She’s the Mother of Flagons.

“Game of Thrones” actress Emilia Clarke — who portrays Mother of Dragons Daenerys Targaryen on the hit HBO series — is responsible for the modern-day coffee cup that sneaked its way into a scene in last week’s episode, according to co-star Sophie Turner.

Turner, who was implicated in the scandal because she was previously photographed on set with a similar cup, threw her fellow actor under the proverbial horse cart during an appearance on “The Tonight Show Starring Jimmy Fallon” on Friday night.

“Let’s clear this up. That’s in a different episode,” Turner said of the on-set snap, which shows her holding a coffee cup while posing with actress Bella Ramsey.

“And also, we all have the same cups for all of our water and tea and everything, so I’m gonna just go with, I mean look who it’s placed in front of. Emilia Clarke. She’s the culprit.”

The steaming controversy fomented last Sunday when a paper coffee cup made a guest cameo on the fourth episode of the medieval fantasy show’s final season, entitled “The Last of the Starks.”

The wild anachronism sent fans into a tizzy online shortly after they spotted it during the episode’s 17th minute. HBO later digitally removed the cup, originally thought to be a grande Starbucks but later revealed as a simple craft-services beverage, from a version of the episode view-able on the HBO Go app.
