"the most magical moment" in the entire episode and Ernie Vincze, the Director of Photography for the show, compared the scene's feeling to the 1980s science-fiction film Blade Runner. Davies characterised the reunion between Rose and the Doctor as "the biggest romance [the viewer] has ever seen" and joked that seminal films such as Gone with the Wind should have ended with a Dalek shooting the male lead. He had difficulty splitting up the characters for a second time for the necessity of the plot. He felt that "Rose has to be stupid to fall in love with Doctor #2" because "she's doing what the plot demands, not what she'd demand". At one stage he considered giving an explanation that Rose's dimension hopping and the Dalek's meddling with reality had contaminated her with "voidstuff" and that she would die if she stayed in her original universe. In the final episode it is enough for her to stay that the human Doctor needs her and is able to reciprocate her love. Porter felt that the climax of "Journey's End" indicated that "Rose's role as a sidekick has been completed" as she has a second Doctor to humanise, one who she can be equals with. Reprisals Though Davies had intended the serial to end with the Tenth Doctor visiting his former companions, he struggled with how to include Rose. An initial idea was for Rose to appear with her part-human Doctor in the parallel universe, where both would sense the original Tenth Doctor regenerating. However, Davies felt this would raise too many questions about their lives in the parallel universe. Davies's successor as executive producer, Steven Moffat, felt that Davies ended Rose's story in the perfect way by choosing to take it back to the beginning of her acquaintance with the Doctor. Piper's return for Doctor Whos 50th anniversary episode was confirmed in March 2013. Moffat wished to include Piper in the episode because he felt that she symbolised the rebirth of Doctor Who. As he did not feel comfortable adding to Davies's story arc, he chose instead to re-introduce her Bad Wolf persona. During the episode Piper's character has dialogue solely with John Hurt's War Doctor, and is unseen by the other characters, including the Tenth Doctor. Reviewers noted similarities between the characterisation of Bad Wolf Rose and that of a plot device used by Charles Dickens in his 1843 novella
