Breaking Bad review: season five, episode 15, Granite State Walt spent most of the time confined to a snowbound mountain hut in remote New Hampshire (local motto: "Live free or die"), the Granite State after which this episode was named. Delivered there for his own good by the Extractor (Robert Forster), with his barrel full of dollars and a new identity, "Mr Lambert," he was warned to stay put in order to survive: "If you leave this place, you will get caught." Early on, we saw a restless Walt put on the Heisenberg hat and stride purposefully away from his hideout, only to hesitate at the gate and, defeated by doubt, mutter Macbeth-like, "Tomorrow, tomorrow...." As our initial glimpse of Walt was on a screen, captured on CCTV in the basement of the Extractor's office (a professional nowhere, wryly signed "Best quality vacuum"), so too was our first sight of Jesse (Aaron Paul). Having stolen from Hank's house the master copy of his filmed confession, Uncle Jack and his gang watched it on a giant screen in their living room, while Jesse lay chained in a pit outside. The proud smile that flicked across Todd's lips when the on-screen Jesse identified him as the killer of Drew Sharp was one of many moments - along with the faux-solicitous hand on Skyler's shoulder as he threatened baby Holly; and his cold-blooded execution of Andrea in front of a grief-addled Jesse - that further blackened Todd's image and gave ballast to those of us who like to cling to the belief that however bad Walt may be, there is a whole other category of evil into which he does not fall. Exactly who is Walter White, this high school chemistry teacher turned methamphetamine kingpin, remains the question at the heart of Breaking Bad. He is, by now, firmly engaged in the business of carving his own epitaph - "It can't all be for nothing," he bellowed down the phone to Walter Jr - but what name will the gravestone bear: White or Heisenberg, or indeed Lambert? "You're you," the Extractor said to him, when trying to explain why he had suspended his usual professional habit of disengagement for Walt. But even as he said it, the identity of the man he was speaking to seemed to wobble out of focus. Walt wasn't the only one seen trying to escape his identity. Saul was packed off to Nebraska, thinking to reinvent himself as the manager of a chain bakery; Skyler, we heard, had reverted to her maiden name and taken up taxi-driving; and Walt Jr, summoned to the school office to take a telephone call that turned out to be from his father, has once again chosen to cast off his father's Christian name and be called, instead, "Flynn White." That phone call, made from a bar down the road from Walt's hut was, like the high-voltage call from Walt to Skyler that had concluded the previous episode, the dramatic apex of this one, a gruelling, desperation-drenched attempt by a father to redeem himself in his son's eyes. "I wanted to give you so much more, but this is all I could do," he said, trying to explain why he was sending home a box-full of money. "You killed Uncle Hank," raged Flynn. Why are you still alive? Just die. Apparently defeated, Walt followed up that conversation with a call to the police to inform them of his whereabouts, then sat himself down at the bar. Yet again, a television screen was flickering on the wall, this time bearing footage of an interview with Walt's erstwhile colleagues at Gray Matter, Elliott and Gretchen Schwartz. "I can't speak for this Heisenberg person," said Gretchen, as she sought to distance her company and all credit for its success from Walter White. But whatever he became, the sweet, kind, brilliant man that we once knew long ago, he's gone. And, sure enough, when the camera returned to Walt's barstool, he had vanished. By the time the police burst through the door he had become again, at last, a man of action: Heisenberg once more, off to deal with unfinished business. And so the agonising wait for the final episode begins.
