Looks like Kristin has some decent info this week about 2 new characters for Episode 8
Bonnie in Stillwater, Florida: Anything on Lost? Episode eight, the last script completed before the strike, shoots today through the Tuesday after Thanksgiving, and then that's all Damelton wrote. Episode eight includes two new characters: Gus is an "inner-city, unruly character type. He's a sketchy business owner who preys on human weaknesses. Happy to exploit any opportunity he sees," and Noreen is "Very tough on the outside, nurturing on the inside. Confronted with something from her past, she defends herself well, despite the emotional toll."
