I mentioned it in my above post.Originally Posted by Joshua001
Rei is a clone of Yui (Shinji's mother) and Lilith. So yes... it is brought up in the series that Rei does have rather distant memories of being Yui.
In answer to mechataku's question... Lilith is the second angel.
Lilith is that giant white thing that is down in Terminal Dogma on the cross... which everyone thinks is Adam until Kaworu points it out otherwise. She is said to be the mother of humainty, and was the first wife of Adam whom was exiled from Eden in Jewish mythology. Rei was also made from her, LCL is her blood and during Third Impact, all human souls return to her.
14. I think I finally remembered the berserker thing too... mechataku is right, but it also has to too with the being (soul) inside the Eva (in Unit 1's case - Yui and in Unit 2's case - Kyoko (Asuka's mother) and their will to protect their child.
Also when Unit 00 went nuts, it's been a theory that part of Naoko (Ritsuko's mother) is inside that Eva. Which would explain why Unit 00 seems to go crazy every now and then whenever Rei or Shinji is inside it..... since Naoko did hate Yui after all.
