episodes "The Stolen Earth" and "Journey's End" (2008), which crosses over from Torchwood and The Sarah Jane Adventures. When Daleks invade Earth, Sarah Jane is summoned along with UNIT officer Martha Jones (Freema Agyeman) and Torchwood leader Captain Jack Harkness (John Barrowman) by former PM Harriet Jones (Penelope Wilton) to help The Doctor save the universe. On the Dalek ship Davros (Julian Bleach) recognises Sarah Jane from their encounter in the classic series' episode Genesis of the Daleks. In The Sarah Jane Adventures second series (2008), Maria moves away to America in The Last Sontaran, and Sarah Jane befriends new neighbour Rani Chandra (Anjli Mohindra) in The Day of the Clown; the same episode features flashbacks to Sarah Jane's (Jessica Mogridge) childhood in her Aunt Lavinia's home. In The Temptation of Sarah Jane Smith, Sarah Jane saves the lives of her parents, Eddie (Christopher Pizzey) and Barbara (Rosanna Lavelle) in 1951; by doing so she plays into The Trickster's hands, creating a post-apocalyptic alternative universe in the present day.

In series three (2009), Sarah Jane makes a new enemy in the body-stealing alien Androvax (Mark Goldthorp) as well as a lukewarm ally in the form of the interplanetary police force, the Judoon (from Doctor Who). In the second two-parter, Sarah Jane is able to recover K9 full-time (reflecting a real-world deal struck with the creators of the children's series K-9). In a crossover with the parent show, Sarah Jane reveals her intention to marry her secret fiancé, barrister Peter Dalton, in The Wedding of Sarah Jane Smith. However, Dalton's involvement in Sarah Jane's life proves to be a scheme of The Trickster. The Doctor gatecrashes the wedding to foil The Trickster's plot to make Sarah Jane give up on alien hunting, and
