While a guest on Jimmy Kimmel Live, the actress revealed she not only knows how the show ends, she's also told someone about it!
"I was supposed to be here for a week, but they were like 'you have to come back and shoot the show now,'" Maisie said, before saying they still have "endless amounts" of filming left.
"It's a mammoth task this year, it's huge," Maisie continued, being careful not to reveal too much.
"You live your life in fear of revealing something," Jimmy noted, to which Maisie laughed, "absolutely," before going on to say she's read the scripts and knows "how Game of Thrones ends."
"I was just in my bed," I think, Maisie says of when she read the finale's script.
"It's just surreal, being on a show for so long, and it also having the following that it does, everyone's waiting for this moment and then you read it and it's just incredible."
She went on to say that she sent her mum the scripts, but that the show's producers had told them not to show anyone.
Anyone know Maisie's mum's number?
