Doctor Who show, as the story begins anew with each companion and she undergoes more change than the Doctor. The primary companions of the Ninth and Tenth Doctors were Rose Tyler (Billie Piper), Martha Jones (Freema Agyeman), and Donna Noble (Catherine Tate) with Mickey Smith (Noel Clarke) and Jack Harkness (John Barrowman) recurring as secondary companion figures. The Eleventh Doctor became the first to travel with a married couple, Amy Pond (Karen Gillan) and Rory Williams (Arthur Darvill), whilst out-of-sync meetings with River Song (Alex Kingston) and Clara Oswald (Jenna Coleman) provided ongoing story arcs. The tenth series introduced Pearl Mackie as
Before the Flood (Doctor Who) Doctor and Rose Tyler in the episode "The Idiot's Lantern". The name often appears on electronic equipment throughout the series, such as Martha Jones' television in "The Sound of Drums", and a shop with the same name is seen in "The Beast Below". O'Donnell mentions prior companions Rose Tyler, Martha Jones, and Amy Pond, as well as Harold Saxon and events from "Kill the Moon". She also mentions "the Minister of War", but the Doctor has no knowledge of this, surmising that this will be in his future. The Tivolian race previously appeared in the episode "The God Complex".
