Truth or Consequences was a city in the state of New Mexico. During the 2010s, UNIT Chief Scientific Officer Kate Stewart visited the city to investigate a Zygon invasion, and was ultimately attacked by one disguised as the sheriff Norlander. The resulting Zygon then took on Kate's form and communicated with Bonnie, a Zygon who had taken on the form of Clara Oswald. (TV: The Zygon Invasion)
