It is a vain hope but I've always wanted to see Jenny from Series 4 of the new Doctor Who show up and meet the 11th Doctor. It would be interesting to see how the other characters react to her presence, especially River, and how she would fit in with them. At the very least, seeing how the Doctor deals with seeing her again would be worth the watch. What do you, my fellow Escapists, think? Would it make for a great episode or just a load of fan service with no real value?
