The Fifth Doctor and Peri

On TV, Peri met the Fifth Doctor in the previous story, and he regenerated in the very next, so it feels like she doesn’t know him very well, and Peri is most often thought of as a Sixth Doctor companion. Big Finish decided to change that, possibly because there weren’t as many Fifth Doctor companions available at the beginning, or possibly because Peri and the Sixth Doctor mostly bicker, and that gets boring on audio. Anyway, this is a short period of the Fifth and Peri before Erimem shows up.
