Appeared in: The Day of the Doctor, Death in Heaven, The Zygon Invasion/The Zygon Inversion.

She's got the look. Question mark jumpers and Converse on feet. Long scarf around neck and geek chic glasses. Bow tie, erm, tied up with question mark collars. These are a few of the Doctor's favourite things. Plus, she's a dab hand at utilising his sonic sunglasses.

OSGOOD: Sorry?

DOCTOR: Just something for your bucket list.
