Synopsis
The strands of Donna's story begin to draw towards a terrible climax as she finds her life, her family, her entire world being devastated. Only one person can help. But this time it's not the Doctor-it's someone from a parallel universe, an old friend thought to be lost forever...

Story notes

 * This is the first story to feature Rose in the capacity of the Doctor's companion since Doomsday.*
 * Lucius Petrus Dextrus from The Fires of Pompeii says that "she is returning" when seeing the future. This is most likely a reference to Rose's return in this episode.
 * Billie Piper was seen at the end of Partners in Crime, as well as a short cameo in The Poison Sky.
 * Chipo Chung was last seen in the episode Utopia as the Malmooth, Chantho. She plays a human character in this story.
 * This is the 'Doctor-lite' episode of the series, similar to Love and Monsters and Blink.

Rumours

 * Donna has something on her back (referred to in Fire of Pompeii by Lucius) and is a Metebelis spider.
 * Since Rose is returning in this episode, then it is may be the beginning of a three part story. Thus Martha Jones, Jack Harkness, Mickey Smith, Jackie Tyler, Sarah Jane Smith, K-9, Davros, Harriet Jones or Dalek Caan could also return in this episode.
 * Gwen, Ianto,  Rhys or  PC Andy could make a cameo appearance, perhaps with Jack before he goes to help  the Doctor.
 * In Planet of the Ood when Ood Sigma said "your song will end soon" The Ood sang songs craving to be reunited with each other, and the Doctor's song of craving for  Rose will end soon so he will be reunited with her once more.
 * Rose and the Doctor will never actually meet in this episode. They may be able to see each other, but not be physically in the same place possibly because they are in Bad Wolf Bay. This is unlikely due to the YouTube footage of the Turn Left episode being filmed in Wales. It is more likely that they are in the same place because in Partners in Crime, Rose was shown to be leaning on the police fence.
 * In Utopia (TV story) when The Master says "as one door closes another must open" this could be a reference to this episode as one "door" to the Parallel Universe closes (DW:Doomsday) another must open.
 * It has been reported that the Doctor will not feature in this episode at all.

Continuity

 * In The Sontaran Strategem the Sat Nav kept saying Turn Left. The Doctor is also heard saying Turn Right not Left. This could have something to do with this episode.

DVD and Other releases

 * This is due to be released in the Series 4 boxset in November 2008 along with the rest of the Series.
