Accept No Substitutes is the sixth "episode" of C.E. Forman's Lost Season One (of The Lost Seasons series), written in fall of 1998. Like all of Forman's Lost Season episodes, it is written in quasi-script form with three Acts and commercials.
Mr. O'Neill throws out his back, forcing Ms. Li to call a substitute for his class. Margot Haworth arrives, a motorcycle-riding, swearing, against-the-rules type who preaches against conformity. Daria takes to her instantly, while Jodie is less impressed.
Margot Haworth is sometimes seen as a Mary Sue character, given the quickness with which she and Daria bond and the level of respect in which Daria holds her.
