>>2724790There aren't any "versions" of Rei from NGE.
Rei III moves Rei's character forwards, happens naturally and believably, and touches greatly on everything past in Rei's character. In other words, it's still Rei Ayanami. Same name, same character, never a question about it.
Rei Q? Not so much. Rei Q isn't even Rei. Rei Q is patently another character, and another stab at the heart of Rei from the messed up directors/writers because they are still mad Rei is so much more popular than their own "faves". Don't need to watch Rebuild to figure out who that is.
Rei Q can't be described as anything but deliberate sabotage to ensure that Rei's character never fruition to anything whatsoever in the story besides an attack on Rei's character and image.
