In the middle of the desert, Walter White addresses Declan and his bodyguards about the methylamine deal Mike and Jesse Pinkman had previously arranged. Declan is not pleased to hear there's no methylamine and that Walt is keeping it all for himself. Walt offers to continue cooking his 99.1% pure Blue Sky. Walt explains that the substantial difference in quality between his and Declan's product (±70%) means they attain a higher yield, which means they have more control over price and by extension a higher a profit margin. He offers Declan's organisation the chance to buy out Mike's 1/3 share and be Walt's distribution channel, guaranteeing that they would make more money with that cut than they would on their own. To further prove his point, Walt demands that Declan "say his name", to which Declan feigns ignorance. But after a little more convincing and at Walt's insistence, he resignedly agrees and acknowledges Walt as "Heisenberg".
Back at the Vamonos Pest headquarters, Mike takes his $5 million from Declan and says his farewells to Walt and Jesse, whom he warns to watch out for himself. As they share a last farewell handshake, Walt glares at them as he spies from behind a dirty window. After, Walt and Jesse retrieve the methylamine from the car wash to a load of worried questions from Skyler White who begs to be informed what's going on. Walt tells her to just ignore their actions because he has everything under control and will be out of her hair in no time if she'll only allow them to get on with it.
Dan Wachsberger is depositing hush money to Gustavo Fring's former crew at Craddock Marine Bank. These include $15,000 into nine safety deposit boxes and a much larger sum into one final box that's now filled to the brim. In the parking lot, Mike thanks him and asks if he'll continue with the remaining funds for the nine families, to which Dan reassures him that he will.
At an undisclosed location in the desert, Mike, after hearing via the bug that Hank is all chuffed to have arranged a search warrant for his place, he gets a move on and dumps his surveillance gear and arsenal of guns into an old well. He then hides a duffle bag in the trunk of a second car and leaves it in a long-term parking lot at the airport, hiding the keys nearby. At home, he makes a cup of coffee and waits for the DEA to arrive with said search warrant, personally served by a gloating Hank Schrader. He watches a film as they search his apartment but find nothing, much to a frowning Hank's chagrin.
At the Vamonos headquarters, Jesse arrives to talk to Walt about getting his $5 million so he can depart the meth trade. Walt ignores him and pretends as if Jesse will just pick back up and join him in cooking, even all jovially handing him his blue lab gloves. When Jesse continues to refuse, Walt reminds him that they are the best at what they do (cooking meth) and that since Jesse has nothing and no one in his life, it is a complete waste to give it up and claims he will soon start using drugs again. Walt acknowledges that he knows how upset Jesse is over Drew Sharp's murder and claims he is just as upset as he is, however, given Walt's previous non-affected attitude Jesse asks if he really is. Shocked, Walt growls how Jesse can say that to him and reminds him he is a father himself and questions if he has to curl up into a ball of tears or lock himself in a room and get high to prove to Jesse of his "remorse". Walt claims he is torn up inside about Drew's murder and that it is a tragedy but questions why he needs to lie down and die with him (referring to Jesse giving up cooking). He claims the situation is done and it makes him sick that it happened along with everyone else who has died in their wake. He reminds Jesse they have done things that are just as bad as what Todd did given all the people they've killed such as Gale and tells Jesse that if he is a believer in hell then he can rest assured they are both pretty much going there but Walt claims that until he gets there he will not be lying down. Jesse angrily questions just because he's choosing to give up cooking meth means he's lying down and asks how many more people will die because of them and Walt assures him none. However Jesse's eyes are finally open to the hissing, spitting manipulator in front of him, and claims it is bullshit every time Walt says no one else will die. Walt then refuses to give Jesse his money, claiming it is " blood money" so since Jesse is so remorseful he will spare him the pain by not giving it to him. Jesse finally gives up and leaves, saying he doesn't even care about his share of the money if Walt's unwilling to give it to him. As Jesse walks out, Walt, frustrated and incensed at his slipping control of Jesse, yells after him that if he leaves now he will not receive a single penny.
