At the new business HQ, Jesse appears to have contracted some of Lydia's jumpiness, as he shows Mike and Walt camera photos of the DEA tracker stuck to the bottom of the methylamine barrel, which means they can't use Madrigal for their precursor hookup anymore. And, as Jesse helpfully points out, it's not like they have any other sources of methylamine they can tap. Mike tells him to calm down for a second. He's hung up on the shoddy police work of ham-fistedly slapping a tracker to the outside of a barrel instead of dropping one inside. After he gets Jesse to confirm that it was Lydia who spotted the tracker first, he kind of grimly smiles to himself. He thinks Lydia put a tracker on the barrel herself, so it would look like the DEA was onto her, so they would be forced to exempt her from future dealings. So Lydia's got to go. Mike kind of beats himself up for not taking care of her two episodes ago. "That's what I get for being sexist," he muses. Jesse -- not a huge fan of killing small kinks in the pipeline, all things considered -- tries to convince Mike that they need to just tell her to quit freaking out; their source of methylamine is too important to cut off just because she's acting crazy.

This just illustrates the big difference in how these two operate. Mike's willing to ramp down production for a while if it means avoiding a loose cannon who could get them all arrested or killed; Jesse (and Walt) are far more willing to be reckless in order to keep business booming. Besides, says Jesse, Lydia's not a threat; she's just "uptight." Mike: "Now you're being sexist. This woman deserves to die just as much as any man." Well done, sister suffragette! Mike tells Jesse to get out of his way, just as Jesse says they have to vote on it. He votes that they have to vote on it and he appeals to Walt, who has been silently staring at his Heisenberg hat this whole time. Fingering a loose thread on it, in fact, if you're into metaphors. And much as Jesse might think it is this isn't a voting thing. This is Walt once again making the only decision that counts: the methylamine keeps flowing, no matter what. "We are not ramping down. We're just getting started. Nothing stops this train. Nothing."
