"You're Heisenberg."
"You're god damn right."
Before the start of this season, I read a really interesting interview with Bryan Cranston in which he was asked when he thought Walt 'broke bad' past the point of being redeemable to the audience.
I don't remember Cranston's response, but I do remember many examples of what that moment has been for fans.
Spoilers for the latest "Breaking Bad" under the cut.
