Palesun:
I guess everyone sees what they want to see or have different interpretations of what they've read and seen but I've read that TH was one of the screenwriters and I know there're a lot of conversations bts with the actors and directors and screenwriters about the characters and their emotions etc to be able to portray the characters authentically so I thought if anyone would know the characters best other than the author, it would be the actors who were playing them. But some of those things they've said are so diametrically opposite to what I'm seeing and reading in the drama and book respectively that I'm beginning to wonder.
Thank you for your long post :). As I'm mostly a visual person, I, if possible use the less words possible :p So, excuse me if my answer seem too short...
As you said, you've read this that interviews etc...
I'll stick mainly, as we are talking about her collaborating to the scripts of the drama, so that it remain faitfull to her creation - I'll stick to this interview. All others comes after.
So I have a light lamp to the whole plot, characters arcs, backgrounds, settings and ending. The rest...is from my pov overflow and as such can confuse :).
