And Continuing the Self-Indulgent Lost Thread

From Entertainment Weekly‘s ComicCon coverage:

Though loath to reveal any more details about season 4, [Carlton Cuse and Damon Lindelof] did tip off fans to a few, often cryptic, coming attractions. Jack and Claire will likely figure out that they’re brother and sister. We’ll find out why Ben came to the survivors’ side of the island in the first place. The Kate/Jack “flash-forward” in the last episode last season does not take place at the end of the series. Libby, who’s backstory will be explained this season, may have been a Dharma employee. And remember those mobisodes? They’ll hopefully, finally launch in the fall. The pair also tipped Con-goers off to a few questions fans should be asking: “Who’s in the coffin?” and “Who’s on the freighter, and what do they want?” Then just when you thought you couldn’t get more confused, the duo unveiled another choppy Dharma Initiative reel, which you can see by going to ABC.com today at 5.

UPDATE: Here’s a link to the Dharma video.
