I see your point, and ditching her pants when she's in some else's apartment, much less all her clothing, surely makes Tai at least a closet exhibitionist (probably more, much more, but at least that). Having Marten accompany her to get her privates adorned works, to me, on both levels. Sure, she gets a chance to get Marten an eyeful, but Tai also gets to tell him she's doing it in the first place, when Marten might never have known otherwise and probably didn't want to, and now he will always know she has the piercing. I predict in the future Tai will write a memoir with an homage to Douglas Adams: Tai Fighter Tell-All: Everything You Never Wanted to Know about Me But Are about to Be Forced to Find out.
Oh, and perhaps you capitalize them because they are definite, distinct Qualities.
