The team is: Tony, Steve, Natasha, Clint, Bruce, Thor, T'Challa and Shuri is with them.

"Guys, FRIDAY is unresponsive. Does anyone have eyes on the men in the building?"
Tony Stark aka Iron Man asked into his comms.

"I am fighting 30 agents on floor 22."
T'Challa said.

"I've got about 20 agents here with me. I'm on the 69th level in room 42."
Cap said into his comms.

"Hah, 69."
Clint Barton aka Hawkeye giggled into the comms.

"Stop acting so childish Clint."
Natasha Romanoff said.

"Yes Barton, stop acting so ish of child."
Thor boomed.

"Guys can we focus on not letting HYDRA take over the tower and not on Clint being his usual self."
Cap said into the comms.

"Hey!"
Clint shouted.

"Ah fuck. They somehow managed to override my suits. We need to fall back!"
Tony shouted into the comms.

"Meet on the roof. We will go to a safe house."
Cap told the team.

"We can't, remember S.H.I.E.L.D is overrun by HYDRA agents and they have the locations of all safe houses."
Clint said.

"I know a place. It's safe and it's not on the records at S.H.I.E.L.D."
Natasha said.

~~~~~~~~~~~~~~~

The team arrived to a small forest and walked in. T'Challa was grudgingly carrying Shuri on his back, Natasha and Clint were up ahead, Steve and Tony were trying to have a civilised conversation and Bruce and Thor were talking about what plants grow on Earth and on Asgard.

"Why are we in a forest? We are meant to be going to a house, Romanoff, not a silly tree house."
Stark whined.

"Just wait."
Natasha said.

"Wait, are we going to you-know-where?"
Clint asked excitedly.

"Yes. And before you ask, no he's not home. He's on a trip and won't be back til later tonight."

"Awww. That's no fair."
Clint pouted.

The team continued walking until they saw a house in the clearing.

"Race you."
Clint said before running into the house.

"I swear he's a little child."
Bruce said.

They heard a scream from the house and Natasha rolled her eyes.

"James, no threatening Clint. He's my only friend!"
Natasha shouted at the house.

"But that's not fun."
A voice that was familiar to Steve said.

The team went into the house to find a Clint tide up in a net and a man with long hair laughing.

"Nat, your husband is trying to kill me again."
Clint whined.

Natasha cut Clint from the net and kissed the man with long hair.

"James you got to stop threatening people every time they come to the house. You nearly killed Pete's friend."

The man tied his hair into a bun and Steve stared in shock.

"B-Bucky?"
He asked.

"Steve?"

Steve went and hugged Bucky.

"Wait. Is the assassin your husband?!"
Tony asked shocked.

"Yeah, we got married a couple of years ago. Sent you an invite but you didn't respond."
Natasha said.

The door opened and a voice said:
"This is how I enter my house. WHATS UP FUCKERS?"

Shuri recognised the vine and the voice.

"Why do you have my phone?"

"Cos fuck you that's why!"

[There should be a GIF or video here. Update the app now to see it.]

The voice came into the living room and crashed into Natasha.

"Mama! I thought you were coming back next week!"

"I thought you would be more happy to see me earlier. The Tower was under attack so I had to take the team here."

"Is Uncle Clint here?"
The boy asked.

"Why don't you find out."
Clint said before the boy hugged him.

Clint let go of Peter and he said hi to Shuri.

"Hey Ri-Ri."
Peter said.

"Hello Beter."

"How do you know the Princess?"
Bucky asked.

"Oh I know the Princess because she's the person I'm always messaging on Vine and I recognised her voice when she finished the vine."
Peter said.

"Right, we're all tired so where are we sleeping?"
Tony asked.

"Shuri can sleep on one of Peter's bunk bed, Clint can stay in the same room he always does and T'Challa can bunk with him. Thor and Bruce can stay in the other spare room and Tony and Steve can stay in the living room."
Natasha said.

"I call top bunk!"
Peter shouted.

Peter and Shuri raced up the stairs.

"I'll show you our room, roomie."
Clint said to T'Challa.

"Do not call me roomie."
T'Challa said.

"I'll show you guys to the room."
Bucky awkwardly said to Bruce and Thor.

