Does this Easter egg from GoT S7's new images hold the key to Cersei's future?

Game of Thrones, our favourite medieval-themed TV show by HBO, continues to tease its fans as Season 7 inches up closer to its release, and this time, it's with some new pictures.

What do fans do at such times? They speculate. And speculate they did.

It's in one of these 15 pictures though. Check them out and see what we have to say about it!

Yep, it's this one!

Look closely!

Aha! There it is. The Widow's Wail.

You may ask what that is?

Don't you know? Septa Unella is coming for you with her chants of "Shame, shame, shame...!"

Well, it's the sword of ex-king Joffery, last seen when he stabbed a book given to him by his uncle Tyrion.

Courtesy of the eagle-eyed, GoT loyalist xpbso's Reddit thread where the clue was first pointed out, the sword's hilt – albeit a bit blurry when zoomed in – can be seen studded with the red jewel sitting inside the golden bands.

Now what to make of this? Jaime stands staring thoughtfully at something beyond the camera's eye, next to Queen Cersei, who is, as usual, wearing her signature 'how-should-I-gain-from-this-situation' look. And he happens to be equipped with a sword no one has seen in the prior two seasons.

Fishy!

Is this a foreboding sign? Is it a hint to how Cersei will meet her end? Or is it something that will be used against Jaime himself? Guess we gotta wait till July 16.
