NEW YORK —
"Why are you here?" she asked him coldly.
"It's over," he said, "and I needed a proper goodbye."
After all this time, he justified out loud his descent from life as a meek, ill-paid chemistry teacher to a life as a legendary drug lord. Before, he had always insisted he did it for his family, to leave them provided for after his death from his terminal cancer.
"I did it for me," he declared to Skyler. "I liked it. I was good at it. And I was alive."
Walt's former meth-cooking sidekick, Jesse Pinkman (Aaron Paul), was still enslaved to a group of bad guys forcing him to cook crystal-meth for them using the laboratory-pristine process Walt had pioneered and prospered with. Walt rescued Jesse: His assault rifle mowed down the bad guys by remote control from the trunk of his car.
Freed, Jesse was last seen speeding off, screaming in hysteria, rage and gratitude. Against all odds, he had lived to face another day.
For Walt, the outcome was much different. As the cops descended at the scene of the mass slaughter to seize him, he was lying on the floor, dead, apparently from a stray bullet from his own rifle. An inadvertent suicide, he had successfully escaped from the law, his foes and the cancer that was stalking him.
And, yes, Walt used the ricin he had held in reserve for ages. He poisoned Lydia Rodarte-Quayle, who had shown the bad judgment to collude with Walt's enemies on more than one occasion. He substituted it for the sweetener she thought she was putting in her tea.
The episode, and series, ended with Badfinger's "Baby Blue" ("Guess I got what I deserve").
