All through this episode Jen and I (my doctor who viewing companion) and I were calling Anna 'Lyra' and
really excited that she was in Doctor Who. So sadly, i don't remember her performance in detail. However on a second (third,
fourth....) viewing. Anna is great. It's hard to come into a show do a part for one episode and then leave and be remembered.
And in an episode where there are so many to be remembered (Simon Pegg, Tamzin Greig). Anna was brilliant, and when it was
discovered she was a freedom fighter, it gave her performace such a twist and made it all the better.
