Unlike many fans, the 33-year-old is actually on the cast of the HBO show — so, you'd think it would be hard for her to enjoy the series like everyone else!
But on Tuesday's Jimmy Kimmel Live!, the actress said she is still able to avoid spoilers — by only reading parts of the script that involve her character!
Dormer explained that after she joined the show during it's second season, she wanted to go back to "feeling like a fan," so she stopped reading other characters' storylines! Clever girl!
Though the actress did manage to drop a little spoiler about Margaery's story when she discussed how she filmed in Ireland and Spain for the upcoming season! We guess gurl eventually gets out of that jail cell we last saw her in!
The Forest star also dished on how the show runners collaborated with author George R.R. Martin on where to take the stories now that the TV series has outpaced the books!
