Doctor Who: 15 Cool Details Peter Harness Just Revealed About The Zygon Invasion

7. Kate's Original Cliffhanger Included Creepy Zygon Caterpillar Babies

In the finale of The Zygon Invasion, Kate is cornered by a Zygon disguised as a police officer, which reverts to its proper form and attacks her.

Originally though, her ending was a lot more disturbing.

In an abandoned script page shared by Harness, the police officer pushes Kate into a dark side room. Here, she starts to hear some unexplained thudding, scratching and scraping sounds, setting her on edge. It's then revealed that she's being attacked by a gang of Zygon babies, which actually look like overgrown, clawed, lumpy caterpillars.

Thankfully, this nightmarish cliffhanger was axed, and our evening was not ruined by the sight of those gigantic, slimy creepy-crawlies dropping from the ceiling.
