This episode brought up a ton of new theories and mysteries!
• What really happened when "the sky turned purple" as Mr. Friendly (Tom) says? Why is it preventing everyone from getting off the island?
• What's Juliet's and Ben's "history"?
• Is Mittelos an anagram for "lost time"? Is the island some sort of time anomaly?
• Was Jacob's name in the brainwashing film a clue referring to Jacob, the true leader of the island?
• Were the Others recruited to be on the island the way Juliet was?
• What's the deal with Karl... and the brainwashing film... and the weird drum-and-bass/rave music?
