The actress’ head witch Fiona Goode was Lange at her most devilishly cold and calculating, and even though the character died and was banished to hell by the end of the season, that’s hardly a reason for her to be kept out of Season 8.
So who’s to say Fiona can’t make a return, possibly in reference to a particular house where ghosts frequently reside?
After all, Madison also died during Season 3, and more than once.
While the immediate go-to answer in years past would have been “it’s less likely than Constance Langdon giving up her smoking habit,” Season 8’s crossover structure could possibly tip the scales in a more positive direction, even if it could mean a much more fleeting presence for Lange than we’ve seen in years past.
