The third of the Third Doctor’s on-screen companions (and yes I know the Brig and some UNIT personnel sort-of count) was Sarah Jane Smith. And of course she bridged the gap into the Fourth Doctor‘s era, and had various spin-offs as well. She even managed to meet the Tenth and Eleventh Doctors as well. Busy, busy!
Sarah Jane Smith
While looking into material for my Third Doctor themed month, I found this piece on Tor.Com (I haven’t spent much time there but will): There’s Nothing ‘Only’ About Being a Journalist: An Appreciation of Sarah Jane Smith. It’s by Tansy Rayner Roberts, whose other articles also look deserving of attention.
This article covers the TV timeline of Sarah Jane, misses out Big Finish and the comments are worth a read as well. Do take a look.
