The water bottle, which can be seen in the image below, was seemingly found by Twitter user @bethisloco and was soon spotted by several others. It appears in a brief shot as Tyrion is taken in shackles to the remaining heads of the great houses to decide his fate. The water bottle can be seen peeking out just behind Samwell Tarly’s leg while he's sitting down.A similar production oversight occurred in 'The Last of the Starks’ where a disposable coffee cup could be found in front of Daenerys in a brief shot. The cup was later digitally removed from subsequent airings of the episode - it’s likely this water bottle will meet the same fate.For more on the series finale of Game of Thrones, read about its most meta moment , what Kit Harington and Emilia Clarke had to say about Daenerys’ fate , and who the surviving heads of the great houses are In our 'The Iron Throne' review , we called the episode “Good” calling it "A bittersweet if underwhelming climax to a show that's been a true cultural obsession."
