WARNING: This article contains spoilers from Game of Thrones season seven, episode six.
While most fans were recovering from the death of Daenerys Targaryen’s (played by Emilia Clarke) dragon Viserion, many were left baffled by this important blink and you’ll miss it moment.
Before Jon Snow (Kit Harington) fell into the depths of an icy lake, as he attempted to fight off the army of the dead, he dropped Longclaw to the side before sinking.
The camera then hovered at ice level with the sword in focus as those watching the hit HBO show anxiously waited for Jon to surface.
When the King of the North finally rose from the sub-zero water, the eyes of the direwolf on Longclaw appeared to pop open.
Did the sword which was given to Jon by Lord Jeer Mormont (James Cosmo) bring him back to life?
Eagle-eyed fans rushed to comment on the major moment as they debated what could have been the cause for the apparent movement.
One person wrote on Twitter: “Did anyone else notice that Longclaw’s eyes opened when Jon emerged from the water? Does that mean he died again & came back? #GameOfThrones.”
“How the f**k Longclaw opens its eyes?! The same thing happened when Jon was resurrected in s6 wtf is this #GameofThrones #gots7,” said another eagle-eyed fan.
“So Jon’s Sword Longclaw open its eyes, I’m mind blow,” said one person, while a third was equally as gobsmacked: “Seriously, that Longclaw thing is GENIUS!!! I can’t believe I didn’t notice that. #GoT.”
One fan thought Bran Stark had warged himself into the direworlf as the pommel of the sword is thought to be made out of weirwood, a species of tree which the Children of the Forest carved their faces on.
They wrote: “As Jon pulls himself out of the lake, longclaw’s eyes open, as if possessed by Bran. So the three eyed raven sent for Benjen again #GoTS7e6.”
Game of Thrones continues on HBO this Sunday in the US and will be simulcast on Sky Atlantic on Monday at 2am.
