Kade leaned back and closed his eyes to work. He’d spent the last week offline, in areas with no net access. Now they were approaching civilization again. He reached out to the phone networks, and from there through a cloud of anonymization servers to the broader net. Nexus traffic flashed around the world, now, disguised as other sorts entirely. In the vast data flows of machines talking to machines, it was a bare trickle of bits, easy to hide.

Information streamed into his mind. Software collated it, organized it.

First he surveyed the reports from the agents he’d sent searching for Rangan and Ilya. Small autonomous pieces of code, they used the backdoors he and Rangan had installed in Nexus – with the new passcodes Kade had set just hours before he’d released Nexus 5 – to search the minds of Nexus users, hunting, always hunting…

Ilya would hate this, some voice inside himself whispered. I’m invading privacy on a massive level.

Kade ignored it. He’d started down this path to find her. Her and Rangan.

It wasn’t easy to write a bot that would sift someone’s mind for knowledge of two individuals. What to key off of? Their names? Their faces? And if someone had heard one of their names? Had seen one of their faces in the news?

He’d had to endlessly fine-tune the variables. The face or name of either of them – spoken or read – in conjunction with a sense of captivity or imprisonment or prosecution or law enforcement. The person he was looking for would be an ERD employee, perhaps, or part of the wider Department of Homeland Security, or a contractor, or their spouse or lover or confidant. Someone who knew where Rangan and Ilya were, who would help Kade find a way to free them.

Over the last six months he’d gone through hundreds of false hits. Today there were dozens more, the consequence of his time in the wilderness between Cambodia and Vietnam. One by one he replayed the memories and discarded them. False positives, every one.

When he was done, he moved to the next category, the code updates. He’d pulled down hundreds from the most popular Nexus hub, the place where programmers and neuroscientists and others gathered to chat about, analyze, debug, and improve the Nexus OS that he and Rangan and Ilya had built.

Nexus OS was open source now. Anyone could change it. And hundreds did. The updates came thick and fast. Bug and crashes fixed. Security holes closed. New ways to share data, to write apps. Performance speedups. And deep neuroscience tools for working with memory, attention, emotions, sleep, and more, all the way down to raw neutotransmitter levels.

So much more than we could ever have done on our own, Kade thought. Hundreds of people hacking on Nexus now. Lots of them smarter than I am. The progress is amazing.
