Dr. Elliot Vance is two miles underground in the Creighton Nickel Mine, alone, on month seven of a twelve-month rotation. His lab is the most shielded environment on Earth. Ten thousand tons of ultra-pure heavy water around him, two miles of Canadian bedrock above him, and a four-terabyte hard drive full of Seinfeld to keep him sane.
This morning, his daily data packet from the surface arrived with one tiny inconsistency. Forrest Gump says was instead of is.
He runs the audio analysis. The waveforms do not match.
He checks the fine-structure constant. It has shifted by a fraction of a decimal point.
The universe rewrote itself overnight. Every brain on Earth got the patch. He did not, because the shielding held.
He is the last person on Earth who remembers.
In 94 hours, the new timeline will eat through his tank and erase him along with everyone else. He has four days, a Nintendo 64, and a 7,541-piece Millennium Falcon LEGO set he is about to dismantle for parts.
