Thanks to Bob for the heads up on the new Kristin spoilers.
Jamie in Mobile, Alabama: Are Claire and Jack siblings on Lost? Big spoiler alert. Yes, they are. And we'll know it before they do.
From George in Tallahassee, Florida: Who is the new female regular on Lost? I'm pretty sure she's a subterranean character. Damon and Carlton seemed to admit there's a whole underground contingency on the island in the latest Lost Redux video clip.
