Doctor Who: The Metebelis 2

Well it's the 100th episode for the Metebelis Two and Ben and David are not in a celebratory mood. The lads are pretty disappointed by the series 11 finale and wonder what happens next? Opening music is "Barnacle Bill" composed by Ashworth Hope, which was the original theme to Blue Peter. Closing music is "Thirteen" by Segun Akinola.
