Hi everyone! It's time for the second part of the two-part series of series four, in which it turns out that these aliens are trying to clone themselves and become the new race of Earth.
I'm super excited because Martha has been roped into whatever their next adventure is, and I have been such a fan of her chemistry with Donna that I can't wait to see what happens next. Where the hell are they going to go, and why is Martha so crucial when they get there?
Thanks so much for listening, and I will see you soon with a new episode!
