Ruby Baker
From Tardis Wiki, the free Doctor Who reference
Ruby Baker was a student at the Saxon Heights boarding school, when Missy had become a temporary head. She had been forced to wear a uniform resembeling Missy's costume, and had to give away all of her mobile communication devices, for Missy's plan to summon a Dæmon. However, Osgood realised Missy's plan and ordered UNIT to stop her, saving Ruby from almost being killed by Missy. (PROSE: Yes, Missy)
