Jacob: The Energizer Bunny (Part 1)

This is the first of my two part theory giving two different options of what Jacob might be.

Jacob: The Energizer Bunny

Now what do I mean by Jacob being "The Energizer Bunny"? As everyone knows, "The Energizer Bunny" is a rabbit that runs on electricity. That statement combines both parts of my theory. One being that Jacob, instead of hating Locke's flashlight in The Man behind the Curtain, actually used it to his advantage. The second states that it is also possible (in light of the Orchid orientation video) that Jacob is a future Locke.

I. The Flashlight
Here's what I think. It's obvious that Ben didn't want Locke to use his flashlight in The Man behind the Curtain, and I don't think it was because Jacob doesn't like light. My theory is that Ben didn't want Locke to use the flashlight because Jacob's power (that we saw when Ben was thrown across the room) comes from electricity. You all saw that Jacob has a pretty bare hut, without anything that might make electricity. That's because Ben is holding him captive in that hut, keeping him very weak because he is essentially powered by electricity. John turning on the flashlight gave Jacob a split second chance to try and escape, and lashed out. Locke ran out of the hut, making the electricity out of range of Jacob, and making him forced to calm down.
