Jacob and his nemesis discuss the Black Rock, a good look at the four-toed statue [UPDATE: Taweret]

Jacob leaves the four-toed statue chamber to check his wicker fish trap and then cooks a fish he finds in it on a rock. As he sits on the beach eating it, he looks out at the Black Rock sailing in the distance. A man in a dark tunic walks up behind Jacob and asks if he can join him. Jacob asks him if he wants some fish and the man says he already ate.

Here's the transcript of their intriguing conversation.

Jacob: I take it you're here cause of the ship.
Jacob's enemy: I am. How did they find the island?
Jacob: You'll have to ask them when they get here.
Jacob's enemy: I don't have to ask. You brought them here. Still trying to prove me wrong, aren't you?
Jacob: You are wrong.
Jacob's enemy: Am I? They come. Fight. They destroy. They corrupt. It always ends the same.
Jacob: It only ends once. Anything that happens before that, is just progress.
Jacob's enemy: You have any idea how badly I want to kill you?
Jacob: Yes.
Jacob's enemy: One of these days, sooner or later, I'm going to find a loophole my friend.
Jacob: Well when you do I'll be right here.
Jacob's enemy: Always nice talking to you Jacob.
Jacob: Nice talking to you too.

As the other man gets up and leaves, the camera pans up to give us a complete look at the four-toed statue, except for a direct view of the front. There is still some speculation about what mythological creature the statue is supposed to represent.

[UPDATE: According to a re-cap of the episode released by ABC, the statue is the goddess Taweret. I guess everyone can stop speculating now. Taweret was a patron of childbirth and a protector of women and children. Her husband was Apep, the ancient spirit of evil. Click each of their names to learn more about them.]

So. Jacob seems to be the one that brings people to the island. Does that mean that Oceanic 815 was brought there by him and not Desmond not pushing the button in the Swan station? Why can't Jacob's mysterious friend/enemy kill Jacob? Jacob seems to think that with every group of people that come to the island, progress is made. The question is, what is Jacob making progress towards? What is his goal in the end? And one more. Who is the other man? With the contrasting white and black attire, does Jacob represent good and the other man evil? There could be a million other questions asked about this scene, but I'll leave the discussion to you.
