In [[sickbay]], [[Nurse]] [[Alyssa Ogawa]] removes spines from [[Commander]] [[William T. Riker|Riker]]'s back; an accident in the [[arboretum]] had resulted in a close encounter with a [[Cyprion cactus]]. Meanwhile, [[Lieutenant]] [[Reginald Barclay|Barclay]], having diagnosed himself with a lethal illness, goes to see [[Doctor]] [[Beverly Crusher|Crusher]] - who assures him that he in fact is not suffering from any lethal illness, but instead has a mild case of [[Urodelan flu]]. [[Human]]s typically exhibit a natural immunity to the flu, but since the [[T-cell]]s that would normally fight off the [[infection]] are dormant, she activates that particular [[gene]] with a synthetic T-cell to let his body fight the infection naturally. [[Data]] soon arrives carrying his [[cat]], [[Spot]]. The cat is here for a routine check on the progress of her pregnancy; she is expected to deliver before the end of the week. The talk of babies prompts Ogawa to reveal that she is herself pregnant, prompting congratulations from Crusher.

On the bridge, Lieutenant [[Worf]]'s new weapons guidance system is being put to the test. However, out of three [[photon torpedo|torpedoes]] launched, only two hit their targets, while the third swerves off course. With the {{USS|Enterprise|NCC-1701-D|-D}} unable to follow and disable the other torpedo due to a dense [[asteroid]] field ahead, [[Captain]] [[Jean-Luc Picard|Picard]] and Data leave the ship to disarm the torpedo via a [[shuttlecraft]]. Before they leave, however, Data asks Barclay to watch over Spot. The cat might deliver before his return, and Barclay is one of the few people that Spot tolerates.

As time passes on the ''Enterprise'', several crewmembers start displaying strange behavior. After being ordered to take a break from checking the problems with the guidance system, Worf shows signs of becoming increasingly irritable and very hungry. Meanwhile, [[Counselor]] [[Deanna Troi|Troi]] finds the [[atmosphere]] too dry and cold, constantly changing around the ambient [[temperature]] and [[humidity]] levels and consuming large amounts of [[salt]]y foods and [[water]]. That night, Worf's behavior degenerates further and becomes more primal: he rips up his bed and sleeps tensely on the floor.

In [[engineering]], Lieutenant Barclay shows his own strange behavior. He seems unusually energetic, speaking so rapidly that [[Geordi La Forge|La Forge]] and Riker are having difficulty keeping up with him. Riker's inability to keep up with Barclay is compounded by his own problems; he is having trouble with his memory and higher thinking.

A problem detected in engineering has Barclay and La Forge in the [[Jefferies tube]]s. Barclay finds and bypasses a ruptured [[plasma conduit]]. As he does, La Forge detects [[Cholic acid]] around the hole in the [[Bulkhead]] where the ruptured line was located. The bulkhead and [[Conduit]] seems to have been dissolved by an [[organic]] solvent. But in contrast to Barclay's increasing hyperactivity, La Forge seems increasingly lethargic. Barclay suggests a [[Biospectral analysis]]; La Forge agrees before deciding to take break.

The changes being experienced by the crew continue to progress. Riker finds himself unable to either remember the recent weapons testing or respond to a [[Starfleet]] request for a report on the matter. Troi sits in her bathtub, trying to stay wet when Worf suddenly enters her [[quarters]], approaches Troi, and bites her cheek.

Troi sits in her bath tub, wearing her [[Starfleet uniform (2350s-2370s)|Starfleet uniform]], trying to stay wet when Worf suddenly enters her quarters, approaches Troi, and bites her cheek.
   
Both Troi and Worf are taken to sickbay, and Crusher quickly notices the changes. When Ogawa adds that more of the crew are experiencing similar symptoms, Crusher concludes that something is spreading around the ship. She then turns her attention to Worf, and notices something else: he has swellings under his jaw that appear to be venom sacs. They prove to be just that as Worf suddenly spits/sprays venom in Crusher's face, then flees sickbay before he can be captured.

They prove to be just that as Worf suddenly sprays venom in Crusher's face, then flees sickbay before he can be captured.
   
