The fragments came faster now, overlapping, layering.
Voices cut through the rush of time—fragments of a conversation Jude recognized even though he hadn't been there to hear it:
"How long until Firestorm reaches critical mass?"
"We don't have four hours. We need to stop his vital signs now."
"We just got Ronnie back to the lab this morning. We are not giving up on him."
"We are out of time—"
The scene flickered and shifted. The sealed room. Wells alone, the yellow speedster suit hanging beside him like a shed skin. He was working with careful hands, extracting a small component from the tachyon prototype on the suit's chest—the part that housed the faster-than-light particles themselves. His face was composed with the practiced neutrality of a man making a calculation he doesn't enjoy.
"Gideon—can the tachyons be transferred into the quantum splicer?"
"Tachyons are viable fission elements for the quantum splicer. However, converting the prototype will significantly delay your future plans."
A pause.
"If Central City is vaporized by a nuclear explosion, there won't be a future to plan for."
"Oh no."
Jude stared at the dissolving light-fragment, cold comprehension spreading through him.
It was me. It was my fault.
In the original timeline—the one that had existed before he arrived—Firestorm had not been handled early. Ronnie and Stein had remained unfound, the matrix destabilizing at its own pace, until the situation became critical enough that Wells had no choice but to sacrifice his tachyon prototype to fuel the quantum splicer and prevent Central City's destruction. That sacrifice had worked. It had also meant that Wells no longer had the faster-than-light particles needed to push his own speed to the threshold. The gap between that timeline and the one where Barry and the Reverse Flash could punch a wormhole in spacetime had been enormous—months, perhaps longer.
In this timeline, Jude had brought Firestorm in early. Stein and Ronnie had been separated cleanly, on schedule, without incident. The city was never in danger. Wells had never needed to sacrifice his tachyons. He'd kept them, used them, and accelerated his own speed far ahead of when it should have been possible.
The butterfly had flapped its wings in a food truck on a residential street, and somewhere downstream, the timeline had cracked open a decade early.
I thought I was keeping the disturbance minimal, Jude thought, watching the fragment dissolve into the current. Apparently, the universe and I have a different definition of 'minimal'.
He checked his connection to the timeline—the internal indicator he'd learned to read over months of careful navigation. The progress bar sat at 55%.
45% left. And at the rate things are accelerating, that might be a problem.
Time kept reversing.
The city streamed past him in the wormhole's current, and as it did, the histories changed. He could see both versions—the original and the one he'd created—flickering side by side like two prints of the same photograph developed in different darkrooms.
Clyde Mardon, raising a gun to the Detective neck and pulling the trigger. Mardon, dropping the same gun after a conversation that shouldn't have happened, and walking away.
Danton Black—Multiplex—losing his wife in litigation, going to Stagg Industries with nothing left to lose, falling from the building's upper floor. Danton Black winning the patent case instead, walking out of a courthouse with his wife, both of them planning what came next.
Stagg Industries, its founder convicted and imprisoned.
Bette Sans Souci, bleeding in cold seawater, General Eiling's bullet finding her before she could reach anyone who could help—her body destabilizing into a final, terrible explosion somewhere in the ocean. Bette, alive and relocated, surfacing in Gotham City under circumstances that had required a great deal of quiet coordination to arrange.
The original histories shook and dissolved. The new ones settled into place, fixed into this timeline's record, already old enough to have the solidity of fact.
Does the universe endorse what I've done? Jude watched the changes crystallize around him. Or is it simply that I carry some property that lets me exist at the intersection of timelines without the whole thing collapsing?
He didn't know. But looking at it—the people who had died in one version of events living full lives in this one—he felt something that wasn't quite satisfaction, but was adjacent to it.
At least it wasn't wasted.
He didn't have time to reflect on it. The current pulled him faster, the wormhole narrowing toward a point.
A red streak of lightning split the timestream—there and accelerating, moving backward through the decades with the deliberate momentum of something that knows exactly where it's going.
The Reverse Flash.
Behind it: a golden thread, pulling hard to close the gap.
Barry, in his red suit, in pursuit.
Jude watched the two of them race backward through thirty years in the space of a few seconds. He understood now, fully, what he was watching. The speedsters' battlefield has no edges—when they're fast enough, everywhere is the battlefield, and everywhen. A fight could begin in the present and end during the Mesozoic Era if the combatants had enough velocity.
These two had the velocity.
The red and gold lightning drove downward toward a night. A street. A house.
Jude followed, helpless to do otherwise.
He arrived at the edge of the scene the way a dreamer arrives in the middle of something already happening.
The living room was lit from the inside by the clash of the two speedsters—gold and red and the strange violet-white of disrupted air. Furniture exploded outward from the sheer pressure of their movement, walls cracking under forces they weren't built to withstand. In the center of it all, a small boy sat on the floor, eyes wide, watching two figures move so fast they were barely visible.
The Reverse Flash drove toward the child. The Flash caught him from behind.
A woman's voice echoed from the hallway—sharp with fear, not yet understanding what she was looking at.
Then a man, appearing in the doorway with her. Henry Allen. He saw his son on the floor surrounded by impossibility, and he did what a father does: he pushed through the chaos, grabbed the boy, and pulled him back.
The Reverse Flash broke toward Henry to stop the rescue. The Flash intercepted him—a single punch that sent the yellow figure staggering—and Henry got young Barry out.
But Nora came in behind him.
She had no context for what she was seeing. She didn't understand the two streaks of light circling her, each one fighting to reach the other, each one using the space she occupied as the battlefield's center. The wind from their movement tore through the room. She screamed. Henry and young Barry screamed back from the doorway.
"Run! Barry, run!" Henry grabbed his son by the shoulders and pushed him toward the front door, his voice cracking. "Go—I'll get your mother, go—"
The side door of the room opened a crack.
Another Barry stood behind it. The Barry from Jude's present. In the red suit, still half-breathless from the chase through time. He had one hand on the doorframe and was clearly calculating whether to break through into the room—whether there was still time, still something that could be changed.
The older, future Flash—the one locked in combat—caught his eye through the chaos.
The future Flash stared back at his younger self in the doorway.
And then he shook his head.
Don't.
The child crying in the hallway didn't understand it. But the Barry in the doorway did. He understood it instantly, which was why his acceptance of that head-shake was immediate and certain rather than agonized. This moment was fixed. What was happening in this room was already part of the architecture that had made him who he was. Changing it would unmake too many things. He had come back to stop the Reverse Flash from killing the child. The child had been saved. That was the mission.
The rest—
The present Barry withdrew behind the door, closing his eyes.
Inside the room, the future Flash and the Reverse Flash were still locked together—but the Flash was already ahead of the objective, moving to extract young Barry from the street before the Reverse Flash could reach him again. Once the boy was miles away, the Reverse Flash's tactical advantage dissolved. He didn't pursue.
Instead, he stopped.
And his glowing red gaze moved, slowly and with terrible deliberateness, to Nora Allen—still standing in the center of the ruined room, still not understanding, her face wet with tears she didn't know she was crying.
