Kinda

The Doctor and his companions arrive on the planet Deva Loka, home of the Kinda people. While investigating the area, Tegan falls asleep under some mysterious wind chimes and her mind gets trapped in a shadowy realm where she gets antagonized by the Mara. Meanwhile, the Doctor and Adric get imprisoned by some colonists who have clearly started to go a little nuts. And, if you're wondering what Nyssa go up to, the answer is nothing. After a fainting spell at the beginning of the story, Nyssa is put to bed and is not seen again until everyone is ready to leave at the end of the final episode. Kinda isn't great. It seems like the writers couldn't come up with enough for the main cast to do, hence writing out Nyssa and sidelining Tegan for most of the story. That said, the giant snake puppet (yes, there's a giant snake puppet) is pretty cool, even if it looks a little rough.
