GHOSTS fans were left shocked when beloved character Mary left Button House at the beginning of season four.
But why did Mary decide to leave the show and what happened to her?

Why did Mary leave Ghosts?
The character Mary left BBC series Ghosts during season four.
She had been a resident of the haunted house since the very first episode.
But the character departed after actress Katy Wix decided to leave the show.
The writers of Ghosts told RadioTimes.com: “We were so lucky to have Katy Wix with us in Button House for four fun-filled series.
“She, ironically, breathed life into the role of Mary, as only Katy could, making her into such a unique, hilarious, and popular character.
“We’re sad to see her go but can’t wait to see what she does next.”
Co-creator Ben Willbond said on BBC’s Inside… Ghosts podcast about Mary’s character leaving: “We never intended for a character to leave, so it was very sad the whole process.
“The Ghosts are dead but they’re still living as ghosts, and there is that constant threat that they might go at any stage.
“That kicks off for the rest of the Ghosts this fear that oh, actually, we’re here for a long time but we could go at any time, pretty much like life!
“That is what the episode’s about.”
What happened to Mary on Ghosts?
Mary failed to make it into the afterlife after being burnt at the stake in the 17th century after being accused of witchcraft.
As a result, her face was smeared with soot and she constantly smouldered – and humans who couldn’t see her would smell toast if she passed through them.
During episode four of season four, Mary was bathed in golden light before finally ascending into the afterlife.
Before she disappeared she said “Ooh” and then floated up through the ceiling of Button House.
After she was gone the other ghosts were shocked and all of them dealt differently with her demise.

Kitty was crying and Pat comforted her by saying: “She’s looking down on us right now and saying there’s really no need to cry.”
Alison held a memorial service for Mary after seeing how much the other ghosts were struggling with her sudden loss.
During the service, she placed Fennel, a Loose Women magazine, and a photo of Mike into a basket and buried everything under a tree.
After the memorial, the ghosts had a little party because Mary would have wanted them to have fun together.
Did Katy Wix want to leave Ghosts?
Katy decided to leave Ghosts due to other commitments.
She had a massive workload during the filming of the show, including appearing in Stath Lets Flats, The Windsors, and Big Boys.
And in August 2022, Katy was co-writing a comedy series called Fat Camp, which is supposed to be about a children’s weight loss retreat.
