Long-Lost Relative

A long-lost relative is the reunion genre's centrepiece: siblings separated by adoption matching on a DNA site, cousins colliding in comment sections, the coworker who turns out to share a grandfather. Databases made the finding easy; the strangeness moved into the coincidences around it — pairs who had already met, lived streets apart, attended the same wedding. Filed accounts here often need no verdict on truth, only on odds, and the jury argues probability like actuaries with goosebumps.
