>>2244729>Rei's soul is still in EVA-01, silly. Rei Q is Rei without her soul.Rei isn't Rei without her soul. Like the rest of the clones in the tank, they aren't Rei. They're spare parts, things that do not live. Flesh without a will, sentience, mind and yes, a soul.
If Rei presides within EVA01, Rei Q is not Rei.
