Christel Doctor Who of the Week - 11th Doctor Mistake

Although The 11th Doctor makes a brief appearance at the end of the first special. He is actually in the episode at the beginning. When the 10th Doctor crosses the road to get cash a police car drives past with the 11th Doctor at the wheel. This was actually a mistake, but I left it in as I noticed whilst the episode was uploading. I think now, knowing the overall arc for the specials that it works quite well.
