Richard was acting nervous and went over to his desk.

He pulled out the middle dresser and flipped it upside down so the bottom was facing up he took a letter opener and opened the bottom as he took out a file and put it in his bag along with a few other things. He ran to the chalk board that had equations and science on it as he erased most of it off. He picked up Peter and the Parker Family all made their way out to the car.

But what none of them know was that, tonight was gonna be the last night that Richard and Mary would see their son.

Chapter: 1 (Present Day)

15 year old Peter Parker was cleaning his closet when he stepped on a loose floorboard, he was confused because he doesn't remember any loose floorboard. So he got down and used his spider strength and pried the floorboard open and seen a bag with the initials "RP" and he knew right away that it was his father's bag, his mind flashed back to the night when his parents disappeared he remembered that his dad was carrying the exact same bag.

Peter swallowed the lump in his throat and carefully took out the bag and walked over to the middle of his room and sat on the floor. He opened it and see nothing but a file, Peter took the file out "What was my dad doing with his research." He thought, but he knew his father was a scientist but just didn't know where. That is until he reached in and found his badge and it said "Oscorp Industries".

He looked back and forth between the file and the name tag and it clicked, his father was working on some research for Oscorp. But if his father was hiding the file that mean that there is something in the research that couldn't end up in the wrong hands. He put the name tag down and reached into the bag again and this time he pulled out a recording.

He was so deep into thinking about his father's research that he jumped when his phone rang he looked to see it was Tony. After the Homecoming disaster they had gotten close, he answered and replies, "Hey, Tony."

"Hey, Kid want to come over I'm bored over here." Replied Tony.

Peter nodded and replies, "Yeah okay. You at the tower or compound?"

Tony replies, "I'm at the Tower kid."

Peter looked at the file and replies, "Okay I'll be right over, there's something I need to ask you anyways."

He hung up as he gathered all of his fathers stuff and put it back into the bag as he got up slipped his shoes on taking the bag with him as he walked out the door. He sent a quick text to May letting her know that he was going over to the tower. He was glad that she still didn't know about this other life because it would place her in danger.

While he was walking he felt his spidey-sense tingling a little as he held the bag tighter and walked faster. From what Peter put together whatever was in this file was related as to what happened to his parents and so that means he must be really careful to not alert anyone of his dad's research he found. Never know when your parents killer might still be looking for the research all this time.

When he finally made it inside the tower he let out a sigh of relief as he walked towards the elevator scanned his card. He went into the elevator and said, "FRIDAY is Tony in his lab?"

"Yes Peter and is waiting for your arrival." FRIDAY replies as the doors open and he stepped off.

He walked down the stairs and made it to the door of the lab, he punched in the code and the door opened as he walked in and says, "Hi, Tony."

Tony turned from where he was hunched over the workbench to look at Peter and says, "Hey, Pete." He saw the bag on his shoulder "What's that?" Tony mentioned to the bag.

Peter replies, "I...It was…..um….it was my dad's and I found some of my father's research and was wondering if you want to help me look through it?"

"Your Father's research? Why would you want to look through his research?" Tony replies, as he frowned.

Peter replies, "Because…...because i think it's connected to my parent's death." He made his way and sat down at the work bench across from Tony.

Tony's face softened at the mentioned of his parents but was confused at the same time wondering why would some research be related to the death of Peter's parents. "Okay, let's see what we got here."

Peter opened the bag and asked, "Do you know Oscorp Industries?"

"Yeah, I do. Norman Osborn is the CEO. Why? Thinking of transferring?" Tony replies, lifting an eyebrow.

Peter nodded and replies, "No, of course not, you know I prefer Stark Industries then Oscorp, i was just asking because, " He pulled out his father's badge and placed it on the table, "My dad worked there as a leading scientist in their latest research and i think that's what this is."

He pulled out the file as he placed the bag down on the ground. He placed the file down and says, "I think this has something to do with my parent's death. Because I remember a little of the night they disappeared. It was storming and i was looking for my dad, I looked in his study to see it was ransacked I called him and seen as he acted really nervous and grabbed this file from the bottom of his desk draw and erased some stuff from his chalk board, the next thing i know my parents were leaving and I was staying with May and Ben and they never came back."

Tony nodded as he listened to what the kid said, he said that his father was acting nervous and when someone is acting nervous means they had something to hide. "Did you look inside the file yet?" He said as he looked towards the folder.

Peter nodded and replies, "Not yet I wanted to tell you about it first because I don't think May knew that this research exists." Tony nodded as he moved over and sat by Peter as they both looked inside the folder and was stunned to see the title: "Araneus Oscorpeus" By: Richard Parker

As Peter and Tony read through the research and the file. They were stunned as Tony replies, "Now I know where you get your smarts." As they kept reading and one sentence that caught their attention : "I had merge my DNA within the Genetically Modified Spiders that I created."

Peter and Tony looked at each other as Tony says, "Maybe you being bitten wasn't an accident, maybe that's why it didn't kill you because the spider had your Father's DNA and you have his DNA."

"He also created the spider that bit me. But why was he so nervous?" Peter asked as he kept on staring at the same sentence they had read.

Tony sighs and replies, "Maybe there is something here that could be used as a weapon. Maybe that's why he was acting so nervous and maybe why your parents were killed, because Oscorp was wanting his research." Tony turned towards Peter placed a hand on his shoulder as he sighs, " Peter it looks like Oscorp was responsible for your parents' death." They kept on reading, reading, and reading. For the past hour they had learned a lot and figured out a lot.

"I also found this recording in his bag with his research." Peter said as he took out the recorder and pressed play as Richard's voice came through the speakers: "I have to disappear. I have to get as far away as i can. But as a father, it means I may not see my boy again. And, um, nothing is as Important to me as my son Peter. Nothing in this world. But i have a responsibility to protect the world from what I have created and to protect him from what i know Osborn is capable of. People will say I'm a monster…..for what I've done. And maybe they're right. I always thought that I'd have more time…...I'm sorry."

When the recording stopped they were stunned but Peter he was more than Stunned he had tears running down his face. Tony slowly looked over at Peter and seen the tears as he whispers, "Oh Peter." He hugged the kid who was quick enough to hug back as the kid cried on Tony's shoulders.

Tony didn't know what to think, what did he mean when he said He had a responsibility to protect the world from what he created." What did he mean by that? Tony thought to himself as he felt Peter calm down.

Once Peter was calmed down he let go of Tony and wiped his eyes saying, "Sorry Tony."

"It's okay Kid, it doesn't bother me." Tony said as he rubbed his hand on Peter's back for comfort.

Peter says, "What did he mean by what he created?"

Tony sighs and replies, "I Don't know Kid. I don't know."
