Complete story — includes the ending
After hearing Skyler's reasoning, Walt angrily drives the Challenger to a parking lot; he takes it on a joyride, crashes it, and blows it up, forcing Saul to cover up the outburst. Skyler, taken aback by the amount of money Walt makes, is unsure how she will launder all of it through the car wash successfully. Walt convinces Jesse to use his new position as a henchman in the organization to kill Gus, concocting a ricin poison in the lab which Jesse hides in one of his cigarettes. At a meeting, the cartel offers Gus an ultimatum, which he rejects; Jesse has an opportunity to kill Gus, but decides not to. He returns to his 12-step group, where he is kicked out by the group leader after admitting to using the group as a market to peddle meth. Hank visits Los Pollos Hermanos with Walt Jr. and obtains Gus' fingerprints from a cup. Hank later informs Gomez and his boss at the DEA of his investigation that Gus leads a large meth operation, revealing that he has found a match for Gus' fingerprint at Gale's apartment.
