There are dozens, if not hundreds of fan theories related to Game of Thrones. After seven seasons and more than 60 hours of footage, people can't help but look into potential hidden meanings behind characters, locations and even inanimate objects.

 The latter is the focus of one of the latest theories from fans, but it's a stretch.

If you look at Jon's sword, Longclaw, it's eye changes colour just as he comes out of the icy depths. Some people on the internet are even saying the wolf is opening its eye. Basically, GoT fans across Twitter are certainly confused by the tiny detail.
