As a sorcerer, I would trade Ashara Zavros for Vette in an instant. It makes sense from a story perspective, as both the Inquisitor and Vette were slaves to begin with, and the former has numerous opportunities to be sarcastic as hell with everyone, which the latter likes. That and I can't stand Ashara and Vette is hilarious.
