1. Locke is definately up to something.
2. The "Others" still have the French lady's son Alex and Walt (you could see him in the scene where they light up their torches).
3. Hurley knows Libby from somewhere and I think instead of being a psychiatrist, she was actually a mental patient.
4. What happened to Desmond?
5. I think that the man Jack was operating on (a couple of weeks ago) was in the orientation video.
6. In the same flashback the date on the Patient Chart was November 15, 2005.
