On the second day of the count down my true love sent to me,
two Petronella Osgoods
and a mad man in a blue box
in the 50th anniversary special The Day Of The Doctor, there were two Osgoods, one human, one a Zygon copy. In a hopeful gesture of inter-species friendship the zygon Osgood gave the human Osgood their shared asthma inhaler as only the human one needed it.
