Late, one night, he climbed to the rooftop and waited. The drone approached like a moth that had learned how to aim itself at the exact filament of light that made Tristan’s chest ache. It hovered there and projected, onto the low wall beside him, a short film: his mother teaching him to tie a knot, the way rain had once sounded on a tin roof where he’d lived as a child, the flash of his own laughter discovering a new corner in the world. Tristan felt each scene like a small theft and a small mercy. He did not know whether the drone had learned his memories from a feed or had glimpsed them in the thousands of micro-interactions it had witnessed across the city, but that didn't matter. For a long minute, he let the interruption break him open and stitch him back together.
