A/N: After I saw Endgame, all these story ideas started bouncing around in my head. Five years is a long time, and I wanted to explore not only the characters who survived the original Snap, but also what life was like for those who had to rejoin the world after being gone half a decade. So I decided to put them all together in a series of one-shots. These will center on various characters and take place at various points in time. Obviously, major spoilers lie ahead.

"Summer has come and passed
The innocent can never last
Wake me up when September ends
Like my father's come to pass
Seven years has gone so fast
Wake me up when September ends."
-Wake Me Up When September Ends, Green Day

Peter Parker
(Immediately post-Endgame battle)

Once the dust had settled and the shock had lifted enough to allow for rational thought, Peter realized he needed to call his aunt. Problem was, he had no idea what had happened to his phone. He thought he might have left it in on the school bus, what felt like yesterday but was apparently five years ago.

He shook himself before he dove too deeply into that rabbit-hole. He could absorb the time jump later. Dazed, he wandered past the blue guy and the girl with antennae. He wasn't even sure they would know what a phone was. A loud roaring made him look up as a quintjet slowly descended on the battlefield. He stumbled toward it as others rushed out with medical kits.

"Do you have a phone?" he asked the first person he came across, a woman with a long ponytail and a no-nonsense expression.

"Are you injured?" she asked brusquely.

He blinked. "What, no, I…"

She cut him off. "We need to take care of the wounded."

Peter felt tears welling up in his eyes. "Please, I need to call my aunt…"

A voice interrupted them. "Hill. Give the kid your phone."

Peter looked to the left to see a tall man with an eyepatch staring directly at him. He had no idea who this guy was, but he must have been somebody important, because Hill immediately handed over her cell. Peter almost started crying again when he recognized it as StarkTech. With shaking fingers, he dialed.

"Hello?"

His aunt's voice had never sounded more beautiful, and a gargantuan lump formed in Peter's throat. "Aunt May?"

There was a sharp intake of breath. "Peter?"

Peter nodded, then realized she couldn't see him. "Yeah…it's me."

"Oh my God." His aunt was crying now. "Oh, thank God. Where are you? I'll come get you, wherever you are, sweetie."

He looked around at the ruined landscape. "I'm at the Avengers compound, but you might have some trouble getting here. There's been a battle."

His aunt took a moment to process this. "I don't care. I'm coming, I'm on my way."

"Peter." A familiar voice brought his attention back toward the jet, and he sucked in a breath. Happy Hogan pointed to the phone. "I'll take you home."

Peter nodded. He couldn't take his eyes off Happy. Did the man know?

"May, Happy's gonna bring me home, okay? I'll be there soon. I love you." He hung up before his aunt could argue.

"Come on, kid." Happy's gentle voice made Peter's eyes sting again.

"Happy, Mr. Stark, he—"

"I know." The man's face was set in a grim line, and the ensuing silence followed them into the car and all the way back to the city.

It wasn't until they were almost home that Peter realized he was still holding Hill's phone.
