Theory:Doctor Who television discontinuity and plot holes/It Takes You Away


 * The way Graham phrases "another planet", it makes it seem like the comic and novel adventures never happened. Is this perhaps a mistake on the part of the writers of the comics and the writer of the episode?
 * He’s been to multiple other planets on TV alone, so it seems like he may have just been simplifying things to avoid blowing “Grace”’s mind too much.


 * The storyline is similar to the 2009 German movie called The Door/Die Tür. The cave is a path to another world,  there is a moth/butterfly in the cave,  dead family members are on the other side, and a child realises there is a fake family member.
 * Not really relevant to the Doctor Who continuity.
