Lady Christina

Lady Christina is the upper-class thief from “Planet of the Dead,” the one who steals for fun and challenge, because she doesn’t need the money. Which is ethically dubious enough that the Doctor didn’t want her on board the TARDIS, but also didn’t mind her escaping arrest in a flying double-decker bus. Once Big Finish had the rights to new-series content, it made sense that they’d start looking to secondary characters, even ones who’d only appeared once. As with Jenny, I wasn’t originally interested, but I eventually picked these up on sale. Christina’s Earth-bound setting allows her to intersect with UNIT, and that’s a good development.
