Sorry to dredge all this up again but as its come up whilst discussing the Big Finish audio series which was sadly left on a permanent cliffhanger I just thought I'd mention RTD's comments of how he had discussed ending the TV series with Lis Sladen had she ever chosen to leave.

I'm doing this from memory so if anyone with access to the relevant issue of DWM cares to make any corrections or additions please feel free.

Not long before he left for America RTD was sat with Lis and asked her to let him know if she ever wanted to stop as he said he had one last story in mind to write for her. At the end, after making sure all the kids were alright, she would've gone up, into the stars.
