[SPOILER] Plot Discussion Thread *Spoiler Alert*

[TheBik]

I'm skeptical about the professor character's involvement. There were a couple dialogue sequences where he and Mandus were discussing the machine's purpose and he sounded more fanatical than Mandus did. He must have been in on it somehow. Could he have been the body we saw at the end?

I've actually been thinking something similar. Perhaps after Mandus killed the Professor, he was able to use his body as a vessel for the half of his conscienceness that he left in the machine (the professor and the engineer share a voice actor, after all). Why he was keeping the corpse in an iron lung, as if it were alive, I'm unsure of.
