The Wheel In Space starts off season six and features the return of the Cybermen. One of the cast on the Wheel is Errol Flynn's son - apparently.
There's some off topic explicit talk in todays episode, slightly linked with the 1994 Doctor Who year book. If you want to get to Wheel talk it starts around the 18min mark.
If you're new to Who and want to watch along with us, Sarah watched this story on Britbox where theres an exclusive recon and Mark watched the loose cannon reconstruction. The two existing episodes feature on the official BBC DVD 'Lost In Time'
