Season 8, episode 2 of Game of Thrones, "A Knight of the Seven Kingdoms," had its fair share of moments that could have given away hints for episodes to come, like in the writers' decision to include "Jenny's Song," or in Jon Snow telling Daenerys Targaryen that they're related.

One fan theory about the fate of Westeros, however, comes from the previews for next week's episode. Posted by Reddit user IgnorantSportsFan, the theory centers around one pivotal line uttered during a conversation between Daenerys and Jon: "The dead are already here."

"That line happens between Dany and Jon, and felt super significant—but we already see the army of the dead, felt it was too obvious to be their reaction to them," the theory begins."Then it clicked: The crypt is full of dead people. All episode they keep repeating and emphasizing how safe it was in the crypt, but its GOT and we cannot have nice things. So is it possible we have old Starks rising from the crypts? Or is that too far fetched?"

The theory certainly adds up, emphasized by the reminder that there were clips included of Arya Stark fighting in the crypts.

Could the dead be rising in the crypts of Winterfell as the White Walkers rapidly approach? We'll find out soon.