In the [[observation lounge]], Ogawa reports that she got Crusher into [[stasis]] before she became paralyzed by the venom. However, there is still the problem of the mysterious illness affecting the crew. Barclay reports that the venom that affected Crusher has been found in other parts of the ship, including at the ruptured plasma conduit seen earlier. Riker admits to his inability to think straight; he can't think properly when La Forge reports on having trouble locating Worf on [[sensor]]s, or even compose a [[subspace message]] to Starfleet concerning their problem.

Picard and Data are a little puzzled to not be able to locate the ''Enterprise''. A quick search locates the ship, visibly unmanned and adrift. Upon docking, they ascertain that the ship's power systems are down, environmental systems are configured strangely, and where there should be over a thousand humanoid lifeforms there seems to be a near-equal number of myriad creatures. Some of the characteristics are inconsistent with those of the known crew, such as casting off skin like a [[reptile]]. They come upon Troi's quarters and discover her in her bathtub, having somehow developed into an [[amphibian]]-like creature. It is their first clue that the crew is undergoing unusual changes.

Seeking to stabilize the ship, they then go to the bridge, finding it in shambles, with a dead [[Dern (flight controller)|ensign]] at the conn (from what appears to be an animal attack); he'd also been affected but had been killed before undergoing anything significant. From the bridge, Data is able to note that the crew is still on board the ship but in a similar state to that of Troi. Many of them have been gravitating towards water (the aquatic lab) and plants (the arboretum). Picard is unable to restore power to the ship due to the entire power-transfer grid being damaged. Suddenly, they hear a noise coming from the [[ready room]]. Inside, they discover Riker attacking the captain's [[aquarium]] (inside the presumably break-resistant aquarium, Livingston, Picard's pet lionfish, has also de-evolved, into a jellyfish) after having apparently turned to a proto-Human. When he charges, Data stuns him. Based on what they've encountered so far, Data begins to suspect that the crew is de-evolving.

=== Act Four ===
Troi and Riker are taken to sickbay for further analysis. Data, after analyzing Riker's [[DNA]], discovers that a synthetic T-cell has invaded his [[gene|genetic code]]s and has begun to activate his latent [[intron]]s, a result of Crusher's treatment of Barclay. He explains that introns are genetic codes which are normally dormant; they are sequences of DNA which provided key physical and behavioral characteristics millions of years ago, but are no longer necessary. Counselor Troi's gill-slits and other amphibious characteristics, for example, are derived from introns which contain amphibious codes. Because introns can include genetic material from many different species over millions of years of [[evolution]], it is possible that a wide variety of transformations is occurring among the crew. Since all humanoid life has a similar genetic pattern, the [[virus]] will work similarly on all non-Human lifeforms as well, and they will each be de-evolving to earlier forms of life in their homeworlds. He informs Picard that he has also been infected by the intron virus, and is now slowly de-evolving into an earlier form of [[primate]].

Realizing that they do not have much time, they decide to act quickly. Since Data's [[computer]] in his quarters operates independently from the ship's computer and is probably still intact, they decide to go there in order to examine the situation further. Arriving at his quarters, Data notices that Spot, who has been expecting a litter of [[kitten]]s, has finally given birth. A further search finds a [[reptile]] wearing her collar; they soon realize that the reptile is Spot and that the intron virus is capable of affecting non-humanoids. Her kittens, however, do not seem to have been affected by the virus that has been plaguing the rest of the crew. Given that Spot's kittens are unaffected, Data and Picard conclude that the [[placenta]]l barriers and [[amniotic fluid]] that serve as a filtration system to protect the [[fetus]] in the placenta have probably prevented the intron virus from being passed on from Spot to her kittens. They decide that they probably can inhibit the intron virus by using the natural [[antibody|antibodies]] in Spot's amniotic fluid. However, in order for it to be effective on humanoid crewmembers, humanoid antibodies would be necessary. Recalling that Nurse Ogawa is expecting, they track her down to the arboretum. But before they can begin tracking her down, a failure in a [[warp plasma]] vent forces them to detour to [[main engineering]] so Data can program repairs. In the interim, Picard is frightened by the sudden appearance of Barclay, partially transformed into a [[spider]]. Data surmises that his terror at the sight (a result of the heightened sense of awareness found in small primates) is an initial symptom of Picard's de-evolution; they need to hurry.

