The actress, who stars as Arya Stark, warned fans that they may not be surprised by the outcome of the hit HBO fantasy series.
But, she assured viewers, it will be “different” to what many expect it to be.
The youngster, who has of course read the scripts for the eighth series, revealed that she and her mum “cracked open a bottle of wine and made predictions about how it was going to end” beforehand.
“Neither of us was right,” she confessed, before teasing: “I don’t know if it’s gonna surprise people, but it’s just different to what you think it’s gonna be.”
Addressing rumours that the each episode of the final series could be feature-length, Maisie simply commented: “Milk it for all it’s worth, why don’t you!”
The 20-year-old went on to open up on how what she would like for Arya if she does survive the final run.
“For a lot of the previous season her emotions were very cut off, she just didn’t want to hear what her family had been through,” she told The Times.
“I hope in the new season I get a chance to bring back a bit more of that fun child that we fell in love with.”
It comes as Maisie hinted that there will be a bloodbath in the final run during an appearance on The Graham Norton Show.
When asked about the latest series, she spilled: “It will air next year, we’re still making it.
“It is so much fun now there is only a small group of us left and it’s exciting to know everything that is going on.”
The 20-year-old has seen her fame skyrocket since she first made her appearance in the hit HBO series in 2011, which has led to some rather odd requests from fans of the show.
“My character has a list of the people she wants to kill so people come up to me and ask me to recite the list and add their names at the end,” she explained.
While many stars of the show are remaining tight-lipped over what will happen in the eighth season, one hinted that they could return to kill the Night King.
In an interview with BBC Entertainment, Tom Wlaschiha, who starred as Jaqen H’ghar, teased he’d make a comeback.
“I think Jaqen certainly could kill the Night King,” he joked. “But you know, these things happen in their own time. So I cannot give you a date.”
He added that he believes Jaqen would “definitely” be proud of Arya’s skills – could they hunt the villain together
