WARNING: Spoilers.
GAME of Thrones fans are convinced a huge secret is about to be revealed after eagle-eyed viewers spotted a hidden clue on Jon Snow’s sword.
The blink and you miss it moment came in the latest episode as the King of the North climbed out of the lake, The Sun reports.
Jon was battling White Walkers north of the wall and nearly died for a second time when he plunged into the icy waters.
Game of Thrones viewers breathed a sigh of relief when Jon was seen hauling himself out onto the ice and gasping for breath.
He used his sword to help pull himself out of the water, and many fans noticed something very strange about the handle, which is carved into the head of a dire wolf.
The carving seemed to open it eyes as Jon emerged from the lake, and fans are now convinced there is a hidden meaning to the scene.
Jon was rescued from the walking dead by his uncle Benjen, who sacrificed himself so his younger relative could get away on his horse.
He was later seen recovering in bed at The Wall with Daenerys Targaryen by his side as they prepare for next week’s grand finale.
Viewers flocked to Twitter at the end of last night’s show to discuss the sword theory, with many pointing out the carving seemed to come to life.

Another added: “Jon Snow sword is alive!?! Hw cm i dint realize this b4 #GoTS7e6.”
A third wrote: “Is it just me or did Jon Snow’s sword just blink? #WhatTheF***! #GoTS7.”

The episode previously featured a conversation between Jon and his travelling companion Ser Jorah Mormont about the sword in question.
The former member of the Night’s Watch revealed the sword, named Longclaw, actually belonged to Ser Jorah’s father Jeor Mormont, who served with him and gave it to him before he died.
Many fans insisted they would be rewatching the scene between the pair to mine it for crucial clues about the sword.
