monitor. His heart is beating and that's all that matters.

"We'll start, Tony." Bruce said helping out with the operation. Tony could just nod with a cloth separating them. Shielding Tony of what trauma he could have more. Seeing his son being cut open might make him hurl.

"Pete.. just hold on. Hold on.. Don't let go of Dad's hand okay? You can't do that to me bud. Please.. Please son.."
Tony wipes his eyes kissing his son's forehead, gently combing back his curls. Wincing at the sight of dried blood all over his face. His head was bandaged from the back where he hit his head.

"We need more blood here!" The nurses are running in and out of the OR until Natasha and Clint came with a blood bank cooler. Bruce quickly grabbing a few bags of blood and running back.

"We need to finish now before landing to the medbay." Helen said as the other doctor double up the blood transfusion.

"Tony.. we're almost done.." Tony cannot even comprehend what Bruce was telling him. All he knows is that his eyes are on his son and sometimes on the heart monitor right in front of them.

"Buddy, you're doing great. Just hold on. Just a bit more." Tony squeezes his hand and then suddenly Peter squeeze back making Tony shot back, eyes on his son's hand that's now gripping his.
 
"Bruce!" He smiles knowing his son's going to be okay now but that same moment Peter's hand holding his became lax. Then there's that loud ringing in his ears again.
 
But this time... It was different. It's not in his ears only.. the loud ringing echoed in the whole room. 
 
"Cardiac arrest!! Move!!!" Tony's face falls. Bruce was pumping Peter's chest then someone yells.

"Clear!" Clint and Steve were already pulling Tony away from Peter who just got shock by the defibrillator.

"C'mon Peter!!" Bruce was now pumping his chest.

"Pete.." Tony froze staring at his son.. then his hand.

He held my hand..
 
He just held my hand tight. 
 
"No, why are you letting go kid? No.. No!! NO!!!" Tony screams trying to run back to his son but Steve quickly caught him before he even lays a hand on Peter just as soon as Helen shocked him again with the defibrillator.

"No.. please!!! Not my boy! Pete!! Son!! Peter!!!" Tony struggled, kick and punch Steve and then Clint but it was no use. He fell on his knees with Steve and Clint holding him in a vice grip. Natasha on the other hand was against the wall, both hands over her mouth as she held back her sobs.

They carry on doing that for the longest 15 minutes of Tony's life.

"One More!"

"Bruce.."

"I said One more Helen!!" Bruce kept on pumping the boy's chest waiting for a signal to let go so she can shock him again but Helen just kept the defibrillator to the side. Turning the machine off.

"Bruce..."

"Helen!! Keep going! We have to.. we can't just stop. We can still save him!" Bruce kept pumping but Helen just shake her head.

"Bruce.. let's stop.. he's not responding. Blood pressure is too low. His heart stopped 20 minutes ago.. we have to stop."

"Pete.." Tony stood on shaking legs.. without comprehending what Helen was saying.

"It's hemorrhagic shock.. he loss too much blood and we weren't able to replenish him in time.. it's too late."
One Doctor grab his filer.
 
"Time of death.." he says and Helen looked at her watch.

"5:46pm.." She says.

"No.. don't say that.." Tony shakes his head feeling like he was submerge into ice cold water.
 
"Not my kid.. of course not." Tony stumble on his way back to his son. Cupping his cold pale cheeks.

"Pete, buddy.. wake up. It's okay, kid. I got you.. I got you buddy. Your Dad is here. Wake up! Or I'm going to turn the sprinklers on Bud. Don't do this to me, Pete.. It's not funny, son.."
 
"Tony.." Bruce was still pumping but the other Doctors are stopping him, he yells out, Hulk coming out in a second scaring the Doctors who fell back.

"NO!" Hulk yells out and Bruce Banner takes over again, pumping his Nephew's chest.

"No.. No way, he's dead! No one is pronouncing death here!! No one!" Bruce persisted.

"Peter c'mon.. don't get me angry here. I can't lose you kid. Pete... Pete.. my boy.. please not my son.. please.." Tony sobs and then he finally breaks.
Screaming out in agony.
 
"Ahhh!!!!!" And the steady Quinjet move a bit as if it hears his owners agony.

"NO! NOT MY KID!! NO!!!!!" He cries out and Clint tried to pull him away but to no avail Clint just stayed still until he falls on his knees as well. Crying silently with his hands clench tight.
 

"PETER!!!!!!"
 
 

 
"Peter!!!!!!"
 
Peter turns his head around towards his back. He's sitted at the wooden dock, his feet submerge in the water. Water that's surprisingly warm.

"Dad?" He thought he heard someone. Someone sounded so much like his Dad.

"No way.. Dad is dead." Peter smiles to himself.

"Hey Petey!"

"Uncle Ben!" His Uncle sat next to him wrapping an arm around him.

"I missed you, Pete."

"Me too." Peter leans in and he sighs at the warmth.

"How about me?" A familiar voice made Peter look up.

"Aunt May!" Peter almost stood up but May sat by his other side hugging the boy she missed so much.

"Oh sweetie. I missed you so much."

"I missed you too, May." Peter was not crying he was filled with joy and warmth.

"Why are you here? What happened?" May asked cupping both side of her Nephew's cheeks.

"Huh? We were on a fieldtrip" May and Ben shared a look and they both hug the boy. 

"Pete, Listen.." Ben asks ruffling the boy's hair making Peter chuckle.

"To what?" Peter then started kicking his feet in the water singing and humming an italian song. A lullaby.

"Who.. who made that song?" He stops asking himself. He knew he never listen to any italian songs ever. May didn't like music in that genre let alone in that language.
 
