Theory:Doctor Who television discontinuity and plot holes/Attack of the Graske


 * If the TARDIS is following the Graske's trail, then how can it arrive before him?
 * It follows his trail to the right timezone and then has to wait around until he materialises.


 * The map of Victorian London looks more like a map of modern London.


 * If the Graske want to conquer Earth by replacing its population then why does the Graske we see replace a modern day person and then travel back in time to replace a Victorian person? Why not just try to conquer Earth in one era rather than two eras?
 * There was less people in Victorian Times. RPSMan 15:31, June 29, 2010 (UTC)


 * How does the Doctor know that the Raxicoricofallapatorian is from the Slitheen family?
 * Different families may have difference skin colors (Slitheens are green, Blathereens are orange, etc.
 * Its hardly likely that only one family in the whole of Raxacoricofallapatorius has green skin. Thats like saying only one family in the whole Earth is White or Black.
 * Yeah, but, they are different species so could still be green!
