All the drinking party scenes were great.
Ghost!
Also the Jon, Sam, and Edd reunion.
I know Maisie's in her 20s now but I was still taken aback at Arya getting a nude scene.
Loved the Lyanna and Jorah interaction.
It's amazing to see how far the Stark kids have come. A Three-Eyed Raven, a Faceless Man, a resurrected king, and a mastermind Lady.
