When it comes to Game of Thrones spoilers, Joe Jonas‘ lips are (legally) sealed.

While discussing the upcoming final season of the HBO mega-hit on Good Morning America on Tuesday morning, Sophie Turner admitted her fiancé is one of the few people who know how the series ends.

“He was on set for most of [filming the final season], so he kind of figured it out,” said Turner, 23. “He had to sign an NDA.”

Turnersaid Jonas, 29, not only had to sign a non-disclosure agreement, but he also wasn’t allowed to take any photos while visiting production.

“He had to have full photo approval on set, his camera was covered up, everything,” she explained.

So does the actress have faith that Jonas can keep the secrets? Not so much.

“You can give him a call, he’ll probably tell you everything,” she joked.

After appearing in every season as Sansa Stark, Turner said she’s already grieving the loss of the character.

“I’m just coming to terms with it right now, it’s like a death in the family,” she recently told Harper’s Bazaar UK for her cover story. “I’m losing the character I’ve played so long.”

She added of playing Sansa, “Initially, I didn’t feel there was anything that stayed with me from all the things Sansa went through. But though I think it hasn’t affected me emotionally, I did start thinking about the domestic abuse and rape, and it spurred this little part of me that might be an activist.”

Game of Thrones returns April 14 at 9 p.m. ET on HBO.
