I guess there were elements of that early on, but the reason they put her in a lot of promos is more because the character is popular. Honestly, they hit the goth much harder than the sexy. She is much more slotted into little sister/surrogate daughter - and occasionally falls into a sort of petulant or spoiled little girl persona because of that. But what they hit most of all in the show is that she's really excellent at her job. Anyway, the actress will be 50 next year, so though the character is still excitable, she's mellowed a bit from the first few seasons. She does wear short skirts and platforms and dog collars, but she also sometimes wears coveralls.
