– when Buffy returned for season five, some fans had to go back and check they hadn’t missed something. Out of nowhere, the Slayer had a 12-year-old sister, Dawn (Michelle Trachtenberg) , and Buffy and all her friends were acting as if she’d been there all along. In fact, Dawn was The Key to the hell dimension once ruled over by Glory (see J) hidden in human form. False memories of her had been implanted in the minds of all those who knew her (apart from the viewers). In the end, of course, she became as dear to Buffy as any little sister – so much so that Buffy sacrificed herself for Dawn at the end of the season K is for The Key
L is for Lucy Hanover - a former Slayer active during the 1860s who first appeared in ads for the series and again as a ghostly ally to Buffy and co in spin-off comic books and novels
M is for Musical – Once More with Feeling, the awesome musical episode of Buffy, in which the characters are compelled to sing their secrets by a groovy Devil-like figure who calls himself Sweet. The cast all sang their own parts on tracks ranging from strings-led musical numbers to all out rock songs, touching on subjects from death to bunnies
N is for Nerf Herder – the band that wrote and performed the frenetic theme to Buffy the Vampire. A tune to kick vampire ass to if ever there was one...
O is for Oz – skater dude, musician, one-time boyfriend of Willow – oh, and werewolf
P is for Potential – Potential Slayers, that is. A new Slayer is activated each time the existing one dies (Faith – see F – is the result of Buffy’s brief death at the end of series one - see D). All over the world, young girls with the potential to be the next Slayer wait to be called. They are unusually fast and strong but lack the power of a true Slayer. As the endgame approaches, The First's acolytes, the Bringers, are tracking down and killing all the Potentials they can, while the Watchers Council sends the survivors to Sunnydale to be trained by Buffy for the final showdown...
Q is for Quentin Travers - a member of the Watchers Council and not a fan of Buffy and Giles's close relationship or their unorthodox training methods. Rather than support Buffy, Quentin tries to make life difficult for her - until Buffy realises she is the one with the power and that the Watchers Council should be working for her
R is for Rhonda the Immortal Waitress - Joss Whedon's original concept from which Buffy evolved: “The idea of some woman who seems to be completely insignificant but turns out to be extraordinary," a chance to subvert the cliche of “the little blonde girl who goes into a dark alley and gets killed in every horror movie”. "Wouldn’t it be fun if the girl fought back?", thought Whedon. It is...
