I always have a sense of where I want to end each season, emotionally and relationship wise and with the theme, and I'm always able to hit that.

I started doing some more specific research on Wales in that period because I like the idea of being authentic to the territory, and with that came the knowledge that there was this great rebellion that was happening with the Marcher barons and conflict with the king. A lot of it wasn't documented by the English.

The whole Twitter phenomenon is really indicative of what's happening in this country. And I say this in condemnation of myself as much as anyone else - we are growing into a nation that has no time, desire or capacity for truth. All we can handle is 140 characters of knowledge.

I think there's a part of me that feels the need to hide a little bit behind a character.

I have a loose blueprint of where I want the show to go. I stress, quite frankly to remind myself, that I hold onto that vision very loosely, so that I can be moving towards something, but I don't ever want to feel like I'm in a box that'll stop me from exploring a potential new direction.

I've always wanted to play with this idea - and I didn't want to leave it to the last season, but I wasn't quite sure when it was going to happen - of putting Jax [sons of Anarchy] at the head of the table and the ripple effect on the guys and the loyalties of it and where people land.
