Walter, Jesse and Hank all face some big decisions in this episode. A lot of it is about loyalty, and trying to do the right thing and deciding what they value most.
First of all, though, poor Gale. Gale is just so earnest, so hopeful, so ass-kissy but well-meaning. Gale dressing more like Walt is the perfect detail. It shows so much about his character, and about the power dynamic. Walt is in charge, Gale is the supplicant. But it annoys Walt. And I totally get that. Gale just has to top it off with “This could be the start of a beautiful friendship.” Oh it’s just too much for Walt, who needs to find a way to appease Jesse, as a way to appease Skyler. I don’t think Gale actually messed up the batch. He’s too meticulous, too ready to attune the lab setup, and himself, to Walt’s every whim, that I just don’t believe he screwed up the temperature. Walt just wants to make him feel bad so that he can have an excuse to fire him. I think it’s one step more than that though. I think Gale is a little too smart for Walt. Making Gale feel like crap, like he turned a badge into ruined sludge, makes Walt feel better, the superior alpha chemist.
