[The Sarah Jane Adventures] Whatever happened to Sarah Jane Smith and her adopted son Luke?

The official word is that her story goes on forever.

There have been no reference to her death yet on screen (like there was for the Brig.) so she is probably still out there, somewhere.

I hope they make a reference to it one day. It was just a little too soon after they made a big deal out of the Brigadier Stewart's death. (Making it the one act that stopped the 11th Doctor running away from death, re-introducing his daughter, having him come back as a cyberman).
