[SPOILER] Plot Discussion Thread *Spoiler Alert*

[Corbent]

I was reading carefully the whole timeline Kein assembled (Thank you very much). And there's this one note that is very interesting and I feel it holds the answer to who is in the "Iron Lung". I'm not sure how, but I am sure it has to be Mandus himself and no one else.

The note:

Spoiler below!

27th December 1899

I am halved, I am bisected. I placed my feet in the stirrups of childbirth and I hung upside down and the great blade of history cut me in two like a butchered pig and my guts fell onto my children and smothered them in my love. Each half of me still living, but the guts kept falling onto my children. So we each went our separate ways and one half built a machine instead, to hold his hate in and to keep his heart beating. And the other fell into a sleep, to blunt the pain. And then he had terrible dreams and when he awoke, the other had made ovens and killed and skinned and cooked all of those he held dear. And thus, holding onto his guts, he strode forth to find himself and make himself whole again.

This note talks about the separation of Good Mandus and Evil Mandus.

"So we each went our separate ways and one half built a machine instead, to hold his hate in and to keep his heart beating. And the other fell into a sleep, to blunt the pain."

From this I conclude two things: First the man in the iron lung (more like a cryogenic chamber to me) is one of the two "Manduses". Second, the third heart is Mandus' heart as well.

I have two possible theories:
1.- Mandus made the machine to contain his evil side, then he went into cryogenic sleep to numb the pain of his wrongdoings and guilt. In this theory the whole game is a comatose dream (making it so at the end you see yourself in the cryogenic chamber and the ending is just a symbol of rejoining both your good and evil side) and nothing really happened. This would also explain the temple setting in London which doesn't make much sense.

2.-Mandus physically divided in a mystical way (orb powers FTW), creating a sort of Doppleganger of himself which is pure evil. At some point good Mandus was able to subdue the evil Mandus, strap him to the chair in the ending chamber and took his heart out, then placing the corpse of evil Mandus in the cryogenic chamber. So the third heart would be from Evil Mandus. Evil Mandus' heart corrupts the machine and gains sentience, so the only way to repair the damage is for Good Mandus to replace the Evil Heart with his own heart, destroying the evil Mandus presence in the machine.
