"Fly" is the tenth episode of the third season of American television crime drama series Breaking Bad, and the 30th overall episode of the series. Written by Sam Catlin and Moira Walley-Beckett and directed by Rian Johnson, it aired on AMC in the United States and Canada on May 23, 2010. Produced as a "bottle episode", "Fly" differs from the other episodes in its slow pacing, absence of most major characters other than the two leads, and relative lack of action. It was highly acclaimed by critics, and some have considered it to be one of the greatest episodes of the series. Plot Walter "Walt" White, suffering from insomnia, stares up at his smoke detector's flashing light while trying to get back to sleep. Later, he arrives with Jesse Pinkman at the meth lab, where they begin making another batch of meth.

Jesse, who has been secretly taking small amounts for personal distribution, suggests it may be from spillage or other losses, but Walt insists there is another reason. After Jesse leaves for the day, Walt sees a housefly in the lab, which he fears could contaminate the meth-making process. He tries numerous means to swat it, even dangling precariously from the lab's catwalk, from which he slips and falls to the floor. When Jesse returns the next day, he finds Walt still in pain from the fall and demanding that they cannot start cooking until they get rid of the fly. Jesse worries about Walt's lack of sleep and suggests they go outside to figure it out. However, when Jesse leaves, Walt locks him out of the lab and goes back to find the fly. When Jesse disconnects the main power to the lab, Walt lets him back in so they can work together. Jesse gets some flypaper which they hang around the lab, as well as some sleeping pills that he secretly puts into Walt's coffee. He then recounts a story about his late aunt, who experienced auditory hallucinations as a result of her cancer spreading to her brain. Walt asserts that he is still in remission. As they wait to catch the fly, the two talk about their families. Walt states that he should have died already and tries to think of
