>>2791627Like you say Rei is not really submissive, and Kaworu is a 1000 times more fake, idealized and contrary to NGE's so called point. But they have no problem pushing him.
And I'd say Rei & Shinji are not idealized at all. They were two introverts that that were drawn to one another but struggled to make a connection until eventually they did. Meanwhile Kaworu as character in relation to shinji earned nothing.
