UrsusArctos: Rather than bashing or blasting his way in like his children/siblings, Kaworu uses his A.T. Field to activate the keycard reader and let himself in. Very polite. And like chorus is singing at this point, "und der Cherub steht vor Gott"- "and the Cherub stands before God" - the cherubic Kaworu will now stand before the god (Lilith) on the cross.
