5. Daenerys' costume this episode could be a nod towards her softening stance on Jon Snow.
Is Daenerys being wooed by Jon Snow?
So far we've seen several new costumes for Daenerys on the seventh season – all of them evoking her Targaryen heritage and even hearkening back to her brother Viserys.
After speaking with costume designer Michele Clapton, we know that every detail of the costumes is meant to convey how the character is feeling or thinking, which is why we perked up when Daenerys was seen with a silvery-grey cape on this episode.
Prior to "Spoils of War," Daenerys has only worn red capes, the color of the Targaryen sigil. But grey is one of the colors of House Stark. Is this just another monotone costume choice? Or are we meant to understand that Daenerys and Jon's relationship is becoming friendlier?
6. Davos corrected Jon Snow's grammar in a great callback to Stannis Baratheon.
Jon and Davos spoke about Daenerys and the Night King.
While discussing Daenerys and her "good heart," Jon switched subjects to discuss strategy.
"How many men do we have in the north to fight [the Night King]? 10,000? Less?" Jon asked.
"Fewer," Davos replied.
"What?" Jon said.
This was a reference to one of many jokes the fandom makes about Stannis — his knack for correcting people incorrectly using the word "less" instead of "fewer."
Season 2, Episode 4: "Garden of Bones"
On the second season, Davos told Stannis he didn't mind that his king had chopped off most of his hand. "It's four less fingernails to clean," Davos said.
"Fewer," Stannis said, correcting him.
"What?" Davos replied.
"Four fewer fingernails to clean," Stannis said.
And Stannis gave the same grammar lesson again on the fifth season.
Season 5, Episode 5: "Kill the Boy"
When Stannis and Davos were sitting in on a Night's Watch meeting about letting the Wildlings south of the Wall, Bowen Marsh argued they should just die.
"Less enemies for us," Marsh said.
"Fewer," Stannis said under his breath.
"What?" Davos asked.
"Nothing," Stannis replied.
But based on the season seven episode, it looks like the lesson finally sunk in for Davos, who has become more and more literate as the series has gone on (mostly thanks to Shireen's teachings, R.I.P.). Now it's Jon's turn to learn the difference between "less" and "fewer."
