On the season premiere, the Valyrian steel blade used in Bran's assassination attempt was shown in one of Sam's stolen Citadel books.
Sam stole several books from the Citadel library's restricted section. And while he was flipping through the pages, we got a peek at a drawing of a very important weapon.
The dagger is often referred to as the "catspaw blade"— a reference to the would-be killer (or catspaw) who tried to kill Bran on season one. We knew the blade was made from Valyrian steel and had a hilt made of "dragonbone," but its origins have been a big mystery in the books and the show.
Based on Sam's book, it looks like we now know the blade is an ancient Targaryen weapon.
We later saw Littlefinger give the dagger to Bran, who in turn gifted it to Arya.
If you rewatch the moment when Bran gives Arya the dagger, it almost looks like he knows she will do something important with it — like kill Littlefinger.
The actor who plays Bran, Isaac Hempstead Wright, told INSIDER he meant to hint at the blade's significance in that scene.
"Whether he knows that exactly or not, I think he looks at it and can see this that this dagger has a purpose, it has a fate, it has a destiny," Hempstead Wright said. "And that destiny is to kill Littlefinger [...] And that's why he gives it to Arya so suddenly. He's thinking, 'I don't know why, but you need this dagger.'"

Ed Sheeran's cameo on the premiere featured more than just a lovely song — the ballad had a huge significance in the book series.
In the books, Tyrion keeps his lover Shae in a house in King's Landing (not inside the Red Keep as Sansa's handmaid). This meant Tyrion would travel from the keep to her manse. A singer named Symon Silver Tongue befriended Shae and tried to blackmail Tyrion into helping him sing at the royal wedding — or else he'd sing a song about Tyrion and Shae for all the world to hear.
Here are the song lyrics, written about Tyrion and Shae:
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 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
