I like Rochelle a lot.
I could totally see her as a BDSM dom. She already wears kickass boots, she doesn't take shit from anyone, and fuck, she wears a Depeche Mode shirt, and all of their songs are about S&M (and about how God is either terrible or doesn't exist). That, and the idea of Francis being a sub is hilarious to me.
(I see Helen and Saxton Hale's relationship this way, too.)
