Behind the scenes

 * In the invalid source Doctor Who?, TV 21 put forward the Yarvelling and Zolfian Dalek birth theory to explain the creation of the Daleks. The Fourth Doctor disproved the theory by taking Sarah Jane Smith and Harry Sullivan to see Louis Marks, the true inventor of the Daleks, tearing a copy of the magazine in two to signify this.