~~~~~~~

Shuri was woken up by someone crying and vomiting.

"Beter?"
Shuri asked into the bathroom next to their room.

"I'm fine Ri-Ri. Can you get Mama or Papa or someone please?"
Peter said before vomiting into the toilet.

"Ok."
Shuri raced out of the room and banged onto the first door she saw.

"Hello? Please help?"
Shuri shouted.

A grumpy Bucky opened the door.

"What?"
He grumbled.

"Peter is spewing and crying and I don't know what's wrong."
Shuri cried out.

Bucky ran out the room, passed Shuri and went into the bathroom where Peter was spewing his guts out.

"Peter, it's Papa. Are you sick?"

"I-I don't know. I was feeling fine this morning but at the field trip I got bit by something and then I came home, fell asleep, woke up and started spewing."
Peter said before spewing again.

"It's all right my little baby. Do you want me to get Mama?"
Bucky asked in Russian.

"Yes please Papa."
Peter said before spewing into the toilet.

Bucky got up and went to his room.

"Natalia? Peter is spewing and wants you."
Bucky said.

"Just coming James. What happened?"
Natasha asked after stumbling out of the bed.

"He said he got bit by something on his field trip and he said he felt fine until he fell asleep."
Bucky explained.

Natasha went into the bathroom and kneeled next to Peter.

"Peter, do you know what bit you?"
Natasha asked him.

"I think it was a spider, Mama. One of the radioactive spiders escaped and it must have bit me."
Peter said after spewing.

After 30 minutes, Peter finally stopped spewing.

"Come on baby. Let's get you back into bed."
Natasha said.

Peter tried to get up but his hands were stuck to the toilet.

"Mama, what's happening?"
Peter asked with fear creeping through his words.

"I don't know but don't panic. I will get Shuri, Stark and Banner to check what's wrong with you tomorrow."
Natasha said after prying Peters hands off.

"Can I sleep with you and Papa please?"
Peter asked.

"Yes my baby. Let's get you in clean clothes and we can have a family hug. Does that sound good?"
Natasha asked.

Peter nodded and stumbled into his room to find Shuri pacing around.

"Beter, are you all right? What's wrong?"
Shuri asked rapidly.

"I don't know Ri-Ri."
Peter shakily replied.

"Go to sleep Ri-Ri, I'm sleeping in Mama and Papas bed."

"Ok Beter."
Shuri climbed into bed.

Peter got into clean clothes and climbed into bed next to Natasha and Bucky.

"Night Mama, night Papa."
Peter said before going to sleep.

~~~~

The team managed to get HYDRA out of the tower and defeated them with the help from a new spider themed hero. At least, they thought they had defeated HYDRA.

~~~~~~~~~~~~~~~~~

It was a year after HYDRA took over the tower and the rest of the team met Peter. The Avengers all fell in love with Peter immediately and visited him as much as they could.

~~~~~

"Where is Peter?"
Natasha asked after she got home from a very long mission. Usually when Natasha was away for a long mission, Peter would be pacing by the door to ambush her as soon as she got in so she was very worried.

"He's gone Natalia. He's gone. He's been missing for three weeks. I tried to contact you. The Avengers tried to help but they couldn't find him."
A red-eyed Bucky said.

"No! Nononononono! This can't be happening!"
Natasha broke down.

"We will find him Natalia. We will."
Bucky tried to reassure her before breaking down.

~~~

"Now, tell us where Natalia Romanova and James Buchanan Barnes live or this will be much worse."
An agent snarled at Peter.

"I-I will never tell you where Mama and Papa are. Not even if you try and torture me."
Peter managed to say before screaming with pain.

