The Companion Chronicle Find and Relpace was so wonderful.
Katy Manning both completely killed as Iris, bringing top form hilarity and destroyed my heart as Jo with her reflecting on her relationship with the Doctor. Not to mention her Pertwee impression which was spot on for inflection and tone.
Also I was really glad that they didn’t do the obvious mistaken identity story that was there with those two. Not that I don’t want to see it but I like that it was unexpected.
Over all there was just a whole lot of heart to it and it was wonderful.
