"Black Lightning?"
The other Barry turned the name over like he was looking for a familiar shape in it. "I've never heard that name in my universe. Is he one of your enemies? Some kind of meta?"
"Not a person," this Barry said. "Not exactly — I'm not even sure it's alive, in any meaningful sense of the word." He paused, searching for the right frame. "You don't have them in your universe? They move through the Speed Force. Use the Speed Force. If a speedster gets caught by one, they die — instantly, cleanly. They look a bit like something out of a zombie movie, except without any of the sluggishness. Their speed is—" He shook his head. "Ridiculous. I still don't fully understand what they are."
"Oh." The other Barry's expression cleared. "You mean Time Wraiths."
"That's what you call them?"
"In my universe, yeah." He tilted his head. "Black Lightning doesn't quite fit. They're more like..." He considered. "Temporal undead. Reapers for people who break the rules of time."
Jude had gone quiet.
He was running his own internal audit, and the numbers weren't quite adding up. Based on everything he understood about where this universe sat in DC's long, chaotic publication history, Black Lightning — the Speed Force predator — should still be a fairly rudimentary concept here. The early framing: a threat that emerged only when a speedster was already at death's door, not a proactive timeline enforcement mechanism. That was a later addition. A patch.
So why did this universe's version already carry the timeline-policing implications that belonged to a much later era of continuity?
Because of me, Jude thought. Probably. Almost certainly.
He filed it away before either Barry could notice him staring at the middle distance.
"The name doesn't matter," this Barry continued, drawing them both back on track. "What matters is: reckless interference with the timeline might bring them. However we got Nora here, however technically clean the method was — are you certain it's safe? That nothing noticed?"
Both of them looked at Jude.
"Without me involved, I couldn't say," Jude answered. "The method is sophisticated — the body substitution means the timeline sees what it needs to see. But nobody has a complete map of how the Wraiths decide what constitutes a violation. The safest answer is that I handle it, because I already did."
"And that keeps them off you because...?"
"I'm a special case." Jude kept his voice neutral. "Timeline changes don't affect me. And I'm not a speedster, so they have no jurisdiction."
Both Barries stared at him with the same expression — which was, in itself, slightly unsettling.
"A person the timeline just... ignores." This Barry clicked his tongue slowly. "I've never encountered anything like that. Not even speedsters can claim that — we can move through time but we're still subject to it. We still leave marks." He looked at Jude with something that was half admiration and half the particular wariness reserved for things you don't fully understand. "How does that even work?"
How does it work, Jude thought. Good question.
The system had actually explained it, once. He'd been on his way back from the other universe when the notifications had surfaced — presumably triggered by the fact that he'd just been dragged through a time-space transit by a pair of speedsters, which had apparently been enough of an edge case to prompt the relevant documentation.
SYSTEM NOTICE:As an external reader, your timeline runs parallel to this world's timeline — but does not fully overlap with it.
SYSTEM NOTICE:The world you inhabit follows the Reader's timeline. Setting additions introduced after initial deployment are not applied retroactively. They take effect going forward. As a result, multiple versions of the same world exist simultaneously within the Reader's timeline: versions without the subsequent additions, and versions with them.
SYSTEM NOTICE:Changes to any world's timeline will not affect your actions or position, as you do not exist on any world's timeline.
It was the second time the system had gone into this level of detail about what he actually was, and like the first time, reading it produced the quietly pleasant sensation of finding a banknote in the pocket of a jacket you hadn't worn in three years.
The short version, as best he could reconstruct it: the DC universe had not been built — it had been accumulated. Hundreds of writers, hundreds of editors, decades of stories that contradicted each other, ignored each other, retroactively rewrote each other, and occasionally produced something so incompatible with prior continuity that the only solution was to declare an entirely new universe and start over. Every time someone introduced a new element — a secret organisation that had always been there, a cosmic threat that had always been lurking — the setting shifted. The patch was applied. And from inside the universe, nobody could see the seam.
Gotham was the canonical example.
In the beginning: a corrupt city with a crime problem and a detective in a bat costume trying to fix it. Clean enough. Comprehensible.
Then the stories accumulated. Batman got smarter, faster, more capable. He could outthink assassins and alien invasions and gods. He could go toe-to-toe with Superman. He could plan for every contingency in the known universe.
And he still couldn't solve the gang problem.
Which was — objectively — not coherent. So the patches arrived. Gotham acquired layers: an ancient curse, a secret organisation that had been manipulating the city since before Bruce Wayne was born, evil embedded in the bedrock, supernatural forces woven into the architecture. Now it made sense. Of course Batman couldn't fix it. Nobody could fix a city that was metaphysically broken.
But from inside the universe, everyone simply believed the organisation had always existed. They couldn't find the version of Gotham that predated the patch — because the patch had been written into the beginning.
From outside, though — from the perspective of a reader watching each issue arrive in sequence — both versions existed. The pre-patch Gotham and the post-patch Gotham, occupying the same coordinates in different layers of the same timeline. A reader could see both.
Which meant a reader could, in principle, touch both.
Jude turned this over in his mind with the particular discomfort of a man who had just realised that a word he'd been using casually for years had a much larger definition than he'd assumed.
High-dimensional being, the logic ran. That's what you are, technically.
He looked down at his hands. Regular hands. Slightly calloused from cart work. Perpetually underpaid.
High-dimensional being with the personal power of a moderately fit civilian and approximately four hundred dollars in savings. He supposed the universe contained multitudes.
He surfaced from the thought to find that the two Barries had, while he wasn't paying attention, reached a conclusion.
"You and Henry take her back to Central City," the other Barry was saying. He'd had the shine of emotion behind his eyes for the last several minutes, and he was managing it with the practiced efficiency of someone who had learned a long time ago to keep functioning while feeling things. "Give her some time to settle in, let the world feel familiar again — and then I'll explain everything. In person. All at once, properly." He paused. "The shock will be less if she's already comfortable."
This Barry nodded slowly. Jude nodded too.
It was a good plan. Straightforward, graduated, humane. The kind of plan that had a reasonable chance of actually working.
Which was already an improvement on how the morning had started.
