As for the mom being the original smokie, and MIB being able to kill her before she spoke, that doesn't fly because the rule isn't "before they speak each time", it is only upon first meeting. For eg: you can't have locke/Smokie talk to you today, then tomorrow you sneak up on him and stab him. I think it a recent episode someone mentioned that they needed someone smokie hadn't talked to yet.....
I am going with my gut on this one: we aren't going to find out squat and will be left with just as many questions as answers. I think the writers will leave the story open ended to make room for a spin off.
Maybe:
Lost in the desert: Jack and Kate buy a sport truckster and attempt to drive to Las Vegas and crash
Lost in a mall: they find an alternate reality in West Edomonton Mall
Really Lost: A plane load of people fly through an electrical storm and are stranded at a vacant airport terminal. Each week there is a whole new cast with no reference to the previous cast members.
I will say this again, (about all the questions not being answered). I don't really care any longer. I think the writers went way overboard in their mixed up plotlines. I read a book on writing techniques and one of the biggest no-nos in writing is when a writer does something that brings the reader out of the story. The writers of lost did this years ago. We no longer are wrapped up in what is happening, we're spending more time trying to figure out what IS happening and what it is supposed to mean.
Think of it as a murder mystery. A good movie makes you care about the characters, and become engrossed in the story. Last night is a great example: I didn't really give a shit that jacob really didn't want to be "the guardian", I was more interested in what questions it was trying to answer.
I find that with every episode, for every answer the writers give, they create just more. For example: sure, they explained how Jacob and smokie got on the island, but it created yet another question as to who their "island mother" is (at least IMO).
IMO the ONLY question that was (semi) answered last night was: the light is the source of all light (aka life) on earth. If it goes out, light goes out everywhere.
Well, if they're only going to answer one question per episode, they aint' gonna answer anymore because there's only 1 episode left before the finale.
