Relative Dimensions was the seventh story in the fourth series of the Eighth Doctor Adventures, produced by Big Finish Productions. It was written by Marc Platt and featured Paul McGann as the Eighth Doctor and Sheridan Smith as Lucie Miller.
It served as Big Finish's 2010 Christmas special release and featured Susan and Alex Campbell (portrayed by Carole Ann Ford and Jake McGann respectively). In this adventure, the Doctor intended to spend Christmas with Susan and Alex, his great-grandson whom he had met for the first time in the audio story An Earthly Child. But a present he got for Susan a long time ago, in the audio story Quinnis, may jeopardise the perfect Christmas he had promised Lucie to make it up to her for their previous disastrous Christmas described in Death in Blackpool. This story was the only story on television or audio where the Doctor celebrated Christmas with his family.
Publisher's summary Edit
Christmas is a time for family, they say — which is why the Doctor has invited his grand-daughter Susan and great-grandson Alex for Christmas dinner in his time and space machine. But who, or what, is the spectre at their yuletide feast?
Venturing deep into the dark heart of the TARDIS, Susan uncovers her past, Alex is told his future — and the Doctor finds himself caught in a deadly dangerous present!
