Rebecca Bryant (née Garner) was an incidental character who first appeared in The Fisher King, Part 1.
Rebecca was born on July 15, 1988, in Las Vegas. She lost most of her family in an house fire that occurred on the night of October 12, 1992, caused by faulty wiring. Her father, future budding serial killer Randall Garner, saved her and suffered severe burns when trying to save the others. Rebecca was found crying in her backyard, apparently unharmed. Her father spent nearly three years in a burn ICU and decided to give up parental rights on Rebecca during his time in the hospital. She was first taken in by Joseph and Celia Bryant as a foster child before being formally adopted by them on December 4, 1993 in Clark County, Nevada. Upon maturing, Rebecca acted out severely, running away five or six times, doing drugs and committing vandalism, theft and truancy. When she was abducted from South Boston, Virginia on February 25, 2004, by a now-delusional Randall, nobody bothered to make a full search because of her rap sheet. She was held captive in a tiny room in his basement, chained, for over two years.
