Rei gazing at Shinji, completely devoid of emotion.
thewayneiac: "Oh yeah. You're the wuss who almost made me pilot."
Reichu: (035~040) What is the purpose of this prolonged shared gaze/long awkward silence? My own take is that it helps reinforce one of the prominent themes in NGE, which is the division between people, the way in which we are all inherently alone. Here, both Shinji and Rei apparently have things to say to one another, but neither takes that step forward. For Shinji, it is due to fear — as the script itself points out, he is "running away" from Rei; he does not speak because he is afraid of rejection of any sort. As for Rei… I couldn't even begin to speculate. She comes off to me as the type who would sooner stare you down than say anything, but I really don't know why she does.
Keisuke-kun: In the whole series there are many examples of communication breakdown. Which is funny, 'cause most of the time Japanese are like "Retsu Komyunikeshon" (yes, they do say that -_-).
