“The dread banshee has arrived.”

The third season of Chilling Adventures of Sabrina will include the death of a major character.

Showrunner Roberto Aguirre-Sacasa shared a behind-the-scenes photo from the set of the upcoming season of a mysterious woman in a black cloak, alongside the caption: “The dread banshee has arrived, but which Spellman will die?”

The banshee comes from Irish mythology, and is a female spirit who heralds the death of a family member by screaming her lungs out – Alyssa Milano memorably played one in the third season of Charmed. But a dread banshee? Who knows?

There’s four major Spellman’s in the series: Sabrina, Hilda, Zelda and Ambrose – is the show seriously about to chop one of them off? Obviously, it won’t be Sabrina, so it looks like it will be one of her aunts or her cousin…

The second season, or ‘chapter’ as they like to call it, debuted earlier this year to critical acclaim. Since the show’s debut, it has been lauded for its dark tone – in comparison to the original – and treatment of its LGBTQ characters.

The third instalment will see return of Kiernan Shipka as Sabrina, Lucy Davis, Miranda Otto, Chance Perdomo, Lachlan Watson, Ross Lynch, Jaz Sinclair, Michelle Gomez, Richard Coyle, Tati Gabrielle, Adeline Rudolph and Abigail Cowen.

It is expected to debut later this year. The series has also been renewed for a fourth season.
