Myths

 * The faceless being that Toby saw as a child was The Trickster
 * Some people believed that Erasmus Darkening may have been a Time Lord. Sarah Jane commented on Darkening`s manipulator having TARDIS-like qualities. Clyde made reference to some aliens looking human and used the Doctor as an example. He seemed obsessed with living forever as if he were a Time Lord on his last regeneration. His clothing was suggestive of Time Lord clothing. The counter argument is that the Doctor has indicated that he "would know" if there were other Time Lords still in the Universe. Erasmus was, however, trapped between dimensions, which it is hypothesised may have "hidden" him.

Filming Locations

 * The Haunted House in the episode was previously used in Series Four of Doctor Who in Forest of the Dead.

Discontinuity, Plot Holes, Errors

 * In Part One, when the Professor is taken, her scream can be heard, but the cameras she is using have no audio, as she earlier uses her radio to talk. (The fact that the she used her radio doesn't mean the camera had no audio. If she was still holding her radio button down when she screamed, the sound would have been transmitted back that way.)
 * Rani mentions that Haresh has been teaching Luke to play chess. However, in the previous story, there was a chess set in Luke's bedroom. (Luke could have been starting learning how to play chess at this point, and bought or was given the set)

Continuity

 * Clyde references the events of SJA: Eye of the Gorgon
 * Clyde mentions the Doctor, he previously met the Doctor in SJA: The Wedding of Sarah Jane Smith.
 * Professor Rivers previously appeared in SJA: The Lost Boy and SJA: Day of the Clown.
