I've seen many comments like this and I might as well address it as a whole:
Why does it not matter that we won't get answers? These questions have been forming throughout the entire series and have been integral to the story of the show. I keep reading about character drama and all that jazz and I have to wonder how can you have character drama with not story. That's the problem I'm having with the show. Character Drama should not be repetitive, but should evolve. The last few episodes felt like everyone standing still. I'm tired of seeing characters go through the motions and want to see the characters reach that final step. Personally, I think it will be severly cheating the viewer if we don't find out anything. Speculation be damned, theories be damned, and subtilty be damned. Get on with it already.
