# new 02/06 - A decent Juliet fix awaits you tomorrow night. Not only is there a nice little scene with her and Sayid on the beach, but she ends up saving the day - much to Kate's chagrin. Speaking of which, there's a Kate/Jack/Juliet moment that will have you peeing your pantaloons. It's that funny. It's also pretty subtle, so your full attention will be required.

# 01/23 - But the biggest mystery hanging over Lost's fourth season, beyond who makes it off the island, is how rescue-friendly those freighter folk will turn out to be. Could the quirky quartet -- Fahey, Davis, Rebecca Mader, Ken Leung -- win up making Others leader Ben look downright cuddly? Expect the February 7 episode to shed light on the gang's true mission.

# 09/12 - Lost was filming along a small streambed at Judd Trail, up Old Nuuanu Pali Road. A perfectly Lost-y jungle location. All the action was out of sight, but it was good to see some familiar faces on the crew. I can only tell you that there was a major confrontation (I could hear yelling echo through the forest), and can rattle of the list of actors I spotted. But I think you'll agree, this simple list alone is enough to get one's heart aflutter. This was a major shoot! Jorge Garcia (who was kind enough to stop and chat), Terry O'Quinn, Mira Furlan (in a nice checkerboard flannel-type shirt), Josh Holloway (who I believe was the aggressor), Michael Emerson (who appeared to have been on the losing end of a fight), Blake Bashoff and Emilie DeRavin. Of course there was at least one baby being carried around. Names overheard but not seen include Evangeline Lilly, "Carla," "Alex," "Karl," and "Fuzzy" (likely stunt pro Robert Moody). During my brief chat with Jorge, he again expressed a great deal of excitement and anticipation for the first few scripts of Season 4, comparing it to Season 1 in richness and mind-blowing moments. He also recalled meeting friends of mine yesterday at the "Santa Rosa" location, summarizing the shoot with a long, delicious, "Whew!" I think it's safe to say fans are no less excited about the return of Lost. My friend Darcy also visited the location later in the day and saw Matthew Fox in a scene with Evangeline and Jeremy Davies. Davies, playing a character named Daniel, was wearing a vest with a blinking light and made a call to someone named George, presumably or supposedly on Naomi's ship. Source: The Transmission
# 09/12 - Jack, Kate and Daniel are hiking uphill through the jungle. When they reach the top of a rise, Jack and Kate sit down to rest while Daniel, who's wearing a black vest with a flashing red light (probably identical to the one Naomi has on when she parachutes down to the island) pulls out some sort of communication device (again, possibly the same as Naomi's "phone") and says something like: "George, it's Daniel. Yeah, my instrumentation went crazy. Seemed like some kind of electrical storm. I'm here with some of the survivors." The rest of the dialog was inaudible, but Daniel and Jack seemed to be saying a lot to each other. The take was rather long, perhaps a full two minutes. Source: Lost Spoilers

Not-Penny's-Boat People

This is a flashback episode featuring the freighter people

So it's like an "Other 48 Days" type deal? I hope it actually advances the island story too instead of just providing background info on them -- "The Other 48 Days", if you'll recall, was packed full of info but ultimately ended up at the same point as the episode before it -- if only for the sole reason of not having to put up with the insufferable comments on this board should that be the case.

It seems to me that Jack, Kate, Hurley, etc.. made a choice to leave the island folks behind. I'm really waiting to see if it comes to a point where there's an ultimatum that only 6 can leave and communicate to the rest of the world that they were the sole survivors. Based on Charlie's reappearance, it certainly doesn't seem like the remaining survivors are doing well on the island.
