She literally had her entire body pressed up against him in the nude in a high-tension situation... and he didn't pop a boner?
Yeah, I know she is really generic-looking, but her proportions are adequate. She is worst girl because she has unpleasant opinions of glasses and looks boring... not because she is lacking in the curve department. I'd figure for him to have no physical reaction at all, he has to have the most severe erectile dysfunction ever.... or be gay.
