Mawdryn Undead: Part Two

Nyssa and Tegan have become separated from The Doctor, both are in different times, both meet The Brigadier.

It's quite a complex story, there's a lot going on, plenty of different threads, lots of characters, and strands, but it's all cohesive, it doesn't go off the boil.

Two questions, who's that being Nyssa and Tegan believe to be The Doctor, and why has The Brigadier lost his memory?

Loved The Brig's flashbacks, so many memories, he really did see it all in his time at UNIT. They do a great job of making him look different, but realistic in both eras.

Valentine Dyall makes a welcome return as The Black Guardian, that voice was fabulous, I'm so glad they didn't recast him. David collings also impresses.

This is good stuff. 9/10