"Kid!! My boy... Pete.. please wake up.." 

What? Wake up?
 
"Who? Is that you, Ben?" Peter eyed his Uncle and he smiled at him, kissing his Nephew's forehead.

"Hun, not yet. We missed you greatly but not yet. You will make that person grieve too much he'll blame himself for the rest of his life." May said kissing his cheek.

"That person?"

"I guess you found someone who'll take good care of you, Pete. I'm so happy. May had been talking about him and how you two got along so well. Knowing that, she was able to pass on without worries." Ben said and Peter's eyes widen.

Pass on? Did I.. died?

"W-What happened to me? Who is that Man calling me?"

Peter looks behind them again. Pulling his feet out of the water. He stood up and eyed the place where the voices are coming from. A Cabin. A very familiar Cabin. May and Ben stood up with him.

"Who..?" He then shrugs, stretching out his arms, staring at the sky.

"It's no one right? I want to stay here with you guys." Peter hugs May and she sighs.

"It's so bright and warm. I can stay here forever.." Peter takes in a deep breath he was about to sit back down but he stills.
 
"Kid no!! No!!! NO!!! PLEASE!! Dad is here!! Right here!! Come back!!!"

"Come back?" Peter heart aches. Who is.. that?

"What? Why am I crying?" He felt his cheeks got damp. With tears he didn't feel falling. 

"Pete.. your Dad is waiting for you. You can't go yet. Not yet, sweetie. It's too soon." May is crying as well but she's wiping Peter's cheeks and not hers.
 
"My what? I don't have a.."

"Dad's here, buddy! Right here.. comeback to me kid. Pete.. please.. please.. Don't do this to me kid.. please.."

"Dad? Dad!" Peter calls out and Ben walks first. Dragging his Nephew's hand.

"Go, Pete. We'll see each other again but not like this."

Peter jumps up and hugs Ben and May joins in.

"I missed you guys so much.." Peter sobs. "But..but.."

"It's okay, Honey.. Go back to him. He needs you." May said kissing his cheek. Smiling at him.

"May.. I love you May.. I love you Ben.. I'm sorry.. I'm so sorry.."

"Shh.. It's not your fault.. you're doing great, Pete." Ben rub his back looking proudly at his Nephew.
 
"No.. NO!! NOT MY SON!!! PETE PLEASE!!! My boy.. not my boy.. oh God.. please no.." the voice begged and begged him.

"Dad!!" His walks turn to running and he found a Cabin right in front of them by the end of the wooden dock. He opens the door but he stills taking last looks from his Uncle and Aunt.
 
"Go.. We'll see each other again, sweetie. No rush though. Take all the time you need." May smiles and he smiled back.

"We love you so much, Petey." Ben said smiling as well.

"I larb you, sweetheart." May said making Peter sob, wiping his eyes with his arms and he waves good bye to his 2nd parents.

"I love you guys too."

"Go.." they both say to him and he nods.
The moment he goes in he fell into darkness.

"Ahhh!!!!"
 
"Peter!!!"
 
 
 
 

 
Bruce was exhausted and the moment his rhythm fell his knees gave out and he fell back sobbing.

"No.. No way.." he cries out.

"My boy.. my son.. come back Pete.. come back.. I'm right here, Pete. Dad's right here." Tony sobs kissing his son's forehead, staring in a sobbing mess at the pale skin of his son.
 
"Pete.." Tony felt so lost..he didn't know what to do at all. Not anymore..
Did he really loss his son?
This fast?
 
That's it?
 
Just like that?
 

"I'm going to take the intubation out.." The other Doctor said after everything went quiet. Even the heart monitor was turn off. Tony was sitted back on the stool next to his son. Holding his hand. He watch with dead eyes as the Doctor takes the tube out of Peter's mouth. His son unmoving. Pale as a sheet of paper. Blue lips and slightly parted with no air coming out of them.

 
No more help. No more breathing..
 
His son is gone.. how can he accept that now? He will never accept it.
 
"I'm so sorry Tony." Helen said but Tony didn't heard her. He was still staring at his son's lifeless body. Trying to wipe away the dried blood off his cheek.
"Pete.. let's go home bud.." He says.
 
Tony was about to let his son's hand go but it didn't budge.
 
"It's too soon for rigor mortis.." Helen mutters seeing how Tony can't pry off his hand.
 
 
"D..Dad.."

"Pete..?" Tony leans in double checking if what he heard came from his son.
Then he hears it.. breathing.
 
Just a bit.. so shallow.. then his son's brown eyes opens slightly..
 
"Dad.." His son.. Peter just called him. Voice so quiet you can almost miss it if you didn't listen.

"Make way!!! Shit!" Everybody was panicking placing back the monitors and everything. The blood transfusion was still pouring in even when they stop the CPR.
 
It took awhile but Peter was able to absorb the blood just in time.
Or Peter was really called back by his Dad..
 
Tony didn't hear anything anymore. He's just a sobbing mess, smiling from ear to ear. Sobbing loudly while his eyes fix on his son. 

"Bud.. you're in so much trouble for scaring your old man like that. You know I have heart problems right?" Tony's voice is shaking. Peter stares at his Dad, gripping into his Dad's hand.

Bruce placing back a normal oxygen mask over his face.

"Welcome back kiddo.." Bruce said sniffing and wiping his face with a shaky and cold hand.
 
Peter couldn't reply back to Bruce but he did felt his Dad kiss his head multiple times singing him the italian lullaby until he falls back to sleep. This time with his heart monitor loud and clear as day.. telling everyone he's alive.
 

The Quinjet finally lands in the landing pad at the Avengers compound.
His Dad never let his hand go even once.
 

"Dad's here.."
