By now you've seen the rogue coffee cup left in a scene of season 8 episode 4 of Game of Thrones. 

On Friday night's episode of The Tonight Show Starring Jimmy Fallon, Sophie Turner was ready to answer a video question from a fan. That fan was her husband Joe Jonas!

“Oh my god, hi Sophie Turner, I’m Joe Jonas. I’m a huge fan!” Jonas jokes in the video. “I honestly have a crush on you but I’ve got a big question for you. I watch a lot of Game of Thrones and I was wondering- you’re definitely responsible for that coffee cup, right?”

Her husband is referring to an image that has made its rounds on social media of Turner holding an identical coffee cup with her costar Bella Ramsey in a behind the scenes photo.

Fallon then jokingly blames Turner for the misplaced cup. She replies, “Alright Detective Pikachu... this is a spoiler for a couple of episodes ago, this girl dies!”

Turner went onto explain that everybody on the crew has the same cups. “It's a scene from the episode after she dies, so why am I holding this coffee cup? That’s in a different scene! And also, we all have the same cups for all of our water and tea and everything."

Turner then made her accusation, “So I’m just gonna go with... I mean, look who it’s placed in front of. Emilia Clarke. She’s the culprit!"

Fallon then asks if the cast has a group chat and what their reactions were. Turner says, “There was just one text and it was from Nikolaj (Coster-Waldau), who plays Jaime Lannister, and he just wrote, ‘Great episode. Is that a coffee cup?'”

Clarke even poked fun at the incident on her Instagram and shared an image of her holding a similar coffee cup from a previous episode.
