Image Credit: ABCTwo weeks ago, we descended down a scary ladder and entered a cave. Last week, we trekked through the jungle and climbed up a lighthouse. So, what kind of Outward Bound field trip will we be taking in this week’s episode of Lost? Your guess is as good as mine. (Unless you guessed a snow-shoe expedition leading to a pile of polar bear droppings. Then yours is worse.) But before you embark on tonight’s adventure, “Sundown,” treat yourself to the latest installment of Totally Lost, in which two of EW’s tallest staffers—Jeff Jensen and Dan Snierson—engage in a freewheeling discussion about “Lighthouse,” covering everything from Jack’s surprise son to Claire’s squirrel baby. In addition, you’ll hear directly from Emilie de Ravin and receive a few teasers for “Sundown.” So press play and then use the space below in a creative manner. Tell us: Who is Jacob trying to bring to the Island? What does the name Wallace mean to you? And on a scale of 1 to 10, how scared of Claire are you right now? (Feel free to continue your journey into madness by visiting our Lost hub and following us on Twitter @ewdocjensen and @dansnierson.)
