Great to see an OCSM that loves Lost!
Interesting ideas, I can't imagine that Ben would
want Sayid to kill him, since self-preservation seems to be his goal above all else. But that's a pretty original concept.
I hope that we are going to find out more about thier relationship because there are still a few unresolved questions. Who were those people that Sayid killed, did they really work for Charles Widmore? I suppose it doesn't matter, it only matters that they were people that Ben wanted eliminated for his own plans. But we still don't really know if Widmore is the bad guy, or if he really should be the one on the Island, and not Ben. Did Ben kill Nadia or simply blame Widmore for it when he wasn't responsible either?
Why the sudden change in Sayid's character? Is it just because he saw the truth in what Ben said about him? I don't see how he has any evidence, above his own feelings to suspect that he was manipulated.
I talked a little bit about the relationship to past-present memories:
It would seem that "not being able to change the past" means not being able to change the memories of the people in the present/future. Since Danielle didn't remember Jin, I guess Ben won't remember Sayid or any of the others- despite the fact that there apparently is a photograph of all of them from 1977 hanging up on the wall
Daniel Farraday said that you can't change the past, and I guess we are supposed to believe him, but he thinks that for whatever reason Desmond can, and that because of their relationship, he can as well. I think that is going to be significant in upcoming episodes when we find out (as we have yet to) what Desmond is doing and what Daniel has been up to for the last 3 years on the island.
