Revelations continue. Sigma and Diana are Phi parents. They got trapped in the bunker in one of the timelines, and sent of “fax”. Of their twins to the past to save them. Phi has a brother, Delta. This also establishes an obvious paradox that Diana gets a brooch from the ashes of Phi that got trapped in the immolator, then gives it as a memento to her daughter, Phi, who will tell Diana later that she got it from her mother.
Zero is also the founder of Free the Soul, the terrorist cult from previous game. So Zero = Brother = Delta.
Another twist that I didn’t expect is there’s just one ward. From the beginning of the game teams are told there are three wards, and they can only communicate in one direction by sending messages. And that when they vote, they do it simultaneously, proved by their watches. In fact, their watches were with a 2 hour delay from each other.
