'Game of Thrones' fans spy possible Starbucks cup in season 8 episode 4

Sunday night's episode of "Game of Thrones" left viewers with a lot of questions for the remaining two episodes of the long-running series.

Did they really have to do that to Missandei? Is Jaime going to fight for Cersei or against her? And -- wait -- was that a Starbucks cup in front of Daenerys?

The first part of the episode showed everyone up at Winterfell celebrating their (well, Arya's) victory over the Night King with lots of drinking, carousing and canoodling.

That sequence also set up the growing tension between Daenerys and Jon Snow now that they both know Jon's true lineage. One scene shows Tormund quite literally splashing his praise on Jon, setting up the contrast between Jon and Daenerys, who has grown increasingly isolated.

Daenerys can be seen in the background watching Jon being praised. And that's where fans believe a Starbucks cup was inadvertently left in a shot, sitting to the side of actress Emilia Clarke.

"The latte that appeared in the episode was a mistake," HBO told ABC News. "Daenerys had ordered an herbal tea."

Fans quickly took to Twitter to see if others had seen what they saw.

Some weren't quite as convinced.

Still, of course, fans came in with the jokes and art.

Starbucks also took the time to playfully respond, mentioning its signature Dragon Drink on Twitter.

Former Starbucks CEO Howard Schultz also responded, replying with a winking emoji to someone who said, "I think this means Howard Schultz is the Three Eyed Raven?"

But at the end of the day, fans recognized that while the possible gaffe was fun, we still need to find out who ends up on the Iron Throne at the end of all this.

There are two episodes left in "Game of Thrones" and many players are still in contention to end up on top. We're gonna need a lot more caffeine to keep up with the twists and turns.
