Endgame

Once upon a time, the universe went quiet.

Not the good kind of quiet. The empty kind. The kind that comes when half of everything that was supposed to be there is suddenly not. Half the voices. Half the footsteps. Half the lights in half the windows of a trillion worlds.

Thanos had snapped his fingers. Five years ago.

Rocket was still there. He had been one of the ones left behind, and he had gone to Earth and worked alongside the Avengers: Natasha Romanoff, who was capable and never let anything go; Steve Rogers, who was steady as stone; and Nebula, who was Gamora's sister and one of the toughest beings Rocket had ever met. They kept working. They kept trying to help where they could. None of them said out loud what all of them felt: they were waiting for something to change.

The change came in the form of Scott Lang, who arrived at the compound slightly bewildered and full of a theory. Scott was a person who could shrink to the size of an ant or grow to the size of a building, and he had recently spent what felt to him like five hours in the Quantum Realm — the strange between-place where time moved at different speeds, where minutes and years did not apply the way they did everywhere else. Five hours inside had been five years outside.

What if, he said, you could use the Quantum Realm to travel in time? Back to specific moments — retrieve the Infinity Stones before Thanos had ever collected them, bring them back to now?

The room was quiet.

Rocket's eyes went sharp and bright.

Tony Stark proved the equation — solved the theoretical problem nobody else could crack. But the equipment that made the theory real was entirely Rocket's. Quantum tunnel emitters with tolerances no commercial hardware could achieve. Pym Particle dispensers, precisely calibrated for each person, for the size-shifting the Quantum Realm required. A relay system that kept every Avenger's time coordinates synchronized across different points in history. He built it in four days, sleeping barely at all, eating when Natasha put food in front of him and being short about it. When every system registered green, he sat back and thought: good.

The Time Heist.

The Avengers scattered across history. Rocket went with Thor to Asgard in the year 2013, while the Dark Elves were attacking the golden city and the Reality Stone — temporarily carried in a human called Jane Foster — was loose enough to retrieve.

Thor was a complication. His mother Frigga was alive in this year, and he had been carrying her loss for a long time. He stood outside her chambers unable to walk away. Frigga, who was perceptive in the way of someone who loves someone well, came out to find him. She understood more than she should have — saw her son older in a way she couldn't name, carrying something heavy from a future she would never see — and she spoke to him with steady warmth.

"You're here," she said. "That's enough."

Rocket watched from around the corner, impatient and uncomfortable and not entirely sure what he was feeling. He had not had a mother. He had had a laboratory. But he had stood beside Groot growing back from a twig, leaf by leaf, talking quietly to a pot in the dark — and that had been its own kind of this.

They retrieved the Reality Stone and returned.

Back in the present, the Avengers assembled their collected Stones. Tony Stark built the Nano Gauntlet. The Hulk wore it and snapped. The universe came back — not with thunder, but with the soft sound of presence returning. Footsteps. Voices. People blinking back into existence on fields and streets and ships across the cosmos. Half of everything given back.

Rocket exhaled.

Then Thanos came from the past with an army, and the battle that followed was the largest of Rocket's life. Every hero. Every ally. All of them on that broken field together. Rocket flew and fought and kept moving.

Tony Stark caught the Stones and snapped one final time. Thanos's army dissolved.

The field went quiet. Tony Stark lay still, the price of holding all six paid in full. Rocket stood back, feeling the shape of a victory that was also a loss.

Then he looked across the field for Groot.

Groot was there. Tall, alive, standing in afternoon light, the soft glow he made when calm flickering at the tips of his branches.

"I am Groot," he said.

Rocket walked over and stood beside him and said nothing at all. They stood together in the light of a world that had come back, on a day that had almost not ended this way.

Once upon a time, the universe went quiet. But this story did not end there.
