Story notes

 * This is the first story to feature Rose in the capacity of the Doctor's companion since Doomsday.*
 * Lucius 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 last seen at the end of Partners in Crime.
 * Chipo Chung was last seen in the episode Utopia as the Malmooth, Chantho. She plays a human character in this story.

Rumours

 * Donna has something on her back (refered to in Fire of Pompeii) and is a Metebelis spider.
 * If Rose returns in this episode, then it is quite likely that it is the beginning of a three part story. If this is true, then 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.  It could also be a more ominous ending suggesting his death (and regeneration) or the loss of something else important to him, such as a companion, or the TARDIS.
