Later, outside the industrial laundry as Walt's about to drive off, he warns Jesse that if he's skimming meth and Gus finds out, he won't be able to protect him. Descending the ladder, Jesse spots the fly and swats. Half-asleep, Walt clutches the ladder while Jesse swats. Jesse wheels over two steel carts, precariously stacks a ladder atop them and starts climbing. On the baby monitor he could hear Skyler singing Holly a lullaby.
Walt, becoming groggy, says that earlier the same evening he had been watching TV. Walt ruminates further on when the perfect moment occurred, and reveals he stopped at a bar, where he met Jane's father, Donald Margolis. Walt tells Jesse that he's lived too long, struggling through his own guilt and anger, expressing frustration that he cannot make Skyler comprehend his motivation for cooking. Ginny had given the opossum a name, "Scrabbles". Ginny would tap on the floor with an umbrella yelling at the opossum to keep it down. Jesse tells Walt the story of an opossum that took up residence beneath his aunt Ginny's house, he continues, but even after it had been removed she insisted it was still there. Jesse prepares coffee and slips some sleeping pills into Walt's cup in an effort to force him to get some much-needed sleep. The partners hang them throughout the lab. Walt deems the nontoxic glue strips acceptable. Jesse shows Walt the assortment of pest control supplies he has purchased. However, after Jesse passes through the doorway, Walt snatches his keys and locks himself in the lab. Jesse counters by shutting off the lab's main circuit breaker and asking the laundry workers for an axe. Jesse convinces Walt that they should step outside and get some air. Reeling, Walt crawls on the floor looking for the fly's corpse, but finds only a stray raisin. Jesse, relishing the opportunity to get back at Walt, swats hard. After a scuffle, the fly lands on Walt's head. Walt orders Jesse to wait until the fly is caught, and smacks him with the swatter when Jesse continues anyway. Jesse works furtively to keep their current batch of meth, halfway through the cooking process, on track. Jesse has to force his way into the superlab Walt has dramatically increased the air pressure to address what he calls a "contamination". Jesse initially assumes that Walt is talking about a dangerous disease, and is nonplussed when Walt tells him the contaminate is a fly. He places it back, not willing or able to throw it out.
Before exiting his own car, Jesse looks at his ashtray and notices lipstick on an old cigarette butt left by Jane Margolis months before. Jesse arrives at the industrial laundry the next morning to find Walt's Aztek still parked outside. As Walt attempts to recover, the fly lands right on one of the lenses of Walt's eyeglasses. When Walt tries to swat at the fly with a broom, he falls from the catwalk onto the concrete floor. Balancing dangerously on the outer rail of the lab's catwalk, Walt attempts to dislodge his shoe. Walt ends up breaking an overhead lamp with his shoe, which gets lodged in the ceiling. His efforts become increasingly desperate as he chases it all over the room. Walt rejects these hypotheses, but admits that "the vestiges" left from their cooking process could possibly account for a portion of the missing meth.Īfter Jesse leaves for the day, Walt becomes distracted by a fly that is loose in the lab. Jesse suggests spillage, evaporation and condensation might account for the discrepancy. Later, after he and Jesse scrub the equipment in the superlab, Walt pores over calculations and notes that the meth yields are consistently short. Walt lies awake at two in the morning in his condo, staring up at his smoke detector's flashing indicator light. Over disjointed, extreme closeups of a common housefly, Skyler softly sings a lullaby to Holly.
