This is an odd little thing. Donna comes home after some harrowing experiences with the Doctor. Her mum, Sylvia, is as acidic as always. Then it stops.

I was somewhat irritated that this was stuck on Twitter/X as a "social media exclusive" and not included with the Donna Noble: Kidnapped! box set. I can only guess that the first episode was a bit too long so they had to cut something, and this is one of the spare bits which the Big Finish team decided to re-purpose.
