There seems to be a definite dark/light, good/evil theme with the discovery of the black and white stones with Adam and Eve, along with Locke’s talk with Walt about Backgammon and the light and dark sides.
Who are Adam and Eve, the skeletons that were discovered in the caves. Are they Dharma, probably not, more likely that they predate Dharma as Jack says that it would have taken 40-50 years for the clothing to decay like it had. From what we have found out in subsequent episodes Dharma have been on the Island for about 30 years, so that would most likely mean they are something else.
It was Ms Hawking, who we’d seen previously in “Flashes before your eyes” and it appears that she has her very own personal Dharma station in the depths below a church, where she’s using this big magnetic pendulum thing, an ancient computer (like in the Swan), and a bunch of complex mathematical equations to help Ben get those that left back to the island.
Charlotte finds out about the discovery of the Flight 815 wreckage while in Tunisia (where the polar bear was found). Based on the timeline of events on the island, and the Find 815 ARG the wreckage was found approximately in early December 2004. Why was there a Dharma polar bear in Tunisia, and why did Charlotte seem to recognise the Dharma logo? Both are questions for another time.
