After the last Season 7 video tease someone even analysed the reflections in the eye of a White Walker. If that isn't dedication then frankly we don't know what is.

The latest set of Season 7 photos are no exception. After the way things were left with Cersei and Jaime at the end of Season 6 there's plenty you could read into the image below of them side-by-side.

But there's one detail in particular we wanted to draw your attention to.

It's a bit blurry, but you can clearly make out the red jewel and the golden bands that circle the hilt.

And unless we're wildly mistaken, that isn't just any old sword -- we've seen it before:

That last screenshot is from Joffrey's wedding day in Season 4, and the sword is Widow's Wail -- the Valyrian forged blade he uses to hack up the book Tyrion gives him as a gift. According to its Wikipedia fandom page, that sword hasn't been seen since Joffrey's death.

So why is it significant?

Well by now HBO knows the extent to which we pick these promos apart. Surely no detail, however small, makes it into the promotional material by accident.

So here's what we've got: Jaime standing next to Cersei with a hard-to-fathom expression on his face, in possession of a blade which hasn't been seen for two seasons, which just so happens to be named "Widow's Wail".

An early clue that he'll be using that sword to bring about Cersei's demise? We'll have to wait and see...
