After just a couple of episodes, The CW’s new “Charmed” reboot has already set up some big mysteries. One of the biggest questions that the witches have is why Macy was led to believe her mother was dead, and actress Madeleine Mantock already knows how the mystery will unfold.

“I would love to tell you because I think it’s so cool, but I probably can’t,” Mantock told International Business Times at New York Comic Con earlier this month.

However, the actress, who previously appeared in “Into the Badlands,” revealed that the writers were very excited to let her in on their secrets.

“So we had our kind of introductory meetings and chats with everybody,” Mantock explained. “[A writer asked,] ‘Do you wanna know stuff? Do you not?’ I said, ‘Oh, I don’t know. Just tell me what you think I should know, what would be helpful.’ So he told me some stuff, and then he literally, like, he was sitting on a secret. He was doing this like ‘Well, hmm, maybe I shouldn’t tell you that.’”

Of course, Mantock couldn’t turn down the information after the writers seemed so clearly enthusiastic about what was planned. “I was like, ‘I feel like you should tell me because it looks like you really want to.’ And so he told me and I was like, ‘[high pitched noise] That’s really cool.’ I felt really, really pleased that I get to play with that at some point,” she teased.

Though “Charmed” is based on the original series that aired from 1998 to 2006, it isn’t necessarily taking storylines from the show. Macy’s personality seems much like Prue (Shannon Doherty), but her introduction as a long-lost sister reminds longtime fans of Paige (Rose McGowan).

However, it doesn’t seem like Macy was a secret baby that her mother had with her white lighter and put up for adoption. Instead, it appears Macy was raised by her birth father, who lied about her mom dying. Why would he do such a thing? Why didn’t her mother find a way to get her back?

These are questions Macy certainly wants answered, as fans saw in last week’s “Charmed.” When she believed the trickster was her mother, she was anxious to know what really happened, but the demon couldn’t give an actual answer. Fans will have to keep tuning in to discover the real story behind Macy’s mysterious past.

“Charmed” Season 1 airs Sundays at 9 p.m. EDT on The CW.
