Ehm... are you sure about that?
At the end of the game she surely leaves that life behind if she ends up with the MC, but DURING the game she is still a prostitute even if we don't see her in action.
So much so that when the MC meets the early version of Victoria in that lift/elevator, he wishes her luck and tells her that he's met a wonderful woman who has the same profession as she, and that it will be up to her to decide to leave it. So...
Don't get me wrong, Carli is my favourite in DA, but Victoria is also my favourite in CoBD (together with Ellen) and I definitely see some similarities between them. They're both knockouts, they're extremely intelligent, and they have the chance to leave their sordid pasts behind them.
