As Jesse keeps his eye on the dealers responsible for Combo's death, Walt, teaching his son how to drive, is pressed by Skyler about buying the car wash. Walt uses the opportunity to bargain time at home with his family: even though the two of them are not even close to being a loving couple now, they agree on letting Walt stay over for dinner four nights a week, in order to create a facade that they are a loving family.
Afterwards, Jesse and Walt meet at a bar. Jesse reveals to Walt that he had purchased their meth from dealers working for Gus, the same ones that had Combo killed. He asks Walt for some ricin, the self-same poison they originally planned to kill Tuco with. Walt refuses, calling Jesse's desire for vengeance "ridiculous" and stating that killing the dealers would accomplish nothing. Jesse, however, is deaf to reason: he plans to kill the dealers, with or without Walt's help.
As Hank continues to refuse to go home until he can walk, and Walt and Saul discuss what to do with Jesse: Jesse prepares his own ricin, and instructs Wendy, whom he saw giving lunch to the dealers in exchange for meth, to give the dealers his ricin-laced burgers, playing to Wendy's maternal instincts and asking her what she'd do if she found out her own son was working for drug dealers.
Mike pays Walt a surprise visit that evening. Walt and Saul had discussed having Jesse arrested and put into community service to cool his head, but Mike states that he and Gus are ultimately against the idea, since Gus would consider Jesse's arrest problematic. To demonstrate his point, Mike tells Walt about a criminal he knew in his days as a cop: a notorious wife-beater. One day, Mike arrested the wife-beater, and pulled into a dark alley to kill him. He ultimately decided against it, but warned him not to hurt his wife again. For his act of mercy, Mike was "rewarded" with the wife being murdered not long after. He felt responsible for her death because he took a "half measure". Before he leaves, he gives Walt some parting advice: "no more half measures".
Before Jesse can carry out his plan to assassinate the dealers, Mike arrives, driving Wendy off and apprehending Jesse. They take Jesse to the Los Pollos Hermanos factory farm, where Walt, Gus, and the dealers are waiting.
Gus concedes that Combo's death was a rash act, but in the dealers' defense, Jesse had him selling on Gus's territory. Jesse calls Walt out on selling him out, but Gus tells him that he only has one friend in the room, and if not for Walt, things would turn out differently. He instructs Jesse to make peace with the dealers, but Jesse refuses, telling Gus they use kids. Although cross with Jesse, Gus decides to grant him this one indulgence: he states plainly, "No more children", and has Jesse shake hands with the dealers.
Back at the hospital, Marie, determined to bring Hank home, makes a deal with him: if she could get him to achieve an erection, he would have no choice but to come home. Hank reluctantly accepts, and warns Marie of the futility of her proposal. In the end, however, she manages to get a rise out of Hank: he leaves the hospital looking humiliated and defeated as Marie looks smugly triumphant.
That evening, Jesse is enjoying Andrea's company when she receives a phone call that leaves her distressed, and Jesse gobsmacked: Tomas has been murdered!
Walt tries to call Jesse the following day, but to no avail. When he hears of Tomas's death on the evening news, however, he realizes why he can't reach Jesse and storms out...
Jesse is at the street where Combo was killed. He takes a hit of meth to muster some courage, then makes his way to the dealers, prepared to kill them.
As they start to draw their guns, however, Walt suddenly appears, running over the dealers with his car. One is killed instantly, and Walt takes the other's gun and shoots him in the head before looking at Jesse and giving him a simple instruction:
This episode contains examples of:
- Analogy Backfire: Mike explains his Start of Darkness to try to talk Walt out of a half-measure attempt to save Jesse from killing the two rival drug dealers after Tomas' death.

- Even Evil Has Standards: Jesse's Big Brother Instinct kicks into overdrive when he finds out the dealers that had Combo killed are using a young boy to do much of their dirty work. Jesse's clear intent to exact revenge angers the dealers' boss: Gus. Things rapidly spiral out of control for Jesse and Walt as a result.
