32 important details even dedicated fans missed during 'Game of Thrones' season 6

HBO

WARNING: Spoilers ahead for "Game of Thrones" season six. 

The sixth season of "Game of Thrones" came to an end on June 26, but fans are still buzzing about the tumultuous final episodes. Throughout the season, we posted a running analysis of each episode, detailing smaller items and callbacks to previous scenes that the average viewer might have missed. 

Now we've gathered the 32 most significant of these details into one mega-thread. Scroll down for a look back at the most important scenes, costume changes, and book references littered throughout season six.

In the premiere episode, Brienne's vow to Sansa was word-for-word the speech she once gave Catelyn Stark.

If the oaths exchanged between Sansa and Brienne sounded familiar, that's because it is the exact promise Brienne made to Sansa's mother in season two. The emotional response both Brienne and Sansa had to this solemn vow was heartbreaking to watch.

Without hesitation, Brienne lowered her sword and swore a vow to Sansa. "Lady Sansa, I offer my services once again," she said. "I will shield your back, and keep your counsel, and give my life for yours if need be. I swear it by the old gods and the new." 

Brienne has wanted nothing more than to fulfill her promise to Catelyn of finding and protecting her daughters. Both Arya and Sansa eluded her grasp for a long time, but now she is in her rightful place. 

Melisandre isn't just a secretly old lady — she's "centuries old."

In HBO's "Inside the Episode" segment that aired right after the credits for "The Red Woman," showrunner David Benioff spoke about Melisandre. "There have been a few hints before that Melisandre is much older than she appears," he said. "[This is] going back to a very early conversation with George R.R. Martin about her: she’s supposed to be several centuries old."

In episode two, Bran's flashback showed a direct parallel between Jon Snow and Ned Stark.

During Bran's first flashback to Winterfell, he watched as a young Ned Stark sparred with his brother Benjen. Encouraging his little bro to fix his form, Ned says, "Get your shield up, or I'll ring your head like a bell."

Guess where you've heard that line before?
