Although the stars of Game of Thrones have been sworn to secrecy about the final season, many of the cast and crew have accidentally let a few things slip as to what we can expect—at least emotionally.

Hannah Murray, who plays Gilly, said Season 8 is “not like a fairytale happy ending.” Lena Headey, who plays Cersei Lannister, admitted that “everyone cried at one point” (Kit Harington, a.k.a. Jon Snow, cried twice). And Emilia Clarke, who plays Daenerys Targaryen, thinks the finale will divide fans—an opinion she shares with co-star Sophie Turner, who plays Sansa Stark. So while we may not know who's going to live or die, we should at least be prepared to stock up on some tissues. And, if Gwendoline Christie is right, you may want to pre-book an appointment with a therapist.

Christie, who plays Brienne of Tarth, believes that Season 8 could be extremely emotional for some fans. "You're going to need therapy," she boldly told E! News at the premiere of Robert Zemeckis's Welcome to Marwen, in which she stars alongside Steve Carell, Janelle Monáe, and Eiza González. "I think just the show ending is going to send all of the world into professional help."

"I think it's going to make me incredibly emotional," Christie continued. "We're all emotional about the fact that this is the end, and this is the end of something incredibly significant for all of us, and it's been a truly incredible thing to be a part of."

Although we will soon see the end of Game of Thrones, the exploration of Westeros is far from over. The prequel series, rumored to be called The Long Night, begins filming in early 2019. In the meantime, the final season of Game of Thrones will premiere in April 2019.
