First, I want to thank you for your website that allows me to get more from the visual masterpiece by Mamoru Oshii.
Second, let me add few thoughts about it. After watching the film, comparing subtitles and reading your site, (a) few things are clear for me. Ash is a character. We don’t know if she trapped in a VR (unreturned) or she is A.I., but I don’t think there is a difference for the creator of Ghost in the Shell. We have to play for her. The game and the outside world are the parts of the same VR, there are too many confirmations of that, and they all have been noticed by viewers and listed on your page. Class Real is our reality, how real is it – is the question that Oshii asks in all his works. Ash completed the mission in Class Real by killing Murphy, a bishop, therefore a program. Murphy’s body disappeared, because he belongs to another reality, and there are no “Mission Complete” messages in our world. Now she has an option to enter the next level, next reality, and we don’t know what is it, probably, another game, or the same old Avalon. And that I want for everybody  “Welcome to Avalon”, to see the movie.
There’s a lot to think on, and for me this gives yet another perspective through which to consider the film. Let’s start with the central point – Class Real is where we are.
Think on that a moment… Avalon shows us that Class Real is one more layer of reality, layer of illusion. Thus all of our reality is suddenly called into question. Is there an exit from Class Real that most of us are unaware of, or going further are we but constructs like the support team on Ash’s mission with Stunner and Bishop? Just when I thought I’d seen all the angles on Avalon this comes along… Thanks to Vadim for sharing this idea
