Cool for covering that up. Even though people come here knowing there are spoilers, that one is pretty huge.
Most people probably would have guessed that one, to be fair
Thanks Paddy, for the additional preview!
I'd agree to the comment about memory loss. In one of the videos posted, Simon is walking along the seabed. He encounters one of the submarine robots, inhabited by the conciousness of a man.
He seems to know he's a machine, but still says he experiences things like thirst and it's making him angry. I think a lot of the people were put inside machines against their will and are frustrated with feeling human, in the body of a machine.
