"A Short Story About Love" centered on a scientist extracting the pheromones of his victims, all male spouses, and using the resulting substances as a perfume to get close to their wives.
First airing on March 23, 2012, in the United States, "A Short Story About Love" was watched by an estimated 2.87 million viewers, a decrease from the previous episode.
They arrive at Carr's home to find another husband, already dead, in a dehydration chamber, and race to protect his wife, Dianna (Ona Grauer).
When no attack comes at the wife, Olivia Dunham (Anna Torv) realizes that her husband may have been having an affair, and races to the mistress' home, stopping Carr before he can kill her.
Walter calls him back, identifying that the Observer September (Michael Cerveris) had implanted something in Peter's eye during the events of the previous episode.
The small disc reveals a nearby address, where Peter finds a stash of September's Observer equipment, including a GPS-like device that leads him to a strange pod (as shown previously in "The Arrival").
