Chapter 4: The Station

The research station looked like something assembled from leftover parts of other projects. Shipping containers welded together, solar panels at angles that suggested function over aesthetics, and a satellite dish pointed at a section of sky that looked no different from any other section.

Sarah had been walking for ninety minutes. Her Rothys had given her two blisters—one on each heel, symmetric—and her face felt like she'd been standing too close to a campfire designed by someone who hated her.

A woman was standing outside the station entrance. She was wearing cargo pants, a tank top, and Sarah's exact face.

"You made good time," the woman said. "I was expecting another twenty minutes."

Sarah stopped walking. Seeing yourself was one thing in concept. Seeing yourself in reality was like discovering your reflection had continued living without you.

"You look older," Sarah said.

"Eighteen months of desert living will do that. Also I'm growing out my bangs, which was a mistake." The other Sarah gestured at her forehead where hair was attempting to become something. "Come inside. You're dehydrated and probably in shock."

The interior of the station was surprisingly cool. Air conditioning hummed from units that looked homemade. The main room was filled with equipment that Sarah recognized from her brief stint dating an astrophysics grad student—monitors, servers, cables connecting things to other things in ways that suggested someone understood the topology.

Two other people were in the room. A man in his sixties with Albert Einstein hair and the kind of glasses that meant he'd given up on vanity, and a younger woman with half her head shaved and the other half dyed the color of a warning sign.

"This is Dr. Reeves," the other Sarah said, pointing to Einstein hair. "And Kayla. They're the ones who broke the timeline."

"We didn't break it," Dr. Reeves said. "We just revealed that it was already susceptible to breaking. There's a difference."

"Cool distinction," Sarah said. "Very comforting."

Kayla handed her a bottle of actual cold water and a protein bar that tasted like chocolate-flavored cardness. Sarah ate it in four bites.

"So," Sarah said. "Timeline splits. Quantum computing. Corporate murder. Someone want to explain how these things connect?"

Dr. Reeves pulled up a monitor showing what looked like a very complicated tree diagram with too many branches. "Three months ago, we achieved quantum coherence at a scale previously thought impossible. We created a processing system that exists in multiple states simultaneously. The problem is, those states started manifesting physically."

"In English."

"We made a computer that accidentally made new versions of reality," Kayla said. "Every time it solves a problem, it creates a timeline where each possible solution is correct. Normally this would collapse back to one timeline. But our system is so powerful it's stabilizing the splits."

The other Sarah—Sarah-2, Sarah's brain decided to call her—pulled up another screen. "Your company has a data contract with this facility. They've been using the quantum system to optimize logistics. What they don't know is that every optimization creates a version of reality where that solution succeeds. Including solutions where certain employees become liabilities that need to be removed."

"So the computer decided to kill me?"

"The computer suggested it. Some mid-level VP made it policy. By the time Marcus forwarded you that meeting invite, it had already happened in three other timelines."

Sarah sat down in a chair that might have been stolen from an office park. "How many versions of me are out there?"

"That we know of? Seven. Three died on the highway. Two made it to different research stations and are helping with containment. One joined a commune in Arizona and refuses to engage with the quantum stuff. And you."

Existential Redundancy: The feeling when you realize you're not just replaceable but already replaced.

"What happens if we don't fix this?"

Dr. Reeves pulled up a projection that looked like a tree exploding into fractal geometry. "The splits continue. Every decision point creates new branches. Within six months, there are potentially thousands of you, all slightly different, all existing simultaneously. The quantum system can't sustain that level of manifestation. Reality collapses."

"Reality collapses."

"Probably just local reality. California, Nevada, parts of Arizona. Might be containable."

"Might be."

Kayla offered Sarah-2 a look that contained entire conversations. "We have a plan. It requires shutting down the quantum system in all timelines simultaneously. That means coordinating with all the Sarahs who made it this far."

"Why me? Why not just handle it with the Sarahs you already have?"

Sarah-2 was quiet for a moment. "Because you're the first one who walked east without hesitation. The others needed convincing. Took hours. You took ninety minutes. That means something."

"It means I'm gullible."

"It means you're adaptive. Which is what we need."

Sarah looked at the monitors, at the impossible tree of timelines branching into chaos, at her own face looking back at her from eighteen months in a subjective future.

"What do I have to do?"

Dr. Reeves pointed to a door at the back of the room. "There's a quantum terminal. You'll interface with it. The system will sync you with your other selves. It's going to feel extremely weird."

"Weird how?"

"Imagine remembering things you didn't experience but technically you did, in timelines where different choices led to different deaths. That kind of weird."

"Great. Love that."

Sarah-2 put a hand on her shoulder. "I know this is insane. I know you left San Francisco this morning thinking your biggest problem was a pitch meeting. But right now, you're the only version of yourself in position to stop this. The other Sarahs are waiting. We just need you to connect."

Sarah stood up. Walked to the door. Put her hand on the handle.

Behind her, Kayla said, "For what it's worth, you're handling this better than I did. I cried for like an hour."

"I'll cry later," Sarah said. "After I save reality."

She opened the door.
