It’s the final part of the Black Guardian trilogy and this time it’s all about the race! But we’re not on Earth, we’re on a ship, a *space* ship. Who will receive…Enlightenment?

So, the suspicious Turlough has joined the TARDIS crew and immediately strands them on a spaceship. Not only that, but a leper ship! And as he’s joined, we have to say goodbye to Nyssa…

An old friend and an old foe return in this episode, as both the Brigadier and the Black Guardian reappear. Plus there’s a mutated alien and a schoolboy trying to kill the Doctor. It’s all happening!

Oh dear, the Mara’s back, and that’s not good news for Tegan. We travel this time to Manussa, where the darkness from the places of the inside manifests itself once more. Let’s (snake) dance!

It’s the start of the 20th anniversary season, and we head back to Gallifrey where an old enemy is trying to get back into our universe. The commander of the guards looks a little familiar too…

What better way to mourn Adric’s death wiping out the dinosaurs than by taking a trip to prehistoric Earth! Sweet irony! How is the mysterious Kalid involved, and who is he? The answer will shock you! (Because of how ridiculous it is).

Well, we’ve reached *that* story now. Yep, the one with the silent credits at the end of part 4. We both knew it was coming, and here it is. At least we know what wiped out the dinosaurs.

It’s back to the 1920s for this episode, as we get involved in a murder mystery at a country house. Adric eats, Tegan dances, and Nyssa has a double. And obviously the Doctor gets accused of the crime.

Back to Earth again for this episode, and it’s the 17th century this time. Our intrepid crew meet an out of work actor and encounter some aliens who put paid to something the Doctor holds dear.

Take a trip to paradise with us as we travel to Deva Loka. So calm and tranquil until, as often happens, a snake ruins it - a very literal snake in this case. You can’t mend people! Or can you…
