Half Measures

It originally aired on AMC in the United States on June 6, 2010.

Skyler White pushes Walt to accept her plan of laundering his drug money through the car wash. Meanwhile, Jesse Pinkman begins to plot against the drug dealers who killed Combo Ortega. He buys blue meth from the gang responsible, confirming that Combo's killers work for Gus Fring. Jesse tells Walt and asks him to make ricin to exact revenge. Although Walt appears troubled by the gang's use of children, he dismisses the plan. Jesse replies he will kill them with or without help.

Convinced Jesse is likely to do something rash, Walt visits Saul Goodman and they plan to have Jesse jailed, albeit briefly, to cool down. Meanwhile, Marie Schrader wheels Hank out of the hospital, after betting she can arouse him during a sponge bath.

Mike Ehrmantraut makes an unannounced visit to Walt at home and reveals he also works for Gus, who would "take it as a problem" if Jesse would be jailed. Mike then tells Walt a story from his years as a cop, in which he laments over showing mercy to an alcoholic, continually abusive husband who subsequently killed his wife. Mike tells Walt he chose a "half measure" instead of killing the husband, and warns: "No more half measures."

Jesse plants ricin in hamburgers intended for Gus' dealers but is unable to find them at their usual location. He is stopped by Mike and Victor who bring him to a meeting with Gus, Walt, and the two targeted dealers. After tense negotiations, Gus promises his dealers will stop using children as pawns, and Jesse reluctantly promises to "keep the peace." On their way back, Walt tries to calm down the furious Jesse, who refuses to respond.

That night, Tomás is killed, and Jesse and his girlfriend Andrea rush to the scene. He realizes the two street dealers have executed Tomás, as he is no longer of value to them. The next day, Jesse fails to show up for a cooking session with Walt, who decides to start without him. During dinner with his family, Walt learns the same news on TV and abruptly leaves.

Jesse watches the dealers from afar and snorts meth for the first time since rehab. He draws his gun and slowly approaches the two dealers, who draw their own guns and prepare for a confrontation. Suddenly, Walt plows into both dealers with his car, killing one and badly injuring the other. Walt gets out of his car, picks up the injured dealer's gun, and shoots him dead. Walt then tells an utterly shocked Jesse one word: "Run."
