Misato looks nervous. Shinji stretches to try and peek.
KnightmareX13: Misato actually seems to understand what the data means, maybe she is smarter than we are led to believe.
thewayneiac: Do they ever actually say she isn't all that smart?
Azathoth: Hey, you gotta learn something in college. I wouldn't have picked her for a science major, though...maybe she learned a thing or two from Dad?
Kendrix: Note that Shinji shows an acute interest in the gibberish on the screen even tough he probably can't understand it. One of the first signs that he spends more time thinking about what's actually going on around him than it initially seems like. He doesn't ask or investigate because he lacks the confidence, but he does privately wonder about what he's fighting and why.
