Saturday 26 April 2025. The Well. The surprising return of a decades-old monster leads not only to the urgent revision of a long-dormant TARDIS Wikia page, but also to an unexpected addition to the current season of 500 Year Diary. So join us, as we join Steven B for one more visit to a diamond planet called Midnight — it’s The Well.

Monday 1 December 2008. Enemy of the Bane. We return to Bannerman Road this week for the second coming of Samantha Bond as Mrs Wormwood, and she’s just as wonderful as you would expect. We also get the second coming of Kaagh the Slayer as well, at no extra charge.

Saturday 4 June 2005. Boom Town. This week, a New Series villain returns for the first time just six weeks after her first appearance — it’s Blon Fel-Fotch Passameer-Day Slitheen, wonderfully played by Annette Badland. Hannah Cooper and Pete Lambert join us.

Monday 7 September 1987. Time and the Rani. Another classic 80s villain makes her first reappearance on Doctor Who this week. But what will four serious teenage fanboys make of the fact that she has decided to dress up as Bonnie Langford?

Saturday 4 October 1986. Mindwarp. This week, the 1980s brings back its most iconic original villain (possibly) to face off against the Sixth Doctor for the second time. But is the reunion a success? Kate Orman joins us again, to discuss Mindwarp.

Thursday 5 January 1984. Warriors of the Deep. This week, the Earth’s original inhabitants wake up from hibernation after about a decade, put on their best fibreglass vests and samurai outfits, and invade an undersea base at 0.5× speed. The Silurians and Sea Devils are back — but why?

Monday 17 January 1983. Snakedance. This week, the people of the planet Manussa are about to discover that all their ancient myths are true, and that their own thirst and dissatisfaction are rearing up to strike them in rubbery serpentine form. Kate Orman joins us to discuss the second coming of the Mara.

Saturday 22 February 1975. The Sontaran Experiment. It’s cold and rainy this weekend, and so we’ve decided to catch up with Mark McManus and spend the day larking around Devonshire, falling down holes, and generally hiding from Kevin Lindsay while he brings the Sontarans to the screen for the second time.

Saturday 25 January 1969. The Seeds of Death. It’s Invaders from Mars this week, as the terrifying monsters we thawed out in 5000 AD last year make an early appearance on the Moon just sixteen years after the visit of the Cybermen. Their goal: to cement their position somewhere on the top ten list of recurring Doctor Who monsters. Jeremy Radick joins us as we try to work out exactly where.

Saturday 11 February 1967. The Moonbase. We’re walking on eggshells this week as we await the arrival of an army of marching Cybermen, approaching the Moonbase with a dastardly plan to change Doctor Who for ever. For the better, on the whole.
