Warning: Spoilers ahead for Sunday's episode of "Game of Thrones" season seven, including speculation of future events.
"Game of Thrones" season seven kicked off with an epic cold-open that surely had fans fist-pumping around the world. Between Arya's reverse-Red Wedding murders, Daenerys' arrival to Dragonstone, and more Tormund/Brienne eyebrow-raising, there were several significant moments you may not have caught.
Let's dive into the most important details you might have missed.
The Valyrian steel blade used in Bran's assassination attempt in season one cropped up 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 in 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.
So who has the blade in the show now?
In the books, Littlefinger took the blade from Ned Stark when he betrayed him. But in the show, it's a bit of a mystery — one that could involve Arya Stark. Odds are very high that Littlefinger has the blade on the show, too, but we can't be sure.
Ed Sheeran's cameo 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's 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.
