If the Stark sisters' long-awaited reunion in this season of Game of Thrones made you emotional, you're not alone—Sophie Turner was right there with you. The actress teared up when she first learned that Sansa (her character) and Arya (Maisie Williams) finally shared a scene again, and apparently got on the phone with her costar when she first read the script.

"I read that we reunited and I rang her up and I was like, 'Oh my God, I just cried. Like, I can't believe this is happening, finally,'" Turner recalled in the newest episode of Thrones' behind-the-scenes series, Game Revealed.

Part of what made the reunion so sentimental was Williams and Turner's real-life friendship. The pair often document their hangouts on Instagram, they've shown their sisterly love on the red carpet, they costarred in a Carpool Karaoke episode, and got matching tattoos to commemorate their GoT casting.

"To have Sophie around on set again has just been the best," Williams said.

"It's' been so much fun," Turner echoed. "She's my best mate."
