With Sarah stunned by Kaagh, and the radio telescope under the Sontaran’s control, Clyde has no choice but to run for his life or become the subject for Kaagh’s experiments. He bumps into Luke and Maria, who help him escape the Sontaran and begin hatching a plan to regain control of the radio telescope to foil Kaagh’s plan. But Maria knows that they’ll need more help, and calls her father to tell him how to activate Mr. Smith in Sarah’s attic. Maria’s dad learns how to disable a Sontaran…but when he finds that his ex-wife has trailed him into Sarah’s house, he has to find a way to explain the fact that their daughter is doing battle with aliens trying to take over the Earth. If he can’t help Maria and the others to free Sarah and defeat Kaagh, he may not live long enough to report to his new job.

Notes: The Last Sontaran marks Yasmin Paige’s final appearance as a regular in The Sarah Jane Adventures, due to her school schedule. Mr. Smith sports a new appearance in this episode, possibly resulting from his reboot in The Lost Boy, though this wasn’t apparent from his appearance in the Doctor Who episodes The Stolen Earth and Journey’s End, which takes place between the first and second seasons of The Sarah Jane Adventures. Mr. Smith also appears to have a new sound effect straight from the vaults of the now-defunct BBC Radiophonic Workshop: the sound of the Hitchhiker’s Guide To The Galaxy being activated!
