OMF: Ritsuko is curious about the relationship between Shinji and Gendo, but the fact that she asks Fuyutsuki — who seems to know a lot more about the subject — may be an indication that the topic of Shinji is taboo around Gendo. And/or that Ritsuko doesn't really have much of a relationship with Gendo outside of the bedroom.
Hexon.Arq: I'm curious to see what this escalator looks like from the side. I can't recall ever seeing the escalators from any other perspective other than from straight on. For the steps to possess that much length, there must be a hell of a structure under there.
