We weren't exactly huge fans of Ed Sheeran's much talked about Game of Thrones cameo this week because the Seven Kingdoms is just no place for him and it totally cracked into our suspension of disbelief with the show. Dragons? Yes. Raising the dead? Grand. Ed Sheeran? Get the boat.

His appearance on the show also featured him singing, which at the time just added to our irritation at the whole thing but the good old book readers have stepped in to point out that this was in fact no random song.

Ed was singing 'Hands of Gold' which features in the third Game of Thrones book, A Storm Of Swords, and is used by a character called Symon to blackmail Tyrion over his affair with Shae.

The lyrics go:

"He rode through the streets of the city,

Down from his hill on high,

O’er the wynds and the steps and the cobbles,

He rode to a woman’s sigh.

For she was his secret treasure,

She was his shame and his bliss.

And a chain and a keep are nothing,

Compared to a woman's kiss

For hands of gold are always cold,

But a woman’s hands are warm."

As we all know though, Tyrion and Shae's affair ended back in season 4, along with her death at the hands of her former lover, so the song could be pointing towards another Lannister brother's not-so-secret affair.

A Lannister with a hand of gold per chance?

Fans are guessing that the use of song could foreshadow Jaimie's eventual killing of his sister Cersei, which is a theory this writer also subscribes too. Cersei was told as a child that she would die at the hands of 'a younger sibling' and while Tyrion may be the obvious suspect there we can't help but think that king slaying Jaime may become a queen slayer as he watches his sister go further and further into her villainous ways.

Although saying that, the Ed Sheeran scene also saw Arya telling the Lannister soldiers that she was on her way to King's Landing to 'kill the queen' and not many have made it past the youngest Stark alive in recent seasons.

Cersei also has a hell of a lot of enemies now given her stunt last season but still.... there would be a certain poetic justice to her dying at the hands of her brother/lover.

At the very least, it would also give some purpose to Ed Sheeran's cameo.
