The 31-year-old former star’s character is still dead, which gave her hesitation about coming back.
“Allison had such an amazing end to her life, I feel like bringing her back in any way might tarnish that beautiful story,” Crystal told BuzzFeed News.
So what changed her mind? She’ll be playing Marie-Jeanne Valet, an ancestor of the Argent family.
“Basically, Jeff [Davis, the showrunner] just said, ‘France in the 1700s,’ and I was in,” Crystal said. “He was definitely playing into my emotions. He knows that I have been dying to do a period piece and I love getting my head around different accents and different cultures. He didn’t even have much of a character worked out other than it was based on the Maid of Gévaudan. And I knew the legend, so before really knowing anything further, I said yes.”
