First there was a coffee cup, now it's a bottle of water. Bad Thronespel just can't take a break.
A couple of weeks after some eye-catching fans discovered a forgotten coffee cup on a scene of a couple of misplaced water bottles have appeared. The bottles, seen in screenshots below, appear a few times for a few minutes. The first time is at 46:19 on HBO now and then a few minutes later. One is just behind Samwell Tarly's foot in the picture below.
Another water bottle can be seen just behind Ser Davo's chair, between him and Gendry.
It is understandable that long-term meetings about Westero's future would leave someone a little dehydrated but people clearly forgot to throw the bottles off once the director shouted "action!" Although it is not as sharp as the abandoned coffee cup, you can imagine Game of Thrones editing team that goes through the final with a fine comb. Thronespel is the most reviewed show on television. Its fans are known for finding these things, and they are already on this goof.
HBO responded to criticism last time it happened to joke with. "The latte that arose in the episode was a mistake," read a statement from HBO. "Daenery's had ordered a herbal tea." The company also went in to digitally remove the cup after dozens of articles and thousands of fans tweeted about it. Bernie Caulfield, an executive producer at Game of Thrones, pointed out in an NPR interview that these things are happening and adding "if it's the worst they find, then we're in good condition".  Oh, shadowing! Apparently the worst thing that people could discover was that Westero's most powerful gentlemen and ladies were not completely environmentally friendly and rely on bottles instead of tap water. Or maybe well-watered in view of the time period? Don't feel so bad, HBO – you're not the only one who has forgotten water bottles.
Verge has reached out to HBO about whether the water bottles will also be removed.
