Over the last few days I listened to the main range audios 198 The Defectors, 199 Last of the Cybermen, and 200 The Secret History, in which the Seventh, Sixth, and Fifth Doctors respectively find themselves suddenly somehow in the place of the Third, Second, and First Doctors respectively, trying to convince old companions who they are, trying to sort out the events they find themselves in, and trying to work out what happened to pop them into the wrong parts of their timelines. None of them exactly blew me away, but overall they were enjoyable. The combination of 7 and Jo Grant was particularly fun.
