“Game of Thrones” let a coffee cup slip into a shot earlier this season, and now, the series finale also has an anachronism. There is a plastic water bottle in one of the most important scenes of the final episode.

The moment appears at the 46:19 mark on HBO Go. It’s easy to miss, but eagle-eyed viewers who had their brightness turned up caught it quickly. Next to Samwell Tarly’s (John Bradley) left foot is clearly a modern-day plastic water bottle.

It’s a crucial scene in the “Game of Thrones” series finale. The lords and ladies of Westeros have gathered to figure out the future. With Daenerys Targaryen (Emilia Clarke) dead, and true heir Jon Snow (Kit Harington) responsible for her death, the council had to decide who will be crowned their next ruler. Eventually, Bran Stark (Isaac Hempstead Wright) was chosen as the king of Westeros while Sansa Stark (Sophie Turner) made the North an independent kingdom again.

Fans were quick to respond with jokes about the final “Game of Thrones” blooper.

Just two weeks ago, “Game of Thrones” accidentally showed a coffee cup in a scene. Dany was sitting at a table during a celebratory feast and among the goblets and medieval table dressings was a disposable coffee cup.

HBO responded to the situation by releasing a statement. “The latte that appeared in the episode was a mistake. Daenerys had ordered an herbal tea,” the network joked.

The coffee cup was digitally removed in less than 48 hours. The network will likely do the same for the series finale water bottle.

Fans will get to see plenty of coffee cups and plastic water bottles as well as quite a few other anachronisms when the “Game of Thrones” documentary airs next week. The HBO special will chronicle how the six-episode final season was made and will give viewers a behind-the-scenes look at table reads, actors’ last days and more. “Game of Thrones: The Last Watch” airs Sunday at 9 p.m. EDT on HBO.
