Local stuntman Darin Fujimori has confirmed the Bai Ling story from earlier. Fujimori just finished shooting an episode of "Lost." And this time, he was the one delivering the beating.
The episode, featuring an appearance by Bai Ling, includes a flashback from Jack (Matthew Fox), set in Thailand. Fujimori plays Ling's character's brother and, as brothers are sometimes wont to do, he and his on-screen buddies put a beat-down on his sister's would-be suitor, Jack. Source: Honolulu Advertiser
