Skyler had very few options left in this scene. She was grasping for a power play but Walt shut her down. She's trapped in a lion's den in this scene, very vulnerable, and their dialogue is written in a natural way yet packed with underlying menace. I like the point where Skyler (afraid but brave) holds a fist to her chest and defiantly declares, "I got them out of this house." Her victory doesn't last long under the calculating gaze of her husband/Heisenberg. It is one of my favorite scenes in the show...top ten livewire moments.
