Stan introduced Walter and Skyler White to their new house at 308 Negra Arroyo Lane about 15 years earlier. Having been told earlier by Skyler about Walt's profession as a scientist at the Sandia National Laboratories, Stan jokingly asked Walt if he was researching space lasers. Walt replied that what he did was too boring to talk about, but that he'd be sure to bring the idea up at the next staff meeting. Laughing, Stan told Walt to make sure that he received a cut of the profits. He then said that he'd give Walt and Skyler some privacy, and left to go to his car to make some calls ("Full Measure").
