Continuity
"School Reunion" is the first appearance of Sarah Jane Smith and K-9 since The Five Doctors. It answers the question of where Sarah was left at the end of The Hand of Fear: Aberdeen. The bragging match between Sarah and Rose also references other stories: Sarah has met the Daleks, "lots of robots", anti-matter monsters, mummies, dinosaurs, and the Loch Ness Monster, whereas Rose has met ghosts, "Slitheen in Downing Street", the Dalek Emperor, gas-masked zombies, and a werewolf. The phrase "Slitheen in Downing Street" was later used in Revenge of the Slitheen by Sarah.

Famous quotes containing the word continuity:
“Only the family, society’s smallest unit, can change and yet maintain enough continuity to rear children who will not be “strangers in a strange land,” who will be rooted firmly enough to grow and adapt.”
—Salvador Minuchin (20th century)
“If you associate enough with older people who do enjoy their lives, who are not stored away in any golden ghettos, you will gain a sense of continuity and of the possibility for a full life.”
—Margaret Mead (1901–1978)
“The dialectic between change and continuity is a painful but deeply instructive one, in personal life as in the life of a people. To “see the light” too often has meant rejecting the treasures found in darkness.”
—Adrienne Rich (b. 1929)
