Peter's Spidey Sense buzzed much louder. Peter tore his eyes away from where Quill had disappeared. His eyes landed on Tony as he stared at his hands in horror.

"Mr. Stark?" Peter took a step toward Tony. Tony fell forward, and Peter caught him. He slowly laid Tony on the ground. Tony grasped Peter's hand.

"Peter, you're going to be okay. You hear me?" Tony looked Peter in the eyes. "You are going to get through this."

"No, Mr. Stark, don't leave me!" Peter sobbed, his tears falling onto Tony's jacket as he slowly turned to dust.

Tony smiled at him faintly. "You'll get through this. You're my son, Peter." Tony's head slumped, and he dissolved into ashes.

Peter's hand fell through the space where Tony's chest had been. "No!"

"Peter."

He turned to where Doctor Strange was sitting. "There was no other way." Strange dissolved into ashes.

Peter slid onto the ground beneath him. His body shook as he wept. In front of him, the blue alien, Nebula, lowered her gaze. "He did it."
