1x05: Gray Matter
"One of our finest moments was not necessarily one of our most dramatic. But in the writers’ room during the first season, we did an episode – only our fifth episode – where we offered a Deus Ex Machina moment to Walter White. We basically had a saviour, a white knight, come to Walter White in the form of Elliott Schwartz, his former friend and lab partner who is now a millionaire, running an enormous scientific research company."
"And Elliott comes to Walt and says, ‘I’ve heard about your cancer, I’m going to pay for your medical treatment, I’m going to pay the full freight on it, and I’m going to give you a job, anything you want – I just want to do right by you and help you and help your family…’ And instead of taking this life preserver that’s been thrown to him, Walt decides to go back to cooking crystal meth, and that’s one of my favourite moments and one of the most important moments in the life of the show, because prior to that I don’t think the writers and I truly understood Walter White."
"We didn’t understand that he was a creature of such pride and such damaged ego that he would rather be his own man and endanger his family’s life than take a handout like that. He’s that kind of a guy. Prior to that Walter White was basically a good but mislead guy with bad decision-making skills. He was going to make money, and then what was going to happen to keep him cooking meth? The money was going to get stolen, so he’d have to cook more meth… we came to realise truly what we had in that fifth episode."
"That’s when he broke bad, in a way. When the show kicked in to high gear, or started to, anyway."
