Tell them, the North remembers......
Great line by Arya
They are setting up very interesting possibilities as Samwell Tarley finds out there’s a whole bunch of dragon glass at dragonstone and Jon mentions that they need to get a lot of dragon glass to fight the white walkers, and now who is at dragonstone? Is this how Jon and Danerys meet? I would think he would send Davos down there as an emissary.
We also find out (through Sam’s montage) that Ser Jorah (the one with the Grayscale) is now in the quarantine cells at the Citadel. Guess the rumors of the actor Jim Broadbent being cast as a Grand Maester in order to “cure” Jorah’s grayscale are panning out.
Tyrion is a natural connection. “You’re the Lord brother of my wife Sansa. How are you, and how is she?”
If I have been following things correctly, and I may not be, Jon and Danerys do meet and each considers the other a good match, only to find out at an inoportune time that they are half brother and sister.
