So, just a few thoughts, comments, questions, etc.
- When the failsafe was used, are we to assume that there are no more electromagnetic charges that build up in the island? The whole point of pushing the button was to release small bursts so that it wouldn't build up too much. Now that there's no hatch, no need to regulate the flow of EMPs, that makes me think that the electromagnetic properties of the island were man-made.
- That said, we're also lead to think that the electromagnetic properties of the island are what cured Locke of his paralysis and Rose of her cancer, at least that's how I saw it. With the electromagnetic properties gone shouldn't they revert back? That is, unless it cured them permanently, and not just in a "you must stay on this island to stay cured" kind of way.
- So, finally, regardless of whether it's the electromagnetic properties, or the Island itself, or something else that can cure ailments of various people... how can Ben have tumors on his spine? Methinks the x-rays are a hoax....
