This is such an unsettling episode. Skyler has gone from the cocky, overbearing, self righteous wife, to a depressed, fearful woman with no options. It involves sending the kids to Hank and Marie's house. Much of the episode involves Walter trying to get her to change her mind. I was never a fan of hers but I really see her point here. On the other front, the distributor of a necessary ingredient is sitting in all her paranoid glory. Mike believes she should be killed. Tension in the ranks.
