>>2192752It could be because of the fragmentation of her soul. Rei 01 seemed mature beyond her years, like an adult speaking from a child's body, wheras Rei 02, despite being much older, both developmentally and chronologically seems a bit more like a teenager, a very serious, disciplined one, but not as aware. Kaworu I would assume has maintained one body since being "birthed" by Second Impact, and has been under the control of Seele the entire time. He would necessarily need to be instructed and molded. He is probably privy to more than Rei 02 ever was. Rei senses she has another self in the Eva, but is never actually told this. Rei probably knows hardly more than Shinji does, despite spending more time with Gendo.
