The Emmy-nominated star and co-creator decided it would be “almost criminal” to deprive her characters of a second season.

Duff, who plays Grace, says her character is "just trying to stay above the water" after the events of season one.

In honor of the stellar show’s return and the loss of a Very Good Bad Sister, Duff spoke with Decider about the emotional roller coaster of filming her final scene, working with Owen McDonnell and Fiona Show, what the role has meant to her, and her excitement to watch as a fan moving forward.
