Theory:SJA television discontinuity and plot holes/The Empty Planet


 * Rani acts as though Gavin is so much younger than she is. He can't be that much younger than her?
 * Rani and Clyde are around 17. Gavin states he is 13 in Part 2. It would be perfectly normal for her to act the way she does.
 * Actually, 13 year olds and 17 year olds socialise perfectly normal with each other.


 * Clyde can't leave Earth because he was grounded by the Judoon. However in SJA: Death of the Doctor, Clyde did infact leave Earth.
 * The Robots left him there legally. The Doctor does not adhere to legal rules, especially when it affects the course of history itself.
 * There is nothing physically preventing him. The law says he can't leave Earth - that doesn't mean he actually can't. It just means he will be punished if he is caught doing so. In this story, the Robots just chose to leave him on Earth to avoid getting into trouble. The Doctor on the other hand, ignored it.


 * Rani and Clyde say they have no 'robot dog'. They are listing who has disappeared and correctly say that Mr Smith has gone as he is in fact alive so would also have been removed, but K9 is not alive; so there is no reason to assume that K9 would have vanished. The just assume he's gone which is stupid especially as they hadn't bothered to check. It would have been difficult to check him anyway as they would have to go to the university themselves, but they can't just presume he's not there without checking.
 * As you mentioned in your above "statement", they simply say that they have no robot dog. They don't. Whether or not K9 is still on Earth, he is not there to help them.


 * Why does Mr Smith not work once everyone has been removed from Earth?
 * Mr Smith is actually a sapient crystal called a Xylok encased in the computer interface. The Automatons removed every sapient organism on Earth as legally possible via the warp-shunt, which included Mr Smith.
