Walt gets a quiet moment that lands harder than any explosion could. For reasons the episode never fully explains, the hospital keeps coming up. The episode leans on reruns of earlier moments, which is nostalgic the first time and less so the fourth. Long-time viewers get a payoff: "How's about we run through this?" is no longer a mystery. The line of the week goes to "This attack on my brother-in-law, I don't. I don't.", which deserves to be embroidered on a cushion. Reliable, like a well-made chair.
