Last night's episode of the final season of Game of Thrones, "A Knight of the Seven Kingdoms," had a lot going on—from Brienne of Tarth becoming a knight to Arya and Gendry getting it on. However, one moment that stuck out for many fans was the song Pod sang as he, Brienne, Davos, Jaime, Tormund, and Tyrion sat around the fire. "Jenny's Song," may have been more than just a pretty tune: According to Vox, it may have foreshadowed the end of Jon Snow and Daenerys Targaryen.

The song comes from George R. R. Martin's books (though the show added some lyrics), and according to the theory, the lyrics are meaningful:

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.

The song is about a woman, Jenny of Oldstones, and Duncan Targaryen, a prince who gave up the Iron Throne for love—and later died in a fire at a Targaryen castle called Summerhall. According to Vox, the song could parallel what might happen between Jon and Dany: One of them may give up their claim to the throne for love—but even then, there might not be a happy ending in store. (And based on Dany's reaction to finding out that Jon is her nephew—and the rightful heir to the Iron Throne—a happy ending does not seem likely.)

Most things that happen on Game of Thrones have meaning, so we'll be waiting to see if the song plays a significant role in the rest of the season.
