Jesse bounds into the main area of the laundry facility, yammering about needing an axe. Everybody pretty much ignores him, which is great. No idea whether Jesse is this frantic because he feels the meth needs to start cooking or just because Walt got one over on him. I'd suspect the latter, but he's been awfully concerned about the former this week. After screaming for "el axe-o," Jesse finds a supply closet and chooses his weapon: a sledgehammer. But then he spies the power grid and has a better (worse) idea. Suddenly, down in the lab, the lights go out, predictably just as Walt was about to take a really good swing at the fly. The auxiliary lights come on so we can see the mess Walt made with that errant swing. Walt checks the lab's internal power grid, and when that doesn't work, he turns to the door and sees Jesse's smirking face. "Need some juice?"

The commercial break has given Jesse time to go to the store for fly-killing supplies, like a proper fly-swatter. Walt sneers at the canisters of bug spray Jesse bought; they're trying to de-contaminate the lab, not contaminate it further. But when Jesse presents pheromone-enhanced glue strips, Walt signals his approval (he does so by declining to insult Jesse's intelligence for five seconds). Cut to the lab a short time later, festooned with flypaper strips hanging like party streamers. Between the steadily unraveling protagonist and all the flypaper, I can't help but think of that rather excellent movie Bug, which, if you haven't seen it, do so. Anyway, with the flypaper up, Jesse offers to pour Walt some coffee, since he's obviously been awake since the Eisenhower administration. He pours some out (from Gale's coffee contraption, aw) and then, when Walt's not looking, he pops about five Sominex in there. So Walt's either going to have to take a long overdue nap or, you know, die. Jesse hands the coffee over and dodges a possible suspicious look from Walt ... but it merely leads to a rare "thank you."
