Pitch and Sandy have a Yin and Yang relationship. Notice how Pitch has golden eyes? The golden eyes represent his goodness. Sandy can turn to evil very easily, that is his darkness. The fact he can turn evil easily.
'Breaking Bad's' Walter White is a remarkable character on television. Y'all can have Tony Soprano or Don Draper. I'll take Walter 'Heisenberg' White any day! Kudos to Bryan Cranston for playing the hell outta this role!
