I adore the foreseeing storyline and another Desmond episode this season. Yey. What more to wish. And this one looks quite dark and not happy ending - for Charlie. And Desmond has decision to make - follow what he saw and let Charlie die in hope to find Petty or save his friend. And that is what it means to live with knowing what will happen and be afraid that your actions will change things.
Super episode. All that tracking, filling the visions, and the flashbacks. More facts about Desmond life. I adore the new character flashbacks as they are fresh and there is always something new and informing - some of the older character's flashbacks seems to get nothing new.
