The document opened with the crispness of a classified military blueprint. The cover page showed a grayscale illustration of a machine—sleek, brutalist, the size of a small refrigerator. It had a slit-scan lens array on the front and a bank of unmarked toggle switches. Above it, in bold serif font:
<REINTEGRATION PROTOCOL FAILED. SYNCHRONIZATION REVERSED. OPERATOR A, YOU ARE NOW OPERATOR B. CHECK YOUR PULSE.>
He double-clicked.
And then—just for a second—Leo felt another hand typing on his keyboard. The keys didn’t move. But he felt them: cold, metal, belonging to someone who hadn’t been alive since 1993.
He didn’t remember getting it.

See Appendix D: Reintegration Therapy. Leo stopped. He was no longer skeptical. He was unnerved.
