As an aside, I just listened to the most recent podcast (for "Follow the Leader"), and Cuse and Lindelof settled the matter of what is and what isn't canon for once and for all (for those interested, it occurs about two-thirds through). According to the showrunners, the *only* thing that is to be taken as canon is the show itself--not the alternate reality games, not the comiccon stuff, et cetera. Therefore, anything outside of the show, that for example has "explained" the numbers, is not to be taken as canon. Also, the podcast has an interesting question posed by a fan, regarding who is good and who is evil. In response, Lindelof shouts out a few names, and Cuse says whether they are good or bad. I'll list them here, but beware, there might be a spoiler in here: Hurley=good Kate=good Richard=haven't decided Frank=good Sayid=bad (though he backtracks a little and says it could go either way--perhaps he made an "oopsie" and revealed too much?) Jacob=good (though they were joking in the podcast that Jacob is a 60 foot man made of flame, so this could be a joke, too).
