This episode is a little slower and quieter than most this season, and this fits the storyline perfectly. It’s a great place to pause in, almost an uncomfortable place. Limbo. Walter White has gotten this borderline miraculous news–he’s in remission and going to live for the time being against all odds–but isn’t feeling the relief and exaltation that he should.
I think it’s a few things. One, as discussed in the post for the previous episode, he’s felt that remorse in the desert for all his deception and lies and now he has to live with it. But I think it goes beyond that. He’s created this whole new identity for himself as Heisenberg. He thinks of himself as this total badass, even though this view of himself is a bit inflated. Sure, he’s tough when calling the shots on territory and revenge on the Spooges and raising the product price, but it’s all behind the scenes. Still, he has this new picture of himself as this criminal mastermind, not to be messed with. And I think he doesn’t want to let that go.
