I read your post, I suppose I just didn't make all the connections. I see what your saying, but I've always chalked up the exos having no memory of the collapse either due to rasputin assuming control of them or just the traumatic events of the collapse. As far as the retinal scans, the ghost says "or something kept them preserved". It's not to say they are the eyes of the one who actually awoke him. And we don't even know that Maya had golden age access to Rasputin. She calls it their supervisory warmind, like it is overseeing them. And based on the golden age card, it seems like bray is the one with the passcodes, not Maya. That said, you could very well be right. One day we will see I hope.
