"Original Post", in this case referring to the very first post of this thread.
Of course, there are going to be forced elements in stories like this, as well as big gaping holes in the story where not everything is explained in detail, but that's what leads to all this speculation and it's what I love most about this game.
I enjoy the analytical aspect of this game, to assess the characters based on what we see and to ascribe meaning behind their words and actions. It certainly can be considered "imagining" things about them that may not necessarily be true to try and make sense of it all, but that's fun for me.
