[SPOILER] Plot Discussion Thread *Spoiler Alert*

Ok, there is one very strong argument in favor of the theory that Oswald's body is the one in the Iron Lung. Occam's Razor. According to it it can be Mandus, Professor or Father Jeremiah. But there is no indication whatsoever that it is in fact Prof. or Jeremiah, whereas there are all those notes about Oswald being split in two half one of which is sleeping. So, Occam's Razor, it really is Oswald inside the Lung.

Let's assume it's true. But when is he plunged inside the Lung? There's a lot of questions here, because on one hand he kills his children somewhere around 1st December (so he has to be human at this point), and on the other hand he says he was bisected (which must be the point where he is plunged in the Lung) and one half built the machine which can't be in December, because then he already knows that the Machine has to be destroyed.
It only would be possible if there were two Oswalds physically, one sleeping in the Lung and one possessed by the Orb, building the Machine and spilling blood.

Also, by the moment I can't abandon the idea of the Machine being a God which needs blood to enter our world. Because Oswald, even if we relive his memories, would not be able to predict the future (XX century) and would not tell to himself that he is the one killing dissidents, waging wars and so on (Machine's final dialogue).

Pretty much my option #2: The Doppelganger Theory
