Synopsis:
After a required sexual harassment training by Dr. Young, Allison asks Jack to find their biological systems engineer Dr. Stone, who is absent from work, which is a problem due to his work being the maintaining of his creation: Eureka’s biological-based air conditioning. Stone was overhauling the older parts of the system and with him missing, Henry is trying to fix it to no avail.jack asks Allison for the files on Kim’s accident and she’s hesitant being they are classified but says she will see what she can do. Allison goes to Stark and tells him that Carter is looking into things. Stark plays into her fears and says if Carter gets too far into this, it’ll lead right to Kevin and the DoD will take him away for study. He decides he needs access to all of the info about the accident and the lab as well.
Jack talks to Taggart about Stone who had talked with him about getting some new ducts put in for his wolves he was studying, working on getting them to mate through the use of some pheromones he developed. Jack then questions Stone’s wife but she says he can stay below in the tunnel for days sometimes and she just accepts it.
Upon returning to the office, both he and Jo seem to be avoiding calling their prospective love interests when Callie shows up unexpectedly with his cleaning, inviting him out for a weekend trip. Before he can answer, Jo hears a noise from the toilet in the bathroom where she is laser trimming her eyebrows, and she runs out, followed by an explosion. Henry explains that it’s due to the blockages causing the air conditioning issues, making finding Stone even more paramount.
Jack goes to Cafe Diem for lunch and is met by Mrs. Stone who comes onto him very strongly, much to a nearby Zane’s amusement. Jo then shows up and she also begins acting strangely, when Henry calls, yelling at them to get out. Another explosion happens and when the smoke clears, Jo ends up kissing Jack. Back at the office, Jo seems to be acting normally, but Zane is upset by what happened and leaves angrily.
With sewer systems causing water geysers popping up and more explosions on the way, Jack returns to the tunnels of GD to find Stone but ends up finding human bones covered in a thin dust. He reports his findings to Stark when Allison and Dr. Young begin arguing, competing for Jack’s affections with Young even kissing him before they start physically fighting. Jack is removed from the room and the women return to normal, detailing how they felt out of control.
Jack asks Taggart about his pheromones who claim they wouldn’t work on humans. They put it to the test by having women approach Taggart, stripped to his underwear, but nothing happens. They test Jack’s blood and discover that his eccrine gland is producing an overabundance of androstadiene, a hormone involved with sexual attraction, and could overload the female brain into not just attraction but violence. Taggert’s is normal, but one of his wolves’ glands is acting like Jack’s.
Still trying to find Stone, Vincent tells Jack that Stone’s usual lunch was picked up by Mrs. Stone, and they head to her goodie, finding the doctor locked in their bedroom, amidst the signs of a very active “getting busy” session. Stone tells Jack that he and his wife started rediscovering their newlywed days the previous night with Stone expressing regret it wasn’t just the old spark coming back. They go to check out the system and he discovers the problem, working on setting it back to normal.
Taggart is despondent to see that one of his wolves ate the other one due to the androstadiene overload, and calls Jack to get out of view as women start becoming aggressive and start attacking Jack’s car, with him, Fargo, and Stone just barely getting away.
Back in the tunnels, Stone manages to get the system working again, however, Jack sees dust on the floor of the wolves’ room, realizing it was the same dust that covered the bones he found. Taggart tests it and they discover it is responsible for the heightened sexual attraction. Now with the ac back online, the spores are now spreading throughout the town, infecting everyone.
They find a way to develop a counter agent but it will take several days. Jack points out that Henry was in the tunnels but no one is affected by him because he’s wearing an invisible spray-on electrostatic filter. They put the spray into the ac system and they start to see the effects of the spores decrease.
Zane confronts Jo about how he felt about seeing her kiss Jack and the two agree to start communicating and get to the point, with Jo kissing him.
Later Henry goes to get into Kim’s lab, but the door won’t open. Allison tells him she’s shutting it down and that he will be getting a new lab space. Henry confronts Stark but he won’t tell Henry anything. Jack and Callie reconnect and he realizes that when she invited him for the weekend trip it wasn’t because of the spores and they make plans to go.
