Warning: spoilers for Game of Thrones season eight, episode two "A Knight of the Seven Kingdoms" follow.

As the army of the dead close in on Winterfell, the fate of nearly every Game of Thrones character grows increasingly precarious. And while we all watched this weekend's "A Knight of the Seven Kingdoms" with an eagle eye for any clue about what is to come, one moment stood out, and it could hint at what's in store for Daenerys Targaryen and Jon Snow.

As a group including Jaime Lannister, Tyrion Lannister, Brienne of Tarth, Davos Seaworth, and Tormund Giantsbane settle for a pre-battle drink before a fire, humble Podrick responds to a call for a song. Unpacking the message in the song largely depends on whether you've read George R. R. Martin's books and how well you remember the convoluted (and inbred) web that is the Targaryen family tree. But before we get to all of that, here are the words:

High in the halls of the kings who are gone Jenny would dance with her ghosts The ones she had lost and the ones she had found And the ones who had loved her the most The ones who’d been gone for so very long She couldn’t remember their names They spun her around on the damp, cold stone Spun away her sorrow and pain And she never wanted to leave…

Listen to Podrick's song below:

The first two lines Thrones fans will recognize from the novels (more lyrics were added for the episode). The song is about a character called Jenny of Oldstones, who married Duncan Targaryen.

Duncan isn't really mentioned in the show (mostly because the Targaryen line is confusing enough), but in the books, he was in line for the Iron Throne but renounced his claim by marrying peasant Jenny of Oldstones rather than going along with the marriage to a daughter of Lyonel Baratheon his parents had arranged. Later, Duncan died in a fire in the Targaryen castle of Summerhall. He is likely one of the ghosts Jenny dances with in the song.

If we're to tap into fan theories, the lyrics could foreshadow what's in store for Dany and Jon as the end of Game of Thrones draws near. As we now know, Jon is the last male Targaryen heir, Aegon Targaryen, and technically in line for the Iron Throne. But Jon has never shown much lust for power, while Daenerys has had her heart set on the Iron Throne for years. She certainly didn't look pleased to find out this week that her new lover is both a relative and direct rival for the throne.

Could it be that Jon steps aside and gives up his blood right — as Duncan did for Jenny — and leaves Dany free to reign? If they survive the White Walkers and defeat Cersei Lannister, that is.

Should that be the case, it could mean that Daenerys is left ruling a new version of the Seven Kingdoms — but potentially dancing in the Great Hall with only the ghosts of everyone she loves — Jon, Tyrion, Greyworm, Jorah Mormont et al — for company.
