We also meet a new player in "Madrigal." Lydia's a nervous sort and she sees people as loose ends to be tied up - or shot to death. Mike doesn't want to have anything to do with Walt (who he refers to as a "time bomb" - a comment that's more true than he knows), but the DEA found and froze the offshore accounts - indirectly through Walt's utter inability to know when enough is enough - and there's no money. So Mike gets Lydia onboard to get the necessary methylamine to start cooking again and a three-way partnership is formed between Mike, Walt, and Jesse, albeit a reluctant one.
Last thing. Jesse breaks down at the thought that he nearly killed Walt over what he thought was Walt's attempt to poison Brock with the missing ricin. Shoulders shaking, voice strained, he sobs and sobs and my heart breaks a little bit more. For Walt did poison Brock - remember the potted lily-of-the-valley Walt dumps in his trunk? Walt has hidden the ricin vial and created a dummy vial filled with salt which he then helps Jesse "find" to prove his innocence. Seeing Walt comfort his crying partner points up the fact that this Walt is thoroughly despicable as well as being truly dangerous. Walt's willing to go to any length - any - to keep Jesse close and dependent and the "no rough stuff type deal" Walt has been shed like an outgrown snakeskin. Jesse's no saint, but at least his eyes haven't gone dead.
It's not going to go smooth, is it?
Let me also bring to your attention my co-author's blog, which is now featuring "Meth Monday" as a companion to these "Walter White Wednesday" posts. Check it out - we find different things in each episode, so the two blogs are good to read together.
*A "madrigal" is also vocal music composition dating from the Renaissance era. Most usually, a madrigal contains from three to six voices. It'll be interesting to see how many "voices" play a sizable part in telling the "Madrigal" story.
