I could not remember this scene so I tried to find it, it is actually a conversation between Cersei and Robert where he explains the Dothraki problem. These type of scenes make me remember how great the first few books, and in extension, the first few seasons were.
Another thing I liked about this scene is that it proved everyone wrong about Robert -- too often character's opinions of other characters is really the Voice of The Writer, and 100% accurate.
Damn, what an episode. It is hard to remember anything past the final battle, but what I also really liked is all the Starks coming together. They all have had crazy lengthy and sometimes boring story arcs, but now that they are coming back together, each in their final badass form, I see that the arcs had their purpose.
Yeah,
Jon Snow: King in the North, uniter of Peoples, badass warrior, future dragonrider.
Bran Stark: Sees the future, the past and the present; can take over people and animals alike.
Arya Stark: Magical Assassin who can not only take out entire powerful families at once, she could kill the (evidently) best warrior in the series instantly if she wanted to, in straight combat.
Sansa Stark: Has mastered the resting bitch face.
