I've always got the "good v. evil" theme from this show but last night it was very blatant for me. Jacob and NotJacob on the beach - Jacob wants to see the good in everyone, help them find their path, NotJacob sees that people are not so good and wants to manipulate and control others to do his bidding and eventually kill Jacob so he can take over.

The ship at the beginning - that was the Black Rock right?
