[So Porthos is hardly one who's scandalized easily, or one who can't appreciate a beautiful woman when he sees one. But this is Constance. So... when he actually gets a good look at her - aka, what she's wearing - he looks away abruptly, cause um he can kind of see your legs and other such things. And then he realizes that looking away abruptly like that makes it kind of obvious he was looking. So then he looks back, going for NONCHALANT cause yes hello]