They locate Ogawa (who is apparently partially de-evolved into a proto-Human) begins to analyze Ogawa's fetus, confirming that it is not affected by the virus. He says that he can use her amniotic fluid as a template for a retrovirus which in turn would neutralize the synthetic T-cell and re-establish the genetic patterns of each host. While working on finding a way to most quickly address the situation, something pounds on the sickbay door. [[Life sign]] scans show something big, armored, and [[Klingon]]; it is Worf.

A transformed Worf tries to force his way into sickbay. He appears to be seeking something or someone particular. Picard notices that the bite Worf gave Troi was not to hurt her but rather seemed part of a mating process, and that it appears as if Worf had come back for her. The situation becomes increasingly dangerous as an ever angrier and aggressive Worf almost breaks through the door. Data and Picard cannot just abandon Troi and the others in sickbay, but at the same time, Data needs to continue with his analysis of the amniotic fluid. Picard, who is beginning to experience the effects of the virus himself, suggests distracting Worf and luring him away from sickbay. He suggests extracting [[pheromone]]s from Troi's sebaceous glands to lure Worf away from sickbay so Data can continue his work and the others are safe.

While Data continues work on the retrovirus, Picard leads Worf on a chase through the ''Enterprise'' until becoming cornered at the ruptured warp plasma conduit La Forge and Barclay had been repairing earlier. Picard improvises, sitting upon the insulated access panel and using the bypassed conduit to send [[electricity]] through the Jefferies tube, knocking out Worf. At that moment, Data reports that he has completed the retrovirus. It will make the introns in the crew dormant again; at Picard's consent, he floods the ship with a [[gas]]eous form of the new virus, turning the crew back to normal.

In sickbay, Barclay nervously asks Dr. Crusher if all this was his fault. She states that actually it was ''her'' fault for having activated a dormant T-cell which, in turn, activated ''all'' dormant T-cells (including the introns). She suggests naming the virus after Barclay, calling it the [[Barclay's Protomorphosis Syndrome]]. Jokingly, she tells Troi that Barclay not only devolved into a spider, a creature which he fears terribly, but also had a disease named after him. Troi sighs, realizing that she better clear her calendar for the next couple of weeks.

Template:Realworld

Enterprise crew members de-evolve into prehistoric creatures after a medical treatment by Dr. Crusher goes wrong.

Summary

Teaser

In sickbay, Nurse Alyssa Ogawa removes spines from Commander Riker's back; an accident in the arboretum had resulted in a close encounter with a Cyprion cactus. Meanwhile, Lieutenant Barclay, having diagnosed himself with a lethal illness, goes to see Doctor Crusher – who assures him that he in fact is not suffering from any lethal illness at all, but instead has a mild case of Urodelan flu. Humans typically exhibit a natural immunity to the flu, but since the T-cells that would normally fight off the infection are dormant, she activates that particular gene with a synthetic T-cell to let his body fight the infection naturally. Data soon arrives carrying his cat, Spot. The cat is here for a routine check on the progress of her pregnancy; she is expected to deliver before the end of the week. The talk of babies prompts Ogawa to reveal that she is herself pregnant with her husband's child, prompting congratulations from Crusher.

Act One

"Captain's Log, Stardate 47653.2. We're performing field tests of our new tactical systems and weapon upgrades. Mr. Worf is supervising the exercises."

On the bridge, Lieutenant Worf's new weapons guidance system is being put to the test. However, out of three torpedoes launched, only two hit their targets, while the third swerves off course. With the USS Enterprise-D unable to follow and disable the other torpedo due to a dense asteroid field ahead, Captain Picard and Data leave the ship to disarm the torpedo via a shuttlecraft. Before they leave, however, Data asks Barclay to watch over Spot. The cat might deliver before his return, and Barclay is one of the few people that Spot tolerates.

