Jon Snow is putting his feminism to work, and I'm not mad about it. He's drafting Northern girls to his army as well as men and boys. He's taking council from his cousin (!!!) Sansa, even though he'd prefer their meetings to be private. His other mission, the search for the substance that kills White Walkers, is likely what will bring him together with a host of Westeros' most powerful women. Now that Sam learned that there's an underground mountain of dragonglass on Game of Thrones in Dragonstone, where Daenerys just landed, what does that mean for her and Jon Snow? This revelation could lead to war, but it could also lead to the partnership we've all been waiting for since the beginning of the series.
Well, this huge revelation isn't that much of a shocker. Stannis "the Mannis" Baratheon told Sam about the underground cache of precious materials in Season 5, and this research confirms it. Dragonglass is basically just magical obsidian, a volcanic rock. In the books, Stannis sends a Southern bastard named Rolland Storm to mine it, but his quest is not exactly successful.
In Season 6, Bran's vision confirmed that not only does dragonglass kill White Walkers, it creates White Walkers. So the Mother of Dragons finally crossed the Narrow Sea to come home and she's sitting on a valuable resource.
How will Jon respond to this news, presuming that Sam's raven makes it to him in the next episode? Will he try and take Dragonstone for House Stark? Based on his refusal to remove the Karstarks and the Umbers from their ancestral homes, I doubt that would be his strategy. It's more likely that he will try and appeal to Daenerys as a fellow ruler, explain the White Walker threat, and try to form an alliance.
Personally, I would love it if Sansa went to Dragonstone to speak with Daenerys. It seems inevitable that Dany and Jon will meet at some point, and this would would be an interesting meeting of the minds. Sansa would make an excellent addition to that squad full of goals, and it would mean reuniting with her first husband, Tyrion Lannister. They should catch up, I think.
Unfortunately, I think the brewing war might prevent that. The other members of House Lannister are mounting an attack, and Daenerys will likely be preoccupied with leading her many armies and trying to take King's Landing.
At least this will force Jon Snow to consider Cersei Lannister and the South. I don't agree with all of Sansa's political opinions, but she is right about her former "mentor" in King's Landing. The Night King may be moving towards the wall with his army of the dead, but Queen Cersei is just as much of an immediate threat. The fact that they need to involve her enemies to defeat the other enemy is a nice little ironic twist.
With dragonglass under Dragonstone and wildfire under King's Landing, I wonder what other underground treasures can be found on Game of Thrones?Plus, all of a sudden there are a lot of "dragon" things to keep track of this season. There's Dragonstone, the seat of House Targaryen. Dragonglass is beneath the stone. Then Greyscale, the dragon-y disease that has claimed a bit more of Jorah Mormont's arm than the last time we saw him. Not to mention Dany's three huge, thriving dragons.
That's fitting, I suppose, because House Targaryen is finally back in Westeros and ready to do business — or ready to do war, whichever comes first. If dragonglass is what brings these long lost Targaryens together at last, so be it!
