I had a feeling that Jin was going to be alive. Don't know how Ben is going to prove to her that Jin is alive. Maybe he finds something about Jin during one of the time shifts. Ever since the people left on the island have been time shifting, I have been thinking that Ben must have figured this out and have been using that information to his advantage. Think about it, if Ben knows who is time shifting, then he knows a little bit about the future and then knows how to manipulate people, events, and future events.
I think Ben hired the lawyer to take Aaron away because he knew that Kate was going to be a problem with them all going back. With Aaron away from her, then he would have one less problem in trying to get them all to go back.
Right when Locke kicked over the debris and saw it was french, I was thinking that Danielle will come up sooner or later. You can almost count all the events that happened in the past on the island and they are flashing towards that time.
We have past events that the islanders are flashing to:
Yemi's plane crashing
Danielle's boat crashing
Can't think of anymore, but what other events have we been hinted at that has happened to the island in the past. Hopefully we'll get a flash to the time where the people built the 4-toed statue
