10 Quintessential Doctor Who Moments From The 12th Doctor
5. Preaching To The Zygons (And Humans)
The Zygons are an alien race that can morph their bodies to look like humans. Zygons had been living on Earth for years, with only The Doctor and certain high-level UNIT officials knowing of their existence and keeping the peace through regular meetings with their ambassadors.
Then it all came crashing down. It only took the knowledge of the Zygon’s existence for the human race to hate them. And it only took being exposed for the Zygons to hate us. So, how did The Doctor stop a war that for a moment looked like a certainty? By giving each side a 50/50 chance to blow up the entire planet, of course.
Well, the bomb was more a means to an end, and not the end itself. Plus it was 100% fake—that’s probably important information to have. What really prevented the war was a show-stopping speech by The Doctor pointing out the finer points of prejudice, hatred, and why any species with hopes of surviving for more than a century should avoid such destructive concepts.
