The episode opens on the pink teddy bear previously seen in other episodes. The bear is put into a container along with other retrieved items as men in hazmat suits continue to clean the area. Two of them carry the container past Walt's Aztek -- its windshield broken -- and two body bags lying in the driveway of the White residence.
As Walt prepares to return to work, Skyler convinces him to stay home, wanting him in good shape for a party she is planning celebrating his remission. As soon as she leaves, Walt calls Jesse. The duo eat at Taco Sal, where Jesse is happy to hear that Walt is in remission. Jesse wonders how they'll proceed "in light of this kickass news." Walt says that he plans to retire from the drug trade after they unload the remaining meth.
At Walt's party, Skyler thanks everyone for their support and toasts the absent Gretchen and Elliott. Walt's own remarks are brief and met with further, awkward silence: "When I got my diagnosis — cancer — I said to myself, you know...'Why me?' And then... the other day when I got the good news... I said the same thing."
Chatting poolside with Walt and Junior, Hank says that the "cartel boys" were being "poetic" when they delivered Tortuga's severed head on a tortoise rigged with explosives. Walt, angry that Junior is more impressed with Hank's story, pours tequila shots for the three of them. Despite Hank's protests, Walt pours two more rounds of tequila and, when Hank takes away the bottle, angrily demands that he give it back. The tension builds until Junior, sick from the tequila, stumbles to the pool and vomits. While Skyler attends to her son, an obstinate Walt downs another shot.
At Jesse's apartment, Jesse awkwardly prepares Jane a surprise breakfast of huevos rancheros. Meanwhile, Walt leaves an apology on Skyler's voicemail for his behavior at the party. He starts washing the dishes, but stops when the faucet spits out brown, frothy water from the house's faulty water heater. At work, Ted bumps into Skyler while she listens to Walt's message. During their conversation, Skyler explains that Walt has cancer, but that they got good news last week. Walt heads to the hardware store and is proud to pay cash for a top of the line tankless water heater. Counting out the bills, he discreetly pockets a twenty that's smeared with blood and tells the clerk he'll install the heater himself.
Jesse and Jane lounge in bed while she peruses superhero sketches Jesse drew as a kid. Someone knocks on Jane's front door. Without explanation, she races out Jesse's back door and into her own apartment. Jane greets her father, Donald Margolis, just before he uses his key to open her door. While they talk, Jesse emerges from his apartment and introduces himself, but Jane brushes him off as the "new tenant".
After testing the new water heater, Walt apologizes to Junior for his actions at the party. "But I kept up, right?" Walter Jr. asks. "You and Uncle Hank — I drank three." Concerned, Walt shuffles out of the room. Later, Walt goes back to the hardware store and loads up on supplies to dismantle the rotted floor in his utility closet. Later, Junior comes home and finds Walt sawing away under the house. Meanwhile, Jesse confronts Jane about how she treated him in front of Donald, believing that she is embarrassed by him. Jane responds that she can't admit to her father that she is sleeping with a stoner living next door. Disgusted, Jesse leaves.
Working late, Skyler gets teary-eyed with Ted, confessing she feels guilty for not feeling better after Walt's good news. "Being that rock" for one's family "takes everything you've got," Ted tells her, putting his hand on hers. She withdraws her hand, but then returns it.
The next morning, Skyler and Junior eat their breakfast in silence as Walt continues his construction project. When he takes a break to eat some toast, Skyler asks Walt if he's going to work that day; instead, Walt is obsessively dealing with the rot. At work, Skyler deliberately upends her penholder to draw Ted's attention. When he comes to her aid she plays with her hair and flirts with him.
In his apartment, a distraught Jesse smokes meth and curls up in his recliner. A sheet of paper slides under his door. It's a sketch of a superheroine named "Apology Girl", leaving Jesse smiling.
Back at the hardware store, Walt notices acetone, lye, and other meth supplies in a shopping cart being driven by a tweeker. Walt approaches him and advises him to, "Do it piecemeal...Different items, different stores." Spooked, the tweeker runs away. Walt gets in line to purchase his own selections but suddenly changes his mind and heads to the parking lot. Staring down the tweeker's burly pal, Walt says, "Stay out of my territory." Properly intimidated, the two jump in their RV and Walt watches them drive away with a look of grim satisfaction.
- Jesse references the This Is Your Brain on Drugs ad campaign.
- The type of coating Walt gets is a brand called "KILZ", possibly a reference to his criminal life, because a slogan for "KILZ" is "KILZ EVERYTHING".
- The water heater purchased by Walt is from the Bosch Therm 520 range.
- The rot under the house isn't as bad as Walt makes it out to be. Walt's just keeping himself busy with something he'd rather be doing, reluctant to go back to a job he no longer 'needs' now that he has more ready cash than ever before.
- The rot/fungus running through the house is a good analogy for the cancer coursing through Walt's body, and his renewed vigour to tackle both now that he's in remission.
