In one of David Tennant’s final adventures, a team of his most famed companions/allies is formed. The team consisting of Harriet Jones, Rose Tyler, Jack Harkness, Sarah Jane Smith, and Martha Jones come together to aid the Doctor in stopping the end of the world. This gallery of characters were iconic during the adventures of previous incarnations of the Doctor and Tennant’s edition of the Time Lord. Their presence in “The Stolen Earth/ Journey’s End” helps provide a storybook ending to Tennant’s run as the Doctor, but is it’s unfair to the characters that the viewers grew to love during the tenth Doctor’s adventures.
Rose Tyler traveled with both Christopher Eccleston and David Tennant’s version of the Doctor. She added continuity to a somewhat abrupt change to the iconic role. She anchored Tennant in the first few episodes of season two, and she also gave the viewer some continuity within the show. At the end of Tennant’s run, we are given closing points for Rose, Jack, Sarah Jane, Martha, and Donna. This bookend for the series was beneficial in that it gave the show a “mini-reboot,” but it hurt the show in that the eleventh Doctor didn’t have a continuity point from the tenth Doctor, and seemed very lost in his first adventure.
Rose was a dynamic character that the viewers already knew, and this made assimilating the new Doctor much simpler. In Matt Smith’s first episode, he acknowledges his former versions of himself, but not his former companions. This feels out of character for the Doctor, and it hurts the chance for these former companions to appear alongside the eleventh regeneration of the Doctor. Without watching ahead, I think this is a disservice to the characters that travelled with Ten, and it also hurts the mythology of the famous television show.
