Theory:SJA television discontinuity and plot holes/The Temptation of Sarah Jane Smith


 * Trickster was a name given by Alan Jackson. At the end of part 1, he actualy calls himself the Trickster. How did Alan know his name?
 * Perhaps Alan guessed his name (possibly one of many) correctly, or he may not have one and simply refers to himself by the name they know him by. In TV: Whatever Happened to Sarah Jane? Alan has plenty of time to get the Trickster's name off the Graske he has tied up in his living room. Also, the Trickster may have told Alan his name off screen as in TV: Turn Left the Doctor refers to the Trickster's Brigade which presumably was a reference to the Trickster.
 * Maybe he just chose that name after Alan named he this, just as Elton did in TV: Love & Monsters


 * Luke doesn't get questioned for his clothing, which was not in fashion in the 1950s, yet Rani does.
 * Her clothing was much more noticeably different for the period.


 * Sarah Jane's mother mentions that the Russians and Americans have been testing H-bombs left and right, but the first American H-bomb test wasn't until 1952, a year later.


 * Why was the fissure that Sarah Jane and Luke came out of, after Sarah Jane disabled the car, near Westminister Abbey, when the one they went through, and all subsequent fissures in an abandoned shop in a shopping mall?


 * Sarah Jane tells Clyde that if you change one tiny thing in the past, it has terrible consequences. But when Martha Jones worries about changing the future a tiny bit, the Doctor tells her not to worry about it.The Shakespeare Code (TV story)


 * Martha was an adult. Sarah Jane wouldn't exactly tell the teenage, troublemaking Clyde that he could mess around in the past without consequences.
