You are correct about the Desmond situation. As an experienced sailor, he should have realized if the tide had turned him around. This is the largest (and dare I say only significant) problem with my theory. However, perhaps he has been drunk a lot. I dunno.

Walt is likely off the show because between seasons 1 and 2, he went through a growth spurt which can’t work with the show’s timeline. Hence, all of his scenes this season were changed and minimized and he is only shot at weird angles and waste-up in the finale. I think we’ve seen the last of them.

As for the different dimensions, I think that the writers are going to try to keep it closer to the real-world. Sure there will be some weird science stuff, but I don’t think there is going to be a multi-verse idea (although, I could be wrong).

The four-toed statue is a red herring, in my estimation. It’s probably part of an art project from the Dharma Initiative. After all, they were a hippie-type commune, and where is the rest of the statute? It wasn’t finished and won’t be OR it is finished (as an art project) and was only supposed to be a foot.

So, that covers most of your ideas. I don’t mean to sound like I know anything more than anyone else (aside from that Walt tidbit), but I think my theory makes decent sense.

I don’t think your currents theory is correct. First, Desmond said he sailed due west for a week, and ended up at the Island again. I can see being blown back or taken by tides/currents, but Desmond would notice this as a sailor. He was shocked when he returned to the Island, so it makes me think that he fully thought he was making progress towards Fiji.

Also, we don’t know yet if Michael and Walt will make it out to freedom. Walt’s strong psychic powers make it seem to me that we haven’t seen the last of him.

Let’s assume they do get out, though. My theory is that the island is a focal point for many alternate universes, and sits ‘outside’ of all of them as a result. The four-toed statue supports this, I think.

The Dharma initiative would need a wormhole or other portal in and out of that plane, reality, whatever. They would know that, if you sail at this heading, you’ll hit the wormhole and be free. Otherwise, you’ll end up back at the Island.

Finally, perhaps the electromagnetic explosions are strong enough to push through into our dimension and take down Ocean Air flights, for example.

Egads, I’m now gay AND a nerd.

The funny thing is, I usually come up with theories during the show, under the presumption that everyone is lying. Wifey Kim hates it, because I just tend to confuse her, and more often than not, I’m wrong. Doh!
