Theory:SJA television discontinuity and plot holes/Invasion of the Bane


 * Sarah Jane has pictures of the newly designed Daleks yet they are different to the ones from Death to the Daleks and Genesis of the Daleks and she has yet to encounter these Daleks.
 * Assuming this is set after Doomsday, she may have got them from there, also she met the Doctor in School Reunion and he might have told her about the new Daleks there. Also, Mr Smith could have got them for her.


 * When Kelsey is being taken over by the Bane, Luke yells "Kelsey Hooper", not Kelsey Harper.
 * Sarah Jane refers to her name as Kelsey Hooper first (possibly not hearing Maria or Kelsey saying it right), therefore Luke assumes - as he only heard Sarah Jane call her it - that it is her name.


 * Sarah Jane incorrectly refers to the book of "Revelations" in the Bible, it's just "Revelation".
 * The term "Revelations" is commonly used by lay people to refer to the book.


 * Why would Maria go into town with Kelsey having known her for barely 2 minutes?
 * Kids can make friends easier and as she was new she may have been desperate to seem fun. Plus Kelsey was not taking no for an answer hence why Maria laughs nervously and is like, "What the hell?"

He might have pulled on it lightly.
 * When the Bane Davey is climbing up Sarah Jane's staircase, one of his tentacles pulls on a banister where some hats are mounted, and they don't even move.


 * Mr Smith looks different in this episode. His screen is more of a plasma and looks different in later episodes.


 * Just as computer users can change their computers desktop if they wish, Sarah Jane or possibly Mr Smith himself may have changed it. The Lost Boy reveals that Sarah Jane hasn't had him for long at this point. He may still be in construction.


 * When Sarah Jane is being escorted to the lift from Mrs. Wormwood's office her coat goes from in her arms to being worn in the space of a few seconds.
