Please don't read any further if you haven't seen LOST yet; there may be questions I pose that spoil the episode for you. If you don't care, read on!
Nobody likes Ben. Why do they want him?? Who does he have on the boat? What kind of information does he have that could be helpful or useful for these people? What is the original pilot of 815 doing piloting a chopper back to the island? What are a physicist, "soil sample analyst" or medium of sorts, pilot, and anthropologist doing together? Not to mention that it sounds like the beginning of a joke.
On the other hand, I'm glad they answered the question of why they're on the island - to get Ben. But why? Questions, questions, questions. Looking forward to next week!
