I didn't notice her, but it's possible. I'd have thought someone else would have mentioned it by now, though.

She's a very Kovarian-like character, though. Superior and condescending to the confused and disoriented people she encounters, in much the same way that Kovarian was to Amy. I'd say she's a Moffat archetype, but I can't actually think of any other characters that he's written like them, so I may be wrong.
