Nyssa & Adric are taken to Monarch where Adric, taken in by the leader, co-operates but Nyssa resists. Adric is sent to ask the Doctor to admit Monarch to the Tardis while Nyssa is taken away to be turned into one of Monarch's robots. Tegan is appalled by what's happening on the ship and wants to leave but the Doctor gets her to remain in the quarters while Bygon shows him the bits of the ship Monarch has kept hidden. She argues with Adric, seeking the Doctor, and accidentally knock him out before fleeing to the Tardis to try to get it leave, eventually succeeding. The Doctor is show the mobilliary where the poison is kept and Nyssa is being converted. They free her but Persuasion apprehends them, removing Byron's control circuit and sentencing the Doctor to death at the hands of the Greek gladiators.
What I remember most about this episode from when I was younger: I was ill and missed it. It basically fills in the story a bit and pushes Tegan over the edge.
Shall we have some more comparisons with the The Black Hole? (see episode 2 for all the ones we've already found)

None of the guest cast have previous Doctor Who form but several are quite well known. Philip Locke playing Bygon was the assassin Vargas in the James Bond film Thunderball while Burt Kwouk, playing Lin Futu, should need no introduction at all. He also appeared in James Bond films, in his case the original Casino Royale, Goldfinger and You Only Live Twice. On the big screen he's most famous as Cato in the Pink Panther while contemporary BBC viewers would have seen him in Tenko with former Doctor Who companion Louise Jameson. In recent years he was the narrator of the spoof Japanese betting show Banzai.
Playing Monarch is Stratford Johns, an actor well known for role as Inspector Barlow in Z-Cars which he reprised in Softly, Softly and several spin offs from that. Paul Shelley, playing Persuasion, has a long television career to his name including an appearance in Blake's 7:Countdown as Major Provine. He's the brother of Francis Matthews, the voice of Captain Scarlet. Annie Lambert, here playing Enlightenment, has also had a long career in television which includes a recurring, but unnamed, role in Space 1999.
