The Sun newspaper is today reporting that Rose Tyler, Martha Jones and Donna Noble will all team up to help the Doctor to defeat the Master in the final 2009 special of Doctor Who. A BBC insider apparently said; “This will be the most exciting episode Doctor Who have ever done. We really wanted to get all the companions back on board as a fitting send-off to David. And of all the enemies for him to face in his final episode it makes sense for The Master to be the main one. Getting Billie to agree is a real coup, but she loved working on the show so much it didn’t take much convincing.” You can read the full article on The Sun's website here, but please note that at the moment these are only rumours and so they may not turn out to be true.
