ASUKA:“What are you, stupid?
Strange beings are attacking us.
If you're going through a fire, you've got to
brush away the embers, of course!”
UrsusArctos: The contrast between the two is pretty striking. Shinji seems to have had the Angel question in mind for a while, but waited until things were truly abnormal to wonder aloud why he was fighting Angels. Asuka, however, has zero curiosity about her enemy, and can't understand why someone would be curious about them either.
Zusuchan: It's little moments like these that showcase Shinji can actually be quite smart and thoughtful. It's a shame he refuses to really utilize those capabilities most of the time, though.
