Reality Subtext: Sable would always flip out in matches if her opponents went after her face. She had strict regulations on how many bumps she could take (no front bumps at all, nothing that might damage her face) and for her match at WrestleMania 14 her opponents were warned not to disfigure her in any way (she had a Playboy shoot coming up).
Romance on the Set: Twice. First with real life husband Marc Mero which was onscreen as well. Secondly with Brock Lesnar of all people. Though, it does tell us something about her taste in men, since Mero was a boxer-turned-wrestler and Lesnar is a wrestler-turned-Mixed Martial Artist-turned-wrestler again. She is clearly drawn towards men who can fight.
Screwed by the Network: Invoked this when she left WWF, claiming sexual harassment among other things. Her claims were disputed in court by various WWF executives. She won the rights to money made from Sable merchandise, but she didn't get the rights to the Sable gimmick or get her no-compete contract clause revoked so she could work for WCW.
The angle with Tori was originally going to have her turn out to be Sable's sister. They went with the obsessed fan story instead.
WWF wanted to give Goldust's valet Marlena an ambiguously lesbian gimmick to match Goldust's Gorgeous George gimmick, and wanted Sable to be the other half of it, but Sable refused.
After leaving WWF, Sable was supposed to head to WCW, where she was planned to be the driver of the white hummer that hit Kevin Nash's limo. But since she had a no-compete clause in her WWF contract, she wasn't allowed to work for WCW in any capacity.
