Saying goodbye to Game of Thrones isn't easy for Maisie Williams.
ET's Cameron Mathison caught up with the 19-year-old actress on the red carpet at the SAG Awards in Los Angeles on Sunday, where she opened up about filming her last scenes for the HBO drama after stealing hearts as Arya Stark.
"It has been my security blanket and it's been a safety net," Williams explained of her fears after the show concludes its eighth season in 2018. "If I haven't worked, or if I haven't landed a role, I never beat myself up too much, because I've always got Game of Thrones."
"To not have that around is going to be really strange, but it's also really exciting," she added. "It means I can now shape my career and I'm not tied down to anything, and I can really make bold decisions."
Though season seven of the award-winning series has yet to debut, Williams is already thinking about Arya's big send off.
"I'm just trying to do the last few scenes that I have justice," she shared. "I'm just trying to shape Arya the way that I have been so far, and give her a nice arc to end with, and hope the people are happy with it."
But for now, the British actress is enjoying her SAG Awards reunion with her cast members, as the show is nominated for Outstanding Performance by an Ensemble in a Drama Series, as well as Outstanding Performance by a Stunt Ensemble in a Television Series, and Peter Dinklage is nominated for Outstanding Performance by a Male Actor in a Drama Series.
"It's so nice to see the other cast members and us all hang out. We don't really get a chance to all hang out all together as a group on set because we're all in such different storylines," Williams said. "But it's so nice to get to come to awards shows like this because we all just get to have fun."
As for whether other actors have approached Williams hoping for GOT spoilers, the actress says she knows better than to spill secrets.
"Lots of people do ask, but not that many people actually want to know," she teased. "I can tell that if I were to actually ruin a storyline for someone, they'd be pretty upset."
