In Winter on Earth, the Doctor and Romana track Khapsis energy to a park, where they meet Rodney Barton, being mimicked by the energy. The Doctor tries to hypnotise him and learn information while Romana goes into the park, tracking the energy. Barton tells the Doctor about the beast that keeps everyone away from the park, and they follow Romana in. She tells the Doctor they need to leave because it's too dangerous. The Doctor sees she's not wearing her scarf and the image fades away. The water of the lake becomes a face and telepathically communicates with the Doctor. He tells it it's stolen the soul of the entire park, the trees and animals, and will consume the city, goading it by insulting it's non-threatening appearance. It warps itself into a screech-owl and attacks him as he throws his scarf at it, containing a piece of dwarf star alloy. Because it's so dense, the Khapsis energy compresses itself over and over again to mimic it, freeing Barton and Romana and being small enough to keep in a box. They drink mugs of tea before the Doctor and Romana leave as the universe goes about its business.
- The Doctor says they will deposit the energy on a small backwater in the Alpha Ursae Minoris system.
