Zealous Game of Thrones fans will know that, unlike in the show, music and songs play a very important role in the books by author George R.R. Martin.
The scene in question happened while several characters - many of them knights - gathered in a hall on the eve of the battle for Winterfell. "The Prince of Dragonflies [Duncan] loved Jenny of Oldstones so much he cast aide a crown, and Westeros paid the bride price in corpses".
If you had to compile a list of pop artists to sing the end credits theme for your show about medieval murder and dragons, Florence And The Machine would be right at the top - which is why it's actually kinda weird that it took eight seasons for the powerhouse act to guest on an episode of Game of Thrones.
How is the song used in the books?Their union, which Prince Duncan's father King Aegon V Targaryen disapproved of, spurred Prince Duncan, who had been engaged to a daughter of Lyonel Baratheon, to renounce his claim to the Iron Throne despite being the rightful heir. If Dany is the one destined to defeat the White Walkers and usher in a new spring, the best thing Jon can do is love and convince others to do the same.
The final season of Game of Thrones continues next Sunday night on HBO.
There is a good chance that Jon wants nothing to do with the Iron Throne - he was already hesitant to be named King of the North - and lets Daenerys rule Westeros. But Duncan and Jenny's story doesn't end with a happily ever after. In the A Song of Ice and Fire books, this tune is titled "Jenny's Song", and is directly connected to the series' central characters and their ancestors. If the song is foreshadowing, then Jon will also give up the throne only to be killed in battle.
The reference to Jenny's "ghost" and how she "never wanted to leave" also seems to strike a chord with the looming threat of death.
The Importance of Jenny's Story While "Jenny of Oldstones" makes for flawless accompaniment as this episode closes out and we see the last defenders of Westeros preparing for their greatest battle, it has some deeper implications for two characters in particular. The Night King and his forces will likely destroy the majority of Daenerys and Jon's forces, and they will be lucky to get out of the fight in one piece.
