Osgood Box

The "Osgood Box" was a device given to Osgood and her Zygon duplicate by the Doctor to use if the ceasefire between humans and Zygons broke down after a peace treaty was arranged. The two Osgoods recorded a brief video explaining the Osgood Box and its abilities before one of them was murdered by. (TV: The Zygon Invasion) Blwch Osgood
