I've only watched it twice now but both times I've wanted to watch 'School Reunion' straight afterwards.
It is quite sad esp as it is so clear the character really doesn't want to go, but I also like the fact that SJS is left upbeat after realising the Doctor has made a mistake. Wonder how long that lasted after she discovered where she really was!
I fully agree with this!
Ending with her chuckle that he STILL couldn't get it right, brings a smile to a sad moment.
And I'm the same, always want to stick School Reunion on next!
