Just because you finish the game doesn't give you the right to post spoilers about the final story.
I originaly just changed the title. But then decided that it's unfair to those making their way through the game who deserve to find this out on their own.
In other words, don't post a spoiler just because you find out about it. Reply to posts and help people get to it themselves but putting spoiler tags around one of the biggest plot twists will not be allowed.
