We already know she knows or at least recognizes CLAMP so that covers Dou, Wata, and the Warashis. Would she know anything American live action (ie CSI, iCarly, ect) animated (Avatar for when I bring Sokka in) or would she know Vocaloid at all? I figure everything else I have is just too obscure or too random for even a fourth wall breaker like her to know.
