It's only a cave and some random woman, HOW is that a spoiler.
I prefer to go into a game 'dark', as in knowing as little about it as possible (bar, of course, whatever the demo shows), maybe I'm the only person who likes this. I'm not too fussed, angry or annoyed at the above details, but it has spoiled it a little for me, personally.
Well, knowing that you meet, and have to protect someone, also the location.
I guess you've never read/watched a review in your life then.
I know it's my decision to read it, and that I may end up knowing certain things about the game. To post details of what happens outside of the demo, inside 'the demo thread' is, imho, wrong, and they should be kept separately.
