Doctor Who: Gallifrey Public Radio Keir Hansen, Jay Witten, Haley Malle, Julie Hansen

The monsters are most definitely within the walls of Finetime as the Doctor and Ruby try to help from the other side of a display screen.

With the Doctor gone, Ruby is left alone with an unidentifiable stalker and a world seemingly turned against her.

Tensions are sky-high in a deep crater as Ruby tries to help the Doctor contend with a landmine, an overly 'helpful' medic robot, and the war-profiteering Villengard Corporation.

The delightfully insane Maestro intercepts the Doctor and Ruby's visit to the Beatles' first recording session, and alters history by stealing the world's music.

Ruby's new adventures with the Fifteenth Doctor begin with a monstrous bedtime story made manifest on board a space station full of infant refugees.

We're joined by friends Ly and Nathan of Pixel Who to ponder what historical encounters the incoming Fifteenth Doctor might have that would be the most astounding, entertaining, or even explosive.
