After the title card, we see Walt is in for one of his once-a-season cancer checkups. The indignity of Walter White in a hospital gown will never not be hilarious nor poignant. He sits down in a waiting area a few seats down from this severely bummed-out looking young guy who's worried that this test is "the loud one with the magnets." Walter, ever the know-it-all, explains that this is the Positron Emission Tomography(PET)/CT scan. He dumbs it down with a sneer: "Quiet, no magnets." This guy is pretty young -- late 30s, tops -- and super nervous, which means he's in a waiting room with the absolute worst person possible. He starts to talk about his fears, his kids, but Walt rudely and ostentatiously makes a phone call to Jesse's voice mail, demanding a progress report on the "have you killed Gus yet" front. This poor guy obviously wants to talk, and he doesn't know Walter is an asshole. So he keeps talking, about how scary it is to give up control, but you know how they say, "man plans and God laughs." Walt is obviously not above telling this guy that that is a pile of bullshit. "Never give up control," he says, without one ounce of pity. "Live life on your own terms." I'm sorry, WHOSE terms is Walt currently living his life on? "Sure," the other guy says, "but cancer is cancer, so..." "To hell with your cancer," Walt says. "I've been living with cancer for the better part of a year." (Begin freaking out, because these four seasons have covered ONLY A YEAR.) Walt continues, talking about how everybody said his cancer was a death sentence, but guess what? Every life comes with a death sentence. I love tough-talking Walt. He always goes best right before powerless-before-unstoppable-forces Walt. Anyway, he says that every time he comes in for a scan, he knows one of these times will be bad news. "But until then, who's in charge? Me. That's how I live my life."
