Please no spoilers!!
So I just reached Elizabeth and I don't understand shit. Where did I come from, on the boat? who were the two people on the boat? Why did I go to the lighthouse and get launched into Columbia? Why did I rescue Elizabeth? Who am I and what is my purpose?
It's possible that the mystery unravels later on, or that it is meant to remain a mystery LOST style, but this is way too mysterious, so much that I'm clueless.
(The following is a spoiler of the next 10 minutes after meeting Elizabeth):
Also, is it me or does Elizabeth go from worried and defensive to "let's dance mister Dewitt ahahaha" in a matter of minutes? She's pretty quick to trust a stranger who pulled her out of her home isn't she?
