[SPOILER] Plot Discussion Thread *Spoiler Alert*

[rotten]

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.

Well that's a very good explanation, I do like it, except for the thought that the whole game was a dream, that would be baffling.
On the second version... Why did he keep his evil twin alive with his heart out?
