Según wikipedia son varios episodios donde ella se muestra lesbiana:

Thanks to Jane's close friendship with Daria—which, curiously, was not destroyed by the "Tom Triangle"—and her interaction with Alison in Is It Fall Yet?, Jane is sometimes developed as a bisexual or lesbian character, with interests in either Daria, Quinn, or Alison as female partners. The TV show's creators even play into this idea, with Glenn Eichler speculating in an interview that Jane might be "straight and curious."

Francamente me resultaría muy difícil saber en que capitulo dice esa frase, te puedo pasar el sitio donde lo puedes ver todos los capitulos Online; No es la única frase interesante que dice, Daria es lo maximo!*-*:
