After Yunjin Kim introduces this installment of Totally Lost with a bit of mystery, we get Lost in translation, discussing everything from surprise Sideways guests to Sun’s language barrier to why Widmore transported Desmond to the Island. We also offer teasers for tonight’s episode of Lost, “Happily Ever After,” and an analysis of a certain promo strategy. (Note: Turns out that the great Stephen Colbert already beat us to the punch, but what can we say? If we can’t be as timely, let’s at least be not as funny.) After you watch, tell us below: Where do you think the Sideways story is going? Which blast from the past would you most like to see in the Sideways world? What did you make of Sun’s aphasia? And how does Desmond fit into Widmore’s plan?

(P.S.: If you have any trouble viewing videos in PopWatch or if you’re on an iPhone/iPad, head over to the Totally Lost hub to see Part 1, Part 2, and Part 3. For more diversion, follow @ewdocjensen@dansnierson, and our magic-making producer/editor/spiritual counselor @ewjasonaverett.)
