Once again, I can't tell for sure what happened, the elevator crashed and Cbio transformed like Sanakan did some time ago. I have no idea where up and down was.
Seu got hurt but I didn't see a scratch, Mensab and he are on their way to that device to heal him. Ivy is not dead but torn apart and Maeve lost an arm, fight is not over, though.
Mensab is an AI but not the only one, there are 12 other caves from where AIs manage Toha Heavy Industries.
The people that lived there became cyorgs?
