Behind the scenes

 * Writer Steve Gallagher originally wanted to call the character "Yoni" but John Nathan-Turner asked him to change it as this was Indian slang for "a part of the female anatomy". (INFO: Terminus)
 * It is unknown what became of Kari and Olvir afterwards; they are last seen on-screen in part four destroying Terminus's control cables to ensure it no longer poses a threat to the Universe, and then having to work out how to get home.
