Get excited, people who watch Doctor Who children's spin-off The Sarah Jane Adventures (I don't know who you are, but apparently you exist), because former hysterical idiot Josephine Grant is blundering her way back to the Doctor Who universe! According to the Doctor Who News Page, Katy Manning will reprise her role in an episode of SJA, written by Russell T. Davies himself, and also guest starring Matt Smith (himself). It made sense to bring back best-ever-companion Sarah Jane Smith, but Jo? Really?
Some back-story. In 1968, at the end of Season 5, producer Peter Bryant and script editor Derrick Sherwin introduced the character of Zoe Her(r)iot. She was supposed to be a genius-level astrophysicist from the late 21st Century, but, as was the fate of many a promising companion, she was quickly reduced to the roles of screaming and asking stupid questions. When planning 1970's Season 7, Sherwin didn't know whether the actress would stay. When she did leave, he essentially created another Zoe (a phrase that will be funny to anyone who's been watching Caprica), giving himself a second chance to properly give the Doctor an intelligent scientist as a companion. This time they got it right, and the resulting character, Liz Shaw played by Caroline John, remains in my opinion one of the series' best companions. Sadly, this was not the opinion of incoming producer Barry Letts, who felt that no one wanted to watch two scientists natter away, and that what the Doctor really needed was someone to "hand him test tubes and tell him how brilliant he was," which is exactly what the Brigadier tells him at the beginning of Jo Grant's first story, Terror of the Autons (8.1).
When, a couple of weeks ago, I suggested the writers experiment with not-alienating ways to bring back elements from the "classic series" to tell a good story, a greyer Jo insisting "But Doctor, it is the Age of Aquarius!" to a whole new actor isn't quite what I had in mind.
