She has had several meager sources of income: writing short stories, selling items on eBay, working as a bookkeeper, and ultimately helping her husband launder money. Skyler White ( née Lambert) (played by Anna Gunn) is Walter's wife. Walt's descent, Macbeth-like, into the criminal underworld unearths immense levels of deeply repressed ambition, rage, resentment, vanity, and an increasing ruthlessness which alienates him from his family and colleagues. He also comes to find his new status as a drug lord psychologically rewarding, leading him to become increasingly willing to resort to criminal acts such as theft, extortion, money laundering, depraved indifference, and murder. Walt is initially squeamish about the use of violence, but gradually comes to see it as a necessity.

His crystal meth, which is given the street name 'Blue Sky', dominates the market, leading to confrontations with established drug makers and dealers. To avoid the tedious collection of pseudoephedrine required for production, Walt devises an alternative chemical process utilizing methylamine, giving his product a distinctive blue color. Walt's scientific knowledge and dedication to quality leads him to produce crystal meth that is purer and more potent than any competitors'. Knowing nothing about the drug trade, he enlists the aid of his former student, Jesse Pinkman, to sell the meth he produces. After being diagnosed with lung cancer, he starts manufacturing methamphetamine to provide for his family upon his death. Walter Hartwell White (also known by his clandestine alias Heisenberg) (played by Bryan Cranston) is an overqualified high school chemistry teacher from Albuquerque, New Mexico.
