Teaching isn't what she really has in mind. She'd much rather show someone up, although she's a bit reluctant to do it to Kaworu. Mainly because he's seen her vulnerable and there's something in her that doesn't like the idea of making an enemy out antagonizing someone who knows all about her. She's about to make a reply when she finally notices Kaworu's weapon. Her mouth stays hanging open for a second and the color slowly starts to drain from her face.

She still remembers the last time she ended up fighting with (and against) swords like that.
