So a married, middle-aged, high school chemistry teacher with a disabled teen son and infant daughter on the way is already floundering financially when he finds out he’s got cancer…what does he do? Start a meth business with a drug-addicted former student of his to ultimately become an international drug kingpin, of course. Fascinating character arch, but who on Earth would do such a thing? What kind of man would go from mild-mannered to cold-blooded in the course of about a year? A man like Walter White, apparently, which brings us to the question…what kind of man IS Walter White?
