Christel Doctor Who of the Week - River Song

Episode 5 of Christel Doctor Who series 2, Picnic at Asgard is not only written by my second guest write Burkey, but also features the enigmatic River Song. However, Doctor Song is also going to be in another episode this year. I can confirm that she will also return in the second part of the three part finale to this series. River will be featured in episode 12, Vault 101 and will reveal the doctor that she "knew all along" but then she's not the only one....