As time passes on the Enterprise, several crewmembers start displaying strange behavior. After being ordered to take a break from checking the problems with the guidance system, Worf shows signs of becoming increasingly irritable and very hungry. Meanwhile, Counselor Troi finds the atmosphere too dry and cold, constantly changing around the ambient temperature and humidity levels and consuming large amounts of salty foods and water. That night, Worf's behavior degenerates further and becomes more primal: he rips up his bed and sleeps tensely on the floor.

Act Two

In engineering, Lieutenant Barclay shows his own strange behavior. He seems unusually energetic, speaking so rapidly that La Forge and Riker are having difficulty keeping up with him. Riker's inability to keep up with Barclay is compounded by his own problems; he is having trouble with his memory and higher thinking.

On the bridge, Troi (currently on watch) keeps trying to raise the temperature, and Worf keeps turning it back down: complaining it is too hot. Troi finally leaves the bridge to take a bath in her quarters.

A problem detected in engineering has Barclay and La Forge in the Jefferies tubes. Barclay finds and bypasses a ruptured plasma conduit. As he does, La Forge detects cholic acid around the hole in the bulkhead where the ruptured line was located. The bulkhead and conduit seems to have been dissolved by an organic solvent. But in contrast to Barclay's increasing hyperactivity, La Forge seems increasingly lethargic. Barclay suggests a biospectral analysis; La Forge agrees before deciding to take a break.

The changes being experienced by the crew continue to progress. Riker finds himself unable to either remember the recent weapons testing or respond to a Starfleet request for a report on the matter. Troi sits in her bath tub, wearing her Starfleet uniform, trying to stay wet when Worf suddenly enters her quarters, approaches Troi, and bites her cheek.

Both Troi and Worf are taken to sickbay, and Crusher quickly notices the changes. When Ogawa adds that more of the crew are experiencing symptoms, but while some are also finding the temperature too cold there are others who have developed fevers, leading Crusher to conclude that something is spreading around the ship. She then turns her attention to Worf who is completely unresponsive, and notices something else: he has swellings under his jaw that appear to be venom sacs. They prove to be just that as Worf suddenly sprays venom in Crusher's face, then flees sickbay before he can be captured.

In the observation lounge, Ogawa reports that she got Crusher into stasis before she became paralyzed by the venom. She will require reconstructive surgery, but Ogawa believes she will be all right. However, there is still the problem of the mysterious illness affecting the crew. Barclay reports that the venom that affected Crusher has been found in other parts of the ship, including at the ruptured plasma conduit seen earlier. Riker admits to his inability to think straight; he can't think properly when La Forge reports on having trouble locating Worf on sensors. He dismisses the senior staff and tries to send a subspace message to Starfleet concerning their problem, but finds himself unable to recall the codes required.

Act Three

USS Enterprise-D adrift with shuttle approach

The Enterprise adrift

"Captain's Log, supplemental. Commander Data and I have recovered the stray torpedo after a three-day search. We are en route back to the Enterprise."
Picard and amphibian Troi

"Deanna?"

Picard and Data are a little puzzled to not be able to locate the Enterprise. A quick search locates the ship, visibly adrift. Upon docking, they ascertain that the ship's power systems are down, environmental systems are configured strangely, and where there should be over a thousand humanoid lifeforms there seems to be a near-equal number of myriad creatures. Some of the characteristics are inconsistent with those of the known crew, such as casting off skin like a reptile. They come upon Troi's quarters and discover her in her bath tub, having somehow developed into an amphibian-like creature. It is their first clue that the crew is undergoing unusual changes.

Dern corpse

Data and Jean-Luc Picard discover Ensign Dern's body

Seeking to stabilize the ship, they then go to the bridge, finding it in shambles, with a dead Ensign Dern at the conn (from what appears to be an animal attack), his spine fractured in three places; he had also been affected, but was killed before undergoing any significant changes. From the bridge, Data is able to note that the crew is still on board the ship but in a similar state to that of Troi. Many of them have been gravitating towards water (the aquatic lab) and plants (the arboretum). Picard is unable to restore power to the ship due to the entire power-transfer grid being damaged. Suddenly, they hear a noise coming from the ready room. There they discover Riker, now a brutish proto-Human, attacking the captain's aquarium (in which Livingston, the captain's lionfish, has also devolved into a jellyfish). When he charges them, Data stuns Riker with his phaser. Based on what they've encountered so far, Data announces his hypothesis that the crew is de-evolving.

