LOST Notes

JUST watched the most recent episode last night...holy SH!T!

And got all caught up but can't find the damn season premiere anywhere....what the heck do I do?

I want to go in and read more of this thread (haven't wanted to because I wasn't caught up)....

But I'm just wondering 2 things after all this:

a) why is Sayid doing Ben's dirty work
b) why the heck the Others are at odds with the Dharma gang to begin with....
