After that scene, my brother asked: "why is he trolling the girl?".
That's what it seemed to me, too, but it might have been the "Carcetti face" alone, to have that effect.
Also, i wonder how fast we're going, cause we are just in episode 4 and already every key character, knows that the Lannisters are pieces of shit, responsible for Bran's injury and allegedly Arryn's death.
I mean, it's already over? Again, i haven't read the books, so i don't know what's coming, but i thought this was a major plot point and they seem to have burned it out already, in 4 episodes?
Granted there's all the Dothraki conflict, but still.
It's not a complaint, mind you, just a concern.