At a DEA supervisor meeting, SAC Ramey tells Hank to drop the tail of Mike Ehrmantraut and that the Fring Drug Empire case is effectively closed. He's chastised for neglecting all his many other cases and told to shape up to the obligations of his new position. Steven Gomez arrives and the two talk about the lawyer of the nine henchman, Dan Wachsberger, and decide to divert their attention to following him instead.
Walt and Todd Alquist, Walt's eager new protégé, prepare to cook a batch of Blue Sky in In a bug-bombed house. Walt asks him to try his best and listen as close as possible. Todd attentively takes notes while they cook and seems to give his 100%. At the end of the cook, Walt looks slightly let down, clearly missing Jesse, but realizes that Todd is putting in his full effort. When Walt wants to talk money, more so in an effort to boast and impress, Todd refuses a salary until he better knows what he's doing.
Back at the bank, Dan begins to drop more cash for the families, but neglecting to lock the door behind him, is soon surprised by Gomez and the DEA in the vault. At the White Residence, Walt attempts to have a microwave dinner with Skyler who walks out of the room the minute he sits down and starts talking. The next day at Hank's office, Walt visits with another bout of crocodile tears, pretending that he's distraught about Skyler and sobbing she no longer loves him. Hank again fidgets, not knowing what to say or do with himself, so is relieved when Walt requests a cup of coffee. Walt quickly retrieves bug and ethernet tracking device, as per Mike's last command, before Hank returns to drink their coffees in awkward silence. Gomez calls Hank out the office, excited to report that Wachsberger has flipped and is willing to rat out Mike - an eavesdropping Walt almost chokes on his coffee, as he attempts to mask his rising trepidation.
At the park with Kaylee Ehrmantraut, Mike receives a call from Wachsberger inquiring his whereabouts. Mike tells him which park and hangs up, but is clearly uneasy. Seconds later Walt calls and tells Mike that Wachsberger has flipped and the police are coming for him now. Mike shoots up and looks about, just as a police car pulls up across the park. Mike moves behind the nearest tree, deciding either to tell Kaylee goodbye and be arrested or to escape the police and leave Kaylee for good. As a second police car appears, he reluctantly decides to escape, presumably leaving his granddaughter unattended for an extended period of time.
At his office, Saul chastises Walt and Jesse for using Wachsberger in the first place. Mike calls and asks for Saul to retrieve his stashed duffle bag from the parked car, although Saul refuses, speculating he's being watched since the DEA know he is Mike's lawyer. Jesse immediately offers to help but Mike refuses as he doesn't want him caught. Finally, Walt agrees to do it. When he gets to Mike's stash, he looks into the bag in the trunk - it contains some bundles of cash, a passport, and a handgun.
Mike waits for Walt to arrive standing next to a riverbank. Walt finally does but demands that Mike tell him the name of his nine henchmen before he gives up his bag. Mike refuses, then calmly walks up and wrenches the bag out of Walt's hand. Another intense moment erupts between the two, as Mike is angered by Walt's insistence that he's owed at least some gratitude, on Mike leaving with a simple 'goodbye' but no 'thank-you'. Walt blames their predicament on Mike for using an outside lawyer instead of Saul to do the dirty work and allowing himself to be followed by the DEA. Mike, now truly frustrated, blames Walter for everything that's happening since he decided to oppose Gus Fring. Mike growls in Walt's face, then gets in his car to drive off. Walt is left clenching his fists in surging ire, unwilling to accept the truth in Mike's words. When Mike checks the bag, he discovers that the gun is missing from it's holster, just as Walt, seething out of frustration and anger, walks up to the window and uses Mike's own gun to shoot him - a single shot, the bullet shattering through the glass and into his stomach. Mike steps on the gas only to soon veer off and crash into a nearby rock. Walt is left agape, realizing what he has just done, then runs over only to find the car empty. He frantically looks about, but soon finds and follows Mike's footprints. He finds Mike sitting down on a rock, calmly watching the flow of the river, a gun in one hand, gripping his wound with the other. Walt takes the gun from him and comments that he just realized he could have gotten the names from Lydia, and he apologizes to Mike about how this could've all been avoided. Mike interrupts him and tells him to let him die in peace. The two watch the sun about to set and the river in silence until Mike quietly slumps over, finally succumbing to his wound.
