Directed by Looper's Rian Johnson, this episode is seriously a masterpiece. It's the famous Season 3 bottle episode that takes place (nearly) entirely in the meth lab and deals with Walt's unhinged hunt for a fly that has invaded the lab. Walt's quest to rid the lab of contamination from the fly harkens back to his rot disposal in "Over," but Walt is unable to see the growing darkness inside himself. There are some great discussions and character moments between Walt and Jesse here, and the episode itself is a showcase for the acting prowess of Bryan Cranston and Aaron Paul. They absolutely carry an episode that would not have been nearly as effective with lesser acting. There is also a poignant moment when Walt, who has been drugged with sleeping pills by a well-meaning Jesse, nearly tells Jesse about the night of Jane's death. "Fly" seems to be extremely divisive among fans of the show, with almost everyone either loving or hating it. I am obviously in the former camp, but the main complaint is usually that it really doesn't advance the plot at a critical point in the season. While I agree that it doesn't have major plot elements, it is absolutely crucial to exploring the mindset of Walt and Jesse at this point in the show and it is a brilliant character study. It also serves as the calm before the storm that we all know comes to fruition in "Half Measures" and "Full Measure." "Fly" is a terrifically unique episode that works perfectly. Memorable Quote: Walter White: "I told him that I had a daughter and he told me he had one, too. And he said, "Never give up on family." And I didn't. I took his advice. My God, the universe is random, it's chaos. It's subatomic particles and endless pings, collision that's what science teaches us. What does this say? What is it telling us that the very night that this man's daughter dies, it's me who is having a drink with him? I mean, how could that be random?"
