In Bill's first comic adventure, the TARDIS crashes into the heart of a Viking camp! But this is no interactive history lesson, and it seems that a terrifying alien force has taken hold over the icy kingdom. As the snow melts, the Doctor realises that he is about to face an unwelcome face from the past...

And in a one-shot adventure, the Doctor takes Bill and Nardole on a trip to an intergalactic supermarket, where they make an unexpected new friend!
