'Breaking Bad' writer talks last night's episode, 'Granite State' | Inside TV | EW.com
So yea, the Grey Matter story ain't dead.
Also, talking about the phone call, I feel like ever since last week’s phone call with Skyler, Walt has been almost trying to conjure up Heisenberg. And then in this episode, he starts to put on the hat and he can’t do it, and by the end you feel like he flips that switch, and you have Gretchen saying, “The Walt I knew is gone,” and having that parallel. What was it about Gretchen and Elliott’s interview that really set him off? She talked about the brilliant man being gone, but they also claimed he had nothing to do with their success.
There’s so much that goes on in that moment. There’s a lot of switches being closed, I think, in Walt. There’s emotions about the past, but then there’s also something else that we’re going to follow up on. A lot of that moment is going to be explored, what went on there. I’m trying to say enough without saying too much.
So yea, the Grey Matter story ain't dead.
