Lost Season 3 Begins

That episode leaves a lot to think about:
1. Ben (Henry Gale) and Juliet were at one time an item?
2. Why is Stephen King's Carrie Juliet's favorite book?
3. Where exactly on the island do the Others live? The island looked pretty dang big when the camera zooms out so you can see the town and where the 2 parts of the plane crashed.
4. How has Rosseau not visited them in her 16 years?
5. How do they have CDs and dossiers on people that landed on the island? They must have more access to materials than just the Dharma air drops.
6. Would Ben have really let Jack kill Juliet or was it just a bluff?
7. Why separate Jack from Sawyer and Kate? How do they intend to treat them differently?
8. Does the Dharma Initiative still exist in some form? Jack, Kate, and Sawyer seem an awful lot like lab rats right now. The h is Dharma does stand for heuristics which are reactions. What is the point in testing the reactions of these 3 individuals?
9. Do the Others inject themselves like Desmond did?
10. Will Karl appear again? Will other characters that were abducted by the Others make appearances? Will the Others get their comeuppance?

Only 3 more seasons (or so) to figure all that out and more.
