Ghosts is back for Season 6, and the Halloween special “Halloween 6: The Mirror” wasted no time shaking up Woodstone Mansion. The episode picks up a few months after Pete’s (Richie Moriarty) mysterious disappearance, and the fallout is far from friendly. As one character bluntly puts it, “He’s not our friend anymore.” That’s right — Pete’s memory loss has turned the lovable scoutmaster into a potential threat, and the show is officially entering uncharted territory.
In an exclusive chat with Collider’s behind-the-scenes series Set Stories, stars Asher Grodman (Trevor) and Rebecca Wisocky (Hetty) teased what’s ahead. While Grodman couldn’t reveal much about Pete’s arc, he did share his excitement for the show’s ambitious flashbacks — a hallmark of the Halloween episode. “If it were up to me, we’d be doing flashbacks left and right,” he said, praising the Montreal crew’s ability to build entire worlds in days. “The artists who work on this show, particularly the costumes and sets, are just incredible.”
For Wisocky, the episode offered a rare gift: multiple flashbacks that let her explore a younger, more hopeful Hetty. “I like getting to do Hetty before her voice became so leaden and wizened and sad,” she explained. “When she’s a little bit more hopeful and coquettish.” The costume team, led by Carmen Alie, outdid themselves with four or five different looks for Hetty, including a standout hairstyle with bangs. “The bangs, that was my favorite,” Wisocky laughed. “As a curly-haired girl, it doesn’t seem advisable, but it works with this one.”
But the real bombshell of the episode is the introduction of Hetty’s long-estranged sister, Margaret, played by Maria Thayer. Wisocky had long pitched Rose McIver for the role, but with McIver on maternity leave, Thayer stepped in — and she’s a perfect match. “She’s fantastic, very kind and generous and funny,” Wisocky said. The reunion forces Hetty to confront a painful truth: both sisters blamed each other for ruining their lives, when in reality, their fates were dictated by the men they did or didn’t marry. “It’s disappointing and also historically accurate that at this period, women’s futures were entirely in the hands of whether or not they married well,” Wisocky noted. “If only they had been capable of truly listening to one another and supporting one another, things might have turned out differently.”
As for Pete, his memory loss isn’t just a personal tragedy — it’s a seismic shift for the entire ghostly ensemble. The Halloween special ends with Pete firmly aligned against his former friends, setting up a season-long conflict that promises to test loyalties and rewrite relationships.

With Pete now a wild card and Hetty grappling with her past, Ghosts Season 6 is shaping up to be its most emotionally complex yet. The show continues to balance its signature silliness with genuine heart — a formula that Wisocky credits to the writers and crew. “The show does what Ghosts does best,” she said. “It’s ridiculous and stupid and hilarious and also really touching.”
