1. During Daenerys' strategy sessions, the title "Queen of the Ashes" was used twice.
Tyrion (Peter Dinklage) wants Daenerys (Emilia Clarke) to rule with compassion.
When the tactic of having Daenerys' dragons wreak havoc on King's Landing was suggested, Tyrion was quick to tell Dany that the last thing she wanted was to burn the whole city to the ground.
This was a callback to Varys' warning to Olenna about Littlefinger.
Varys (Conleth Hill) knew how dangerous Littlefinger can be.
On season three, episode four, Varys and Olenna had a secretive conversation about where their loyalties lie. Varys warned Olenna not to trust Littlefinger.
"He would see this country burn if he could be King of the Ashes," Varys said.
Clearly everyone is steering Daenerys as far away from the other game-players as possible, including the "chaos is a ladder" archetype of Littlefinger.
2. Where The Wall Meets The Sea
Last week, we got a glimpse of the Night King and his ever-expanding army of the dead, thanks to Bran's super convenient visions. But this particular vision has been the source of much debate. For instance, is that wight giant really Wun Wun? And where exactly is the army supposed to be? Some assume that they're North of the Wall, walking southward; others speculate that it looked like green grass turning to frost beneath the Night King's storm; and some fans suggested that it didn't look like solid ground at all, but frozen water beneath the army's wintry feet. Now, one extra watchful redditor, RohitMSasi, spotted something in the opening credits that might settle that debate once and for all.
The Wall runs across the stretch of land between the Far North and the regular North. Back in Season 1, the Wall was stopped by water on both sides. Now, Winter has come, and you can already see that the sea is freezing over on the sides of the Wall. Forget about needing to tear the Wall down — the Night King and his army can simply go around it. This is exactly what the Hound predicted would happen in his fiery vision from the last episode:
"Ice, a wall of ice. The Wall... It's where the Wall meets the sea. There's a castle there... There's a mountain, looks like an arrowhead. The dead are marching past, thousands of them."
3. Daenerys thought Jon Snow sounds impressive and described in a way that mimicked Sam Tarly's thoughts on her.
Daenerys heard about Jon Snow for the first time in "Stormborn."
Melisandre told Daenerys about Jon's accomplishments and why he could be a prophesied hero (read our full explanation of the significance of the prophecy to learn more).
"As Lord Commander of the Night's Watch, he allowed the Wildlings south of the wall to protect them from great danger," Melisandre said. "As King in the North, he has united those Wildlings with the Northern houses so together they may face their common enemy."
"He sounds like quite a man," Daenerys replied.
That's almost word-for-word what Sam Tarly told Aemon on season five.
Maester Aemon was Daenerys' uncle.
On the fifth season, Sam read a letter to Maester Aemon.
"And though Daenerys Targaryen maintains her grip on Slaver's Bay, forces rise against her from within and without," the letter said. "She refuses to leave until the freedom of the former slaves is secure."
"She sounds like quite a woman," Sam said. Clearly the show is trying to draw as many parallels as possible between the Mother of Dragons and the King in the North. (Shout out to @AdelaidaFall for spotting this connection.)
4. Sansa Is Cersei And Arya Is The Hound
Last week, we marveled at how Sansa has started styling her hair á la Cersei Season 1 and is emulating her manipulative ways. It makes sense, given that Cersei was basically responsible for Sansa's stilted upbringing for most of her adolescence. Much like how Sansa grew up under Cersei's wicked wing, Arya spent a formative year with Sandor "The Hound" Clegane, learning to be a brutal killer and to expect the absolute worst from people. You can see the Hound reflected clearly in the way Arya greedily and rudely snatches food from Hot Pie's tray, unable to muster any sort of emotion for her old companion — that is, of course, until he cracks her cynical exterior with the news that the Starks have retaken Winterfell and Jon Snow is King in the North. Before that point, Arya was pure Hound: expressionless, ornery, selfish. But thankfully, it doesn't look like she'll be stuck that way forever.
