HBO

Warning: Spoilers ahead for the "Game of Thrones" season seven finale: "The Dragon and the Wolf."

The seventh season of "Game of Thrones" came to a devastating close Sunday night with the long-predicted destruction of the Wall. But before fans were treated to the epic blue flames of an undead dragon, there were several small but significant moments tucked throughout the episode. 

Keep reading for a look at the nine details you might have overlooked in the season seven finale.

While trying to win Cersei's trust, Jon Snow warned her that the real enemy wouldn't negotiate.

While speaking of the Night King and his army, Jon assured Cersei that they were dealing with "a general you can't negotiate with."

He meant that literally. According to the "Game of Thrones" showrunners, the Night King will never speak.

After the season six finale, David Benioff and D.B. Weiss said the Night King wouldn't have any lines on the show.

"We don't think of the Night King as a villain as much as Death [...] In some ways, it's appropriate he doesn't speak," Benioff and Weiss told Deadline in 2016. "What's Death going to say? Anything would diminish him. He's just a force of destruction. I don't think we've ever been tempted to write dialogue for the Night King. Anything he said would be anticlimactic."

Later in the dragonpit, Daenerys said a phrase in High Valyrian we last heard on season three.

"A dragon is not a slave," Daenerys told Jon, first in High Valyrian and then again in the Common Tongue.

This was part of the epic moment when Daenerys bought the Unsullied in Astapor, back on the third season.
