• The event started off with a clip with Michael Emerson (Ben) referring to the Others a "Rebel Sect"
• A Voice-over in the same clip then revealed: "The survival of the Island is now at stake."
• Carlton says Rachel probably won't be on the Island.
• Damon says the benefits of only doing 16 episodes (versus 22) a year is they can do more ancillary "awesome" stuff.
• Damon and Carlton say don't get too attached to Richard Alpert, because the actor that plays him, Nestor Carbonell, is staring on a new CBS series called Cane.
• Cuse said that flashbacks and flashforwards will both be part of the upcoming season.  They were running out of plausible flashback material, so it was time to switch gears into flashfowards. The end date allowed them the certainty necessary to add that element into the show without further antagonizing fans. Carlton: "What you saw with Kate and Jack was not the end of the show." Damon: "The show has never really been about getting off the Island...There's this whole chapter of the story that takes place off the Island."
• Lindelof nodeed furiously when asked if Jack and Claire would find out they are related.
• When asked two questions of Did Ben get caught by Rousseau on purpose and Did Ben kill the real Henry Gale?  Carlton answers: "He got caught by accident." and Damon volunteers this, regarding Ben vs. Henry Gale: "They had words."
• The duo revealed that Harold Perrineau is indeed returning as Michael Dawson but they don't want to reveal how or when he returns; however, Damon Lindelof claimed that he would return ealy in the fourth season. Carlton, regarding poor crazy Michael, "He took some extreme actions." Michael's story is about the power of the Island to be redemptive. And this won't be a quick pop by Redemption Island; Harold is a series regular.
• The question was asked, Will we get back to Libby and was she part of Dharma?
  Carlton answered: "It is our intention to get to Libby's story this year, and we think you will be happy when we finish that." Damon added: "You're not barking up the wrong tree."
• When asked if there will be a Danielle flashback soon Damon responded, "There are important things going on in that story, and they have to sync up." They'll do that syncing in this season or next.
• We are told by the pair that the answers to the Monster WILL be answered this season.  Carlton: The monster answer is "not going to be 10 seconds of blank tape." They also confirmed that the C.V. on the blast door map referred to Cerberus Vent, and therefore Dharma at least, referred to the monster as Cerberus.
• The promised clip is one of the station orientation films, hosted by Marvin Candle under an alias. The footage begins with him getting his makeup done and smoothing down his Dharma labcoat. Bunnies! It's about bunnies! Bunny #15, to be specific. Marvin, who calls himself Dr. Edgar Halifax in this film, identifies it as station six, the Orchid. He says the viewer has probably realized by now that he or she is not working at a mere botanical research unit. He apologizes for making him or her lie to friends and family members about the nature of the work. He mentions something that sounds like "Kasimir effect" and mentions the "unique properties of the Island." Then there's one of Jacob's subliminal messages. It may have been some variation on "as Jacob loves you." Then there's a bunny riot. One of the station's alarms blares, Dr. Halifax/Marvin panics. There's an intercut clip of someone riding a bicycle. The clip is inserted upside-down, and the rider appears to be in the village green of Otherville...And then, amid the chaos (perhaps this is the Incident?), the filmstrip slides off the reel.
