oh yes.. I have seen it all... but what I mean is... there is still no evidence in Maternity leave to say that there are NOT two different sets of others...

Dharma being one set of others... black rock descendants being the other...
I still don't think that when jin and and eko were in the jungle and we saw the low shots of people apparently primitive "barefoot" walking.. that that was NOT the Dharma others... I think there are more than just the one large faction of people on the island.. there could be more than two... (and there is something about needing to have children.. my guess with that would be because they can manipulate the island) hmmm...

all that maternity leave shows us is that the "dharma others" present themselves to the survivors as people who are "ALSO TRAPPED" on this island. for what reason? I guess we will have to wait another long time to see.
