I think we all just need to accept that this was just a recap episode to explain everything to the people who don't get it.
I agree with a lot of you guys about incontinuity (like when Locke died and Ben told him Jack had just purchased his first plane ticket.... we knew that he had been doing that for weeks before Locke died... wtf?). I think most of this episode we just kinda need to take with a grain of salt, and think, well, yeah, that explains some stuff.
I'm sure next week will be much deeper. This was just an explanation. We're way above that. =D
