Well I'd hope she's not a Time Lord... otherwise she has dangly bits. But really Pix, what makes one a Time Lord/Lady vs just Gallifreyen? Going to the Academy? Do all Gallifreyens regenerate or just Time Lords? How is that controlled? See these are things I think were never answered nor will they be.
Yeah they were answered. Going to the academy and looking into the eye of harmony as well as the ability to regenerate makes one a timelord. (Please see security dudes in classic galifreyen episodes. They don't regenerate. They die.) The ability to regenerate was bestowed (or revoked) by the High Council and is a distinguishing characteristic of one who has attained the title of Time Lord. All these things are deduced watching the show.
