After internally arguing for 15 minutes, he made up his mind. He needed to get his mind off of May. Peter looked down at his mess of a Spider-Man suit, now dirtied with traces of vomit and tears. He slowly changed into a sweatshirt and jeans. After drowning in his emotions since the phone call, he felt numb. The worst part was, he didn't even care. He was almost relieved, desperate for anything to stop the pain in his chest of never seeing May ever again. He'd rather feel like everything in the world was muted. Like the world was just going on around him and he was stuck. Anything was better than his grief.
He grabbed his Stark Phone (a gift from Mr. Stark, of course) and a wad of cash that he fished out of his dresser and got a taxi to take him to the Avengers Compound upstate. Looking back, Peter knows he should've just went to Stark Tower which was only a train ride away, but he wasn't thinking straight at the time and the thought of having to sit on the train and hold it together in front of so many people was sickening to him.
Peter didn't speak at all for the hour and a half ride. He put in his earphones and blasted music that was way too loud for someone with normal hearing, let alone his enhanced senses. Nothing mattered anymore. Not when he was here. Not when May wasn't.
Peter handed the money to the driver, who Peter had asked to drop him off half a mile before the compound so the location wasn't revealed. Peter didn't care if there was any change, he turned to start walking towards the compound almost robotically. It didn't matter to him anymore.
It took Peter 45 minutes to get to the entrance due to his sluggish pace. He used his entrance pass that gave him full access to the compound. Peter walked in, and he saw out of the corner of his eye a very startled Happy Hogan, interrupted from speaking to a group of other Stark Industries employees that Peter recognized, but he didn't stop to even give them a passing glance. He made a beeline for the staircase, forgetting that the elevator even existed in his disheveled state, walking as fast as he could so nobody would come after him. He returned to his sluggish pace the moment he was sure nobody had come to follow him or talk to him.
"Sir, Peter Parker has entered the building." FRIDAY stated in a calm voice. Tony Stark looked up from the wire he was fixing for a new prototype of the Spider-Man suit.
"What?" He asked. Peter? What was he doing here? How did he even get here?
"Peter Parker has entered the-"
"No, I know he's entered the building, Fri," Tony said. Boy, was he thankful for coffee as he took another long sip of it. He hadn't slept for over 30 hours but needed to complete the suit first. "Do you know why? What's wrong? Where is he going?"
"He seems to be making his way towards his floor, but he's using the stairs. Sir, I advise you to alert him that the Avengers are present and running into them could jeopardize his entire identity. Keeping secrets is not something that the team tends to take lightly, sir, and I predict that Peter will pass the lounge on his way to his floor. The Avengers are in the lounge as well."
"Wh-" Tony's spluttered and eyes widened as he spit his coffee all over the lab floor. "DUM-E, clean that up." The robot whirred to life in the corner. "Fri, take me to the Avengers lounge." Tony added as he smoothly stepped into the elevator.
He worried what might happen if Steve found out about Peter. He wouldn't be happy knowing he took a fifteen year old kid onto the battlefield… come to think of it, they would all probably hate him. Nat would most likely slice his balls off. He knows she hates kids in battle since she was trained to be a spy when she was a very young child.
"Shit shit shit shit," Tony repeated as the elevator opened. But he was too late. He just saw Peter walk into the room, faced streaked with tears and eyes puffy and red from crying. Wait-crying? The Avengers saw him too, but Tony didn't care about that right now. He was only concerned for Peter. Was he hurt? Who hurt him? What was wrong?
Steve jumped right up from the couch and walked over to Peter, who he had never seen before. Peter made eye contact with Tony for a split second as if to say, "I'm sorry," then averted his eyes to the super soldier in front of him with a panicked expression.
"Son, what are you doing here? How did you break in? Who are you?" Steve interrogated. Once Tony processed what was going on, he stepped in.
"Nope, it's fine, I got it, he's just an intern that I called in to help me with my suit prototype, right kid? C'mon, let's go," He said approaching Peter quickly and putting an arm around his shoulder to guide him out of the room.
