This is the FINALE of Doctor Who - Trek Through Time III, The Quest For Kirk, If you haven't seen the first half of this episode, now might be a good time to watch it.
It's Christmas day again and what would be better than a nice episode of Doctor Who meets Star Trek. This is the last one of the series. I hope you all enjoy it.
