Complete story — includes the ending
Mike assures Walt that Jesse is safe and he takes Jesse on multiple collections throughout New Mexico. During the last collection, a man appears with a shotgun, and Jesse thwarts the robbery attempt. Later, Gus and Mike discuss the day and it is revealed that the "robbery" was set up by Gus to improve Jesse's low self-esteem. Walt and Skyler officially purchase the car wash, after which Skyler asks Walt to move back into the house. During a family dinner, Hank reveals that he has given up on investigating Gale further, having found a sense of closure in the death of the man he believed to be Heisenberg. When Hank states that Gale was a genius, an intoxicated Walt lets his ego get the better of him, and tells Hank that he believes Gale most likely copied someone else's work and that Hank's "genius" is still at large. The following day, Hank dives back into the case with renewed vigor and discovers a Los Pollos Hermanos napkin amongst Gale's possessions.
