This is it, folks: This is absolutely the very last episode… before the series finale. And before you get all nostalgic, watch the video and then type your feelings below: What did you make of “Across the Sea”? Do you buy into the idea that Mother may have Smoke Monster-y abilities? And if you had to give the Man in Black a name, what would it be? (Hit @dansnierson with your inspiration, and the best answer that’s not Nigel will receive its due in a manner to be determined later. How’s that for a sexy prize?)Last week, Lost gave us a different kind of episode, one in which we journeyed back to the earlier days of the Island, where we met the Boy in Black, Jacob as Junior, and one crazy Mother. This week on Totally Lost – the Lost web show that is 47 percent Doc Jensen, 44 percent Dan Snierson, and 9 percent “Other/No Response” – we break form to delve into the mysteries of “Across the Sea.” You may find the experience therapeutic. You may also find it a little bizzare. In any case, we hope to shed light on the episode with the help of some very gracious – and hilarious – guests. We’ll also be changing up the teasers this week for the ominously titled “What They Died For.” Sorry, but you don’t get three hints about tonight’s action – you get four!
