I have the best theory for the numbers. I developed it today with my friends at school. You know the guy who played connect four with Hurley and mumbled 4 8 15 16 23 42 all of the time.time. Well, we think that he was with Dharma which explains why the numbers were on the Hatch. Now, if you are still following, he was captured by the Others and brainwashed just like Claire. Somehow he escaped, and just like Claire,Claire, he remembers only a few things over time.time. The only thing he remembers is the Numbers.Numbers. He mumbles them over and over so he won't forget them, and thats why he's in the mental institution. Makes since, huh. Tell me what you think.

Poking Holes: Why the Others wouldn't have just killed him? (They were unbearably close to killing off Charlie; with reference to the following "support" point --mbm2007--) I also doubt that they would brainwash him. And if they would, they'd wash him good.

Support: The Others didn't kill him just like they haven't and didn't kill Walt, Michael, Jack, Kate, Hurley, Sawyer. They brainwashed Claire,Claire, so why wouldn't they brainwash him? And remember how Claire started to remember things. Well, so did he.
