In the second season of the Irish hit “Bad Sisters,” the darkly comic and seriously murderous events continue.

Co-writer and producer Sharon Horgan plays Eva, the eldest of Dublin’s five Garvey sisters. Along with Ursula (Eva Birthistle), Bibi (Sarah Greene) and Becka (Eve Hewson), they decided in S1 that they had to rescue their sister Grace (Anne-Marie Duff) from a horribly abusive marriage to the sadistic and endlessly manipulative Jean -Paul. (Claes Bang).

Your “bad” solution? Murder – disguised as “accidental death.”

The second season begins two years later with a surprise: Grace has actually moved on and is newly married.

“Grace,” Duff acknowledged in a Zoom interview, “is such a lost soul, right? You feel like you don’t exist unless you’re in a relationship. And any relationship will do!

“So she is willing to join very sick people to find some kind of safety. It’s a big journey to know what your relationship with your new husband will be like. “He is very different from Jean-Paul, so it is very interesting.”

Duff, so memorable in films like “The Magdalene Sisters” and “Nowhere Boy,” won a British Academy Television Award and an Irish Film and Television Award as the wounded-bird-like Grace.

“She’s like a wounded bird, isn’t she? She has lost her wings and that is why she is tied to the ground. That’s his sadness, really. That she is trapped.

“She was trapped inside a very unhealthy marriage, and now she’s trapped inside this secret (of what she did).

“Although we see her full of joy and happiness at the beginning of season 2, we know that she cannot take flight because she is overwhelmed by this terrible guilt that she has and the knowledge that she will receive what she deserves.”

She is also constantly with a glass of wine. Is Grace a functional alcoholic?

“I think,” Duff, 52, responded, “that he desperately needs to be anesthetized. Because to continue moving forward she has to pretend that there is nothing behind her.

“And the way to do it for her is to make everything a little blurry around the edges. Which I think a lot of people are guilty of, right?

“We imply that she is losing control. It seems like you have everything organized. But in reality it is slowly falling apart.”

“Bad Sisters” had a phenomenal reception in its home country with weekly viewing parties. None of the cast members had signed on with any provision for another season.

“It’s extraordinary when you realize that something has taken off and is really loved by the public. You never know,” Duff added from experience. “You throw things out there and hope they stick. And this one really did.”

The second season of “Bad Sisters” premieres with 2 episodes on AppleTV+ on November 13.
