According to Michael in the preview for Two for the Road, the Others are not well armed and "we can take them." If this is the case, then do they know about the hatch and all the ammo/guns that are (were, thanks to Sawyer) in there? If they are part of Dharma (which I'm sure they are), then why aren't they in a hatch with lots of guns, etc? Guess we'll find out next week...
