Misato:“Why don't you go take a bath and scrub away what's ailing ya?”
Hexon.Arq: At this point, I would be extremely annoyed by Misato, as hot as she is. He's probably thinking, "What did I get myself into… or rather, what did she get me into?" Her attractiveness is probably the only thing other than his subdued nature that is keeping him from bolting for the door.
OMF: He's also been mentally wearied by Misato's excessive gregariousness. Introverts usually find social communication exhausting, and Shinji is probably ready to pass out by now.
HeWhoPostsStuff: This seems like an odd place to put the "camera" for this shot, with the plant obscuring a sizable chunk of the action. I'm at a loss to think of why they might have done that. Unlike the light in C-120 that served as a "conveniently-placed atmospheric censor device" (much like the lamp in Rei's room in a later ep), I'm not sure what the plant would be "blocking out" here…
