Mankind can re-form after Shinji rejects Human Complement Project, right?
There is a chance that Misato and the others could reform because a) Rei was already with them when they died and may have collected their souls even before HCP began (the ghostly images of Rei that hover above Misato and Ritsuko’s as they die; which is absent from Asuka’s “death”) b) During HCP Rei appears to all the dead bodies in NERV who died and they turn into LCL. That included Misato and Ritsuko; and yet, not Asuka… Personally, I don’t like the idea of them all returning – but I have nothing against it.
