Hi everyone. This is my first time posting, but I've been a lurker here for a while. I just finished the game a couple of days ago and from the moment I entered the Citadel I had the distince impression I was missing something, or something was wrong. Things kept throwing up little red flags, yet oddly enough I completely forgot about it once I met the Catalyst. I initially chose Synthesis so didn't see the "Shepard breathes" scene, and was left after the credits feeling, again, vaguely unsettled. Once I looked into the Indoctrination Theory everything made sense. I find it more plausible that the IT was at least partly Bioware's intention, than the idea that they suddenly lost their minds and wrote a nonsensical, out-of-nowhere ending. Anyway, it's always great to come on here and see all the little clues you guys dig up. There's one thing I've noticed, and I don't think anyone else has mentioned it, but when you choose the Destroy option, as you're approaching the tube, does anyone else hear the shrieking of the Beam faintly in the background? Or is it just me?
Also, I was looking at analysis of the "breathes" scene and the rubble surrounding Shepard. While most seeme to agree that it looks like concrete and rebar from London, others pointed out that the Catalyst chamber had wires and tubing that resembled rebar, and some of the architecture could be mistaken for concrete in the right light. I had an idea that maybe this was intentional. We know the final scene was heavily choreographed, which means we have to assume nothing is mere coincidence. Could it be then that the materials of the Catalyst chamber resemble the London rubble because Shepard is still there, and his mind is creating the area out of his surroundings? Others had pointed out more similarities between the chamber and the Beam area which would support this.
Finally, what exactly do you guys think the EC will be? Assuming the IT is correct, will it be explained? Or will the EC extend the indoctrination process, showing us the "consequences" of our choice: Control, Synthesis, or Destroy, at least as they would appear in Shepard's mind. Maybe there would be another hint for those who chose Destroy?
