Ep 22. Planet of the Spiders: Part 2

The episode, "Planet of the Spiders: Part 2," is the conclusion of a thrilling adventure in Classic Doctor Who's eleventh season. As the title suggests, the Doctor and his companions find themselves on a planet inhabited by intelligent spiders who have been using a giant crystal to enhance their mental powers. The spider queen, Metebelis, has her sights set on Earth and plans to use the crystal to take over the minds of every human being.

In Part 1, the Doctor and Sarah Jane Smith arrived on the planet to investigate a mysterious blue crystal that the Doctor had acquired on a previous adventure. They soon discovered that the crystal was from Metebelis Three and that its power was being harnessed by the spiders. Meanwhile, back on Earth, the Brigadier and his team discovered that the spiders had infiltrated a Buddhist meditation center run by one of the Doctor's old friends, Lupton, who had been possessed by the spider queen.

In Part 2, the action picks up right where Part 1 left off, with the Doctor and Sarah Jane trapped in Lupton's embrace and the spider queen closing in on them. However, they manage to escape and return to Earth, where they team up with the Brigadier and UNIT to stop the spiders from taking over the planet. The Doctor realizes that the only way to stop the spiders is by destroying the crystal, but it is heavily guarded.

In typical Doctor fashion, he hatches an elaborate plan to distract the spiders and sneak into their lair. With the help of his trusty sonic screwdriver and a little bit of luck, the Doctor manages to destroy the crystal and foils the spider queen's plans. However, not before sacrificing something very dear to him.

Overall, Planet of the Spiders Part 2 is an exciting and action-packed conclusion to this two-part adventure. It takes on themes of power and control, with the spiders using the crystal to manipulate the minds of others. The Doctor, as always, is the heroic figure who stops the threat to Earth in his own unique way, making for a thrilling conclusion to another episode of Classic Doctor Who.
