tv33: I love when Gendo responds like this. Rather than saying “Yes” or “No”, he make a statement implying that it will be done because Nerv exists. The idea that he will notsucceed does not even cross his mind, regardless of the fact that they don't have a pilot for EVA-01 yet and she has never even been activated. It will be done because it hasto be; there is no other option.
Reichu: I also like the attention to detail, namely, Gendo's little “pushing-glasses-up-bridge-of-nose” gesture. As someone who wears glasses (due to the fact that I'm ratheradverse to sticking things in my eyes), I myself must do this type of “routine maintance” several times a day.
Hexon.Arq: It's also a great way for a glasses-wearer to punctuate an obvious response without quite so much smartassery. “…dumbass.”