"Tell us!"
The agent screamed at Peter before whipping him.

~~~~~~~~~

Peter's back, legs and arms were bleeding heavily after the agent left the room. He crawled up into a ball and tried to sleep. He kept thinking about his Mama and Papa and his new extended family.

He started silently crying. He missed his family.

~~~~~~~~~

"Natasha, calm down. We will get Peter back."
Nick Fury tried to calm the mad Russian spy.

"He's my son Fury, I need him back!"
Natasha broke down and started crying.

Fury awkwardly placed a hand on Natasha's shoulder.

"Don't worry Natasha, we will find him."
Fury softly spoke.

~~~~~~~~

"We have a possible lead as to where Peter might be."
Fury said at the next meeting.

"Where? Where the fuck is he Fury? I want my fucking son back."
The redhead said.

"We believe he's in Russia. Near the border of Russia and Norway."
Fury simply said. (I did research fuckers)

"Let's go fuckers. We are getting my son back."
The redhead spoke before running out of the room.

~~~~~~~~~~~~~

"Tell us where Natalia Romanova and James Buchanan Barnes are or I will put this blade through your head."
The agent said.

"G-go to hell."
Was all Peter managed to say before passing out.

The agent grumbled and stormed out of the room.

~~~~~~~~~~~~~

Bruce, Natasha, Bucky, Steve, Tony, T'Challa, Clint, Thor, Wanda, Vision, Sam and Shuri were all on the jet headed to Russia. They were getting Peter back, no matter how impossible it seems.

It seemed like a thousand years before they got to the Russia-Norway border.

"Right, Nat, Buck, T'Challa, Sam, Wanda, Stark and I will check the base. Everyone else, will check the forest. Got that?"
Steve said.

"Shuri you are staying on the jet. I do not want to see you on the ground."
T'Challa told his sister.

"Fine brother."
The girl whined.

Everyone else stepped off the plane and headed off to where they were told to search.

~~~~~~~~~~~~~

"Did you get the information?"
The commander asked.

"I'm afraid not sir. He passed out before we got the information sir."
The HYDRA agent spoke.

"Place him in ice water. He will soon wake up."
The commander said.

"Hail HYDRA!"
The agent shouted.

"Hail HYDRA!"
The commander shouted back.

The agent walked to the cell where Peter was being held and another agent walked into the office area thingy. (I dunno what to call it)

"Sir,  the Avengers are here. I think they have found where we are holding the boy."
The agent spoke.

"Kill them. If you can't, kill the boy."

"HAIL HYDRA!"
The agent shouted before shouting out orders to the rest of the agents.

~~~

"Shitty sticks. They know we're here!"
Stark shouted.

"Language."
Natasha spoke into the comms.

"Why are you saying language?"
Bucky asked.

"Steve said it once and now everyone says it."

"He's such a hypocrite. He swore worse than sailors back in the day!"

"Rogers, why is James telling me that you swore worse than sailors?"
Natasha shouted over to Steve.

Said man blushed.

"Shut up Bucky."
He muttered.

~~~

Natasha and Bucky got to the last unopened door in the base. They had started to lose hope that their son was here and were also doubting if he was even still alive.

"Together?"
Natasha asked.

"Together."
Bucky repeated.

They both opened the door and at first glance it seemed empty but in the far right corner there was a pair of eyes watching the two ex-HYDRA assassins.

"Mama? Papa?"
A voice croaked out.

"Peter, is that you?"
Natasha asked, hopefulness leaking through her voice.

"Yeah. Oh god it's been ages."
Peter crawled down the wall and hugged his Mama and Papa.

"So you're the little spider who helped us last year?"

"Yeah. I'm sorry Mama."

"Don't be sorry Pete, we are very proud of you,"
Bucky said.

"We got him."
Natasha said into the comm.

Decided to update. First update of the year and it's February.
