Cut to Lydia presenting her plan to all three men. She lays out a map (convenient!) and explains that a train leaves Long Beach at 3:00 PM, destined for Flagstaff and parts beyond. If that train is pulling a tanker full of 24,000 gallons of methylamine passes through a dead stretch of New Mexico desert where they'll be cut off from any and all communications, how stupid do three drug dealers have to be to try to rob it? Show your work. Jesse's like, "Rob it? Like Jesse James?" Lots of love for ol' JJ these last few episodes. Mike thinks this is all a quick way to have the three of them thrown in jail for the rest of their lives. So Lydia explains the concept of this stretch of "dark territory," where any of the train's usual fail-safe alarms and other communications to control will not be operational -- no cell service either. The fact that Lydia has to preface this info dump with "what you don't know, and I do, because my job requires me to keep track of my buyers' shipments" makes me think the writers were at least a little aware of how contrived this whole plot could seem.

Walt asks how they'll even know which car is which, and Lydia says she can provide a manifest that gets uploaded to the Madrigal server six hours before the train is set to reach the dead zone. You know, I get the complaints that it's a stretch to think Lydia could have pulled an elaborate plot like this out of her ass in a pinch, but I could also easily buy that as Lydia worked at Madrigal, these tidbits of information fell into her lap, and she slowly pieced together the perfect what-if, maybe not ever intending to use it. She's a jittery loose cannon, but she's also been involved in a criminal enterprise for years. Not out of the realm of possibility that she's been keeping an eye on possible cracks in the system she could exploit all this time.

Mike's next problem is that they'll have to off the crew. Walt and especially Jesse argue that they wouldn't, but Mike says it's his experience that there are two kinds of heists: "those where the guys get away with it, and those that leave witnesses." Lydia, in a moment I kind of loved, is like "Oh, sorry, suddenly you guys are all anti-murder?" She has a point.

At the Purple Palace, Hank and Marie are doing baby things with Holly, with Hank jokes that he's not going to give Holly back. Hmmm ... Anyway, they turn to the subject of "Emo McGee" (Junior) and how he's been all moody and not taking this exile well. You can't entirely blame him, can you? Marie calls to "Flynn" and offers to heat up lasagna, and Hanks asks if he wants to watch Heat, but Junior's like, "Nope. Keep talking about me, though."
