Umm this is well, just prepare for a really sad chapter :) (also the first parts weird but it's a nightmare so idk how else to write it)

Peter tossed and turned in bed, forehead and hands coated in sweat with a petrified look on his face. He shouted as the memories of what had happened not so long ago came flooding back once again in yet another nightmare...

"Mr. Stark I've got a really bad feeling about the mission today."

"It's gonna be fine kid nothings gonna happen."

Way to jinx it jeez...

"Okay kid i know there's a lot more guys with guns than we thought but it's gonna be fine, I promise."

"Just be careful Mr. Stark."

"I will Pete."

No you won't...

"Kid- kid look out!"

"Huh?"

"FUCK!"

Language, sorry not the time...

"TONY NO!"

"K-kid..."

"Tony... please I-I can't lose you too."

"It's gonna be okay Peter."

No it won't...

"I-I love you kid take care of the team for me okay?"

"Tony... don't leave me... please... DAD!"

Jeez so dramatic... sorry still not the time I guess...

Peter shot up out of bed panting and crying. The sobs wracked his body as he violently shook, tightly gripping what was left of his shredded sheets.

It didn't take long before Natasha and Bucky were at his side trying to calm him down. He was still a trembling and Natasha held him close and rubbed her hand through his curls.

"Shhh it's okay, it's okay, it's over." She whispered quietly. Peter pulled away and shook his head.
"I should've saved him... he died for me... he died because of me."

Bucky shook his head and pulled Peter into a tight embrace.
"It's not your fault Peter, you weren't the one that pulled the trigger."

Peter looked up to him with tears in his eyes and whispered so quietly they could barely hear it.
"Maybe not but the one who did deserves to die."

The two heroes quickly glanced at one another before deciding to ignore Peter's comment. The poor kid was grieving and everyone handled death in different ways. They weren't too worried about the threat.

Peter would never kill someone.

"Do you want to sleep in my room again tonight?" Natasha asked sweetly. After Tony died she sort of took on the motherly role for Peter and was doing her best even though being a mother was never in her training. Peter had been sleeping in her room almost every night since the mission.

Peter looked down and shook his head.
"N-no I'm okay, I'm just gonna stay here for tonight."
Natasha furrowed her brow but honoured Peter's wish. Her and Bucky stood up to leave.
"You know where we are if you need anything okay Pete?" Bucky said at the doorway. Peter just nodded in response and they left, shutting the door behind them.

Peter took a shaky deep breath and stood up. He threw on his suit, which he hadn't worn since that day. It still had blood stains on it from when Peter held his dying ment- father in his arms.

He opened up the window and turned back to face the doorway one last time.

He could never come back here... he couldn't bare to be a burden anymore. He couldn't be the reason anyone else died. He had to make things right.

And he knew exactly what he needed to do.

The name of the man who killed his father would forever be engraved into his mind. It was time that man got what he deserved.

"Karen, find Dennis Carradine."
(Bonus points to whoever knows who that is)

"Peter, your heart rate is extremely elevated, I do not think you are capable of making rational decisions at the moment, shall I call Ms. Romanoff?"

"No... just find him, please." Peter's voice was shaky, but it was laced with a tone that would make even the Red Skull himself crap his pants.

Karen didn't reply, but a route popped up and Peter was on his way. On his way to confront the bastard that killed his third dad.

It didn't take long for Peter to get there. It was a small, dirty old apartment in a very sketchy part of town. Peter didn't care enough for secrecy so he loudly smashed through the window.

It wasn't long before Daniel himself burst into the room Peter was in.
"What the fuck!?" He said with a toothbrush loosely hanging out of his mouth.

Peter didn't know what came out of him but all he saw was red. He charged at the man, repeatedly punching and kicking him until he was a wheezing heap on the floor.

"Who... who the-the hell are you!?" Daniel gasped out as he clutched his ribs tightly. He was leaning up against a wall and Peter was towering over him menacingly.

"You killed my dad. And now you're gonna pay for it."

The man gulped in fear. That voice was one of pure rage and agony, and those two things never mixed well together.

"Karen, activate instant kill."

Silence

"Karen I said activate instant kill, NOW!" Peter was even angrier now if that was possible. He just wanted this man dead.

"I'm sorry Peter I cannot do that."

"Why the fuck not!?"
(God the amount of language is horrendous)

"Mr. Stark instructed me to disable it in the event of his untimely death."

Peter's voice quieted at the mention of his fathers name.
"Wh-wha, why?"

Instead of Karen responding, a small hologram appeared in the center of Peter's mask. Peter practically fell over when he saw who it was.

"D-dad?"

The hologram smiled at him.
"Hey Pete, so if you're seeing this it means something bad happened and well.. I'm gone and you're not taking it well. Listen kid, whatever happened I know it wasn't your fault. The only reason you're doing whatever stupid thing it is you're trying to do is because you blame yourself for what happened to me."

Peter's breath shuddered as the tears began to flow down his cheeks. The message continued,

"Kid, I took away your instant kill because I don't want you to do something you'll regret while blinded by anger. You're a good kid Pete, the best kid actually and I would hate to see you lose yourself because of me. I know Spider-Man doesn't kill, but neither does Peter Parker and i don't want that to change okay? I can't imagine how hard this must be on you if you're willing to break your no killing rule, but i promise it'll get better, you still have the team and they need you kid. I love you Pete and maybe I'll see you again one day if i didn't go to hell. God i hope I didn't end up in hell..."

The hologram slowly disappeared and Peter was a sobbing mess on the ground. He took a deep breath, pulled himself together and walked over to the struggling man against the wall.

"Ya know, I came here to kill you. But now I know that if I kill you I'll be no better than you of any of the other criminals I swore to protect the city from. I won't let myself become like you. You deserve to rot in prison for what you've done, and I'm going to make sure of it. You're never going to hurt anyone ever again."

The man had no time to reply before he was encased in a web and dropped off at the local police station and immediately taken into custody.

Peter swung back to the tower, knowing that he had done the right thing. He went through his window and saw a pacing Bucky and Nat standing in his room. When they saw him the rushed over to him, checking for any injuries.

"Oh my god, kid, what happened?" Bucky said after he found no injuries on the boy. Peter sighed and pointed to the bed. The three sat down and Peter began to explain.

"I-I lost it... I couldn't handle the weight of Tony's death anymore a-and I thought if I killed the man that killed him I would feel better."

Nat and Bucky shared another panicked look but Peter noticed and shook his head.
"Don't worry I didn't actually do it. Well I tried, but Mr. Stark stopped me."

Now the two were even more confused. God now the kid was hallucinating too?
Peter chuckled at their reactions.

"I tried to activate the instant kill feature in my suit but a recording of Tony popped up and I snapped back to my senses. I captured the guy and brought him to prison."

Natasha pulled Peter into a tight hug which he returned and Bucky soon joined in as well.
"Thanks for being there for me guys."

Bucky smiled and nodded.
"Of course kid, we're family."

Tony looked down from the skies at the sight in front of him. A warm feeling filled his chest as he watched his son with his family.
"Looks like I'm gonna see you again after all kiddo."

Tony smiled as a bright white light surrounded him and he could finally be at peace knowing that Peter would be okay.
