Wilson has mentioned that the death storyline was not the way she wanted Allison to exit the Showtime series, so it’s possible the big story behind her exit may have something to do with that.
That’s certainly true considering The Affair presented two possible scenarios behind how Allison died.
Viewers will presumably figure out which scenario is the truth in the final season, although it’s possible they’ll never know the full story behind Ruth Wilson’s exit.
Wilson’s comments also come at a time where Hollywood as a whole is under a lot of scrutiny for incidents of sexual misconduct, and while it’s possible something like that could’ve happened here no information has been revealed to indicate that may be part of this “bigger story.”
