Word on the street is Morrison actually intended Scott and Ororo to have the affair! Luckily Lord Claremont called dibs on Ororo for X-Treme X-Men, and Morrison dusted off Gen X's Emma instead. While that shift did relegate Ororo to a satellite book and elevate Emma to heights she had never known before(and begun a whole decade of her taking a central position in the franchise), I don't think the fandom would have survived a Ororo-Scott-Jean triangle(nor would it have even made much sense for those characters coming off the 90's).
