Even K9 is to put in an appearance, says the Daily Star, in an episode where they may not even be enough room in the TARDIS for all of the Doctor’s companions.
Of course, there’s no official confirmation behind the rumour – and it’s long been said by Doctor Who writers that having too many companions is a plot mistake which simply brings the story to a halt – so we’ll all have to wait and see.
If Ben Kingsley is to be brought back as Davros, it would seem something of a shame to drown out the character in a fan-pandering companions’ reunion.
Doctor Who has recently been confirmed for series five – though with a gap year – and no less than three one-hour specials. Also rumoured is a multi-Doctor story for Children in Need.
