Her first encounter with the gargoyles took place during Goliath and Lexington's first battle with the Pack. Her husband shrugged it off as a publicity stunt, but Sarah was still visibly frightened at what she saw ("The Thrill of the Hunt").
In the script for "The Thrill of the Hunt", Sarah was referred to as "Billy's Mom". Greg Weisman has since revealed her name as Sarah Browne. She kept her maiden name.
