What's Alan Watching?: Breaking Bad: Vince Gilligan post-mortems season two:
The character continues to surprise us, the writers, in the writer's room. 'What would he do now?' 'I think he would do this.' 'Maybe he should do this instead.' It's a little hard to believe for folks who don't spend every waking moment in the writer's room plotting out a fictional character's life mm that sounds like a fun job, but they do kind of come to life for us. They become, in a sense, separate from us. They demand certain moments and bits of behavior that we, in a sense, don't want to give them. It sounds a little precious to put it that way, but they do. If we're going to be honest about a guy who sets out to be a criminal, we have to see where it takes itself.
he conceit that he's doing this all for his family, has gone by the wayside quite a long time ago. To me, that's what's interesting about the show, and makes me get out of bed every morning, enthused to be a part of it, is we're not leaving this character static. We're changing him in increments, sometimes small, sometimes large, and we don't know exactly where he's going to end up.
"Go big or go home." That was our ethos for last season: go big or go home. We figured in for a penny, in for a pound. We've come this far, let's be honest about it.

--In the finale, Skyler finally puts enough of what Walt is doing together to want him out of her life. But what's she telling Flynn about why his dad can't live at home anymore? yeah Flynn who's just made his "Save Walt White" website & been profiled in the newspaper talking about how his dad is so decent, always does the right thing, is his hero.
Good question, and that's been a big focus of conversation in the writers room here in season three. I can't tell you too much. It's stuff you'll see in the first episode, but I can give you this: I don't think she's telling folks too much. You're asking the right question, let me put it that way. When a woman is going to leave her husband, everybody needs to hear a reason. What reason do you give if the reason you're leaving is that you don't know what he's involved in, and you don't want to know.

-An absolutely riveting and visually stunning final episode that rivaled the best that TV has ever offered.
