'Game of Thrones' fans think Jon has some explaining to do about those cave drawings

Warning: This article contains major spoilers. If you don't want to know what happened in last night's episode, then white walk away!

Since his arrival at Dragonstone, Jon Snow has been petitioning Daenerys for her help in the impending battle against the White Walkers. The queen has everything the North needs to have a fighting chance -- the army, the dragonglass, three fire-breathing dragons. The problem is that Dany and her council aren't convinced that the legend of the White Walkers is real.

During last night's episode, Jon showed Dany something that shook the queen and changed her mind about the army of the dead. Deep inside the dark caverns beneath Dragonstone were walls covered in pre-historic drawings of the First Men and the Children of the Forest fighting as one against their common enemy -- the White Walkers.

While Dany seemed convinced of the legitimacy of the ancient drawings -- pledging her support to the North if Jon bended the knee -- some fans weren't buying it.

One redditor called BrySighz dropped this hilarious illustration into the /r/GameofThrones subreddit with the caption: "This immediately popped in to my head after the cave scene so I drew it."

It's obviously a joke, but perhaps there's something to this comical fan theory. After all, Jon and Ser Davos were the only two people at the caves when Daenerys arrived on scene. And it's pretty convenient that Jon happened to stumble upon these cave paintings that proved that the White Walkers were a threat.

Suspicious. Very suspicious.