Act Four

Troi and Riker are taken to sickbay for further analysis. Data, after analyzing Riker's DNA, discovers that a synthetic T-cell has invaded his genetic codes and has begun to activate his latent introns, a result of Crusher's treatment of Barclay. He explains that introns are genetic codes which are normally dormant; they are sequences of DNA which provided key physical and behavioral characteristics millions of years ago, but are no longer necessary. Counselor Troi's gill-slits and other amphibious characteristics, for example, are derived from introns which contain amphibious codes. Because introns can include genetic material from many different species over millions of years of evolution, it is possible that a wide variety of transformations is occurring among the crew. Since all humanoid life has a similar genetic pattern, the virus will work similarly on all non-Human lifeforms as well, and they will each be de-evolving to earlier forms of life in their homeworlds. He informs Picard that he has also been infected by the intron virus, and is now slowly de-evolving into an earlier form of primate.

Realizing that they do not have much time, they decide to act quickly. Since Data's computer in his quarters operates independently from the ship's computer and is probably still intact, they decide to go there in order to examine the situation further. Arriving at his quarters, Data notices that Spot, who has been expecting a litter of kittens, has finally given birth. A further search finds a reptile wearing her collar; they soon realize that the reptile is Spot and that the intron virus is capable of also affecting non-humanoids. Her kittens, however, do not seem to have been affected by the virus that has been plaguing the rest of the crew. Given that Spot's kittens are unaffected, Data and Picard conclude that the placental barriers and amniotic fluid that serve as a filtration system to protect the fetus in the placenta have probably prevented the intron virus from being passed on from Spot to her kittens. They decide that they probably can inhibit the intron virus by using the natural antibodies in Spot's amniotic fluid. However, in order for it to be effective on humanoid crewmembers, humanoid antibodies would be necessary. Recalling that Nurse Ogawa is expecting, they track her down to the arboretum. But before they can begin tracking her down, a failure in a warp plasma vent forces them to detour to main engineering so Data can program repairs. While checking on the warp core, Picard is frightened by the sudden appearance of Barclay, partially transformed into a spider. Data surmises that his terror at the sight (a result of the heightened sense of awareness found in small primates) is an initial symptom of Picard's de-evolution; they need to hurry.

They locate Ogawa (who is apparently partially de-evolved into a proto-Human) and Data begins to analyze Ogawa's fetus, confirming that it is not affected by the virus. He says that he can use her amniotic fluid as a template for a retrovirus which in turn would neutralize the synthetic T-cell and re-establish the genetic patterns of each host. While working on finding a way to most quickly address the situation, something pounds on the sickbay door. Life sign scans show something big, armored, and Klingon; it is Worf.

Act Five

A transformed Worf tries to force his way into sickbay. He appears to be seeking something or someone particular. Picard notices that the bite Worf gave Troi was not to hurt her but rather seemed part of a mating process, and that it appears as if Worf had come back for her. The situation becomes increasingly dangerous as an ever angrier and aggressive Worf almost breaks through the door. Data and Picard cannot just abandon Troi and the others in sickbay, but at the same time, Data needs to continue with his analysis of the amniotic fluid. Picard, who is beginning to experience the effects of the virus himself, suggests distracting Worf and luring him away from sickbay. He suggests extracting pheromones from Troi's sebaceous glands to lure Worf away from sickbay so Data can continue his work and the others are safe.

While Data continues work on the retrovirus, Picard leads Worf on a chase through the Enterprise's corridors until becoming cornered at the ruptured warp plasma conduit La Forge and Barclay had been repairing earlier. Picard improvises, sitting upon the insulated access panel and using the bypassed conduit to send electricity through the Jefferies tube, knocking out Worf. At that moment, Data reports that he has completed the retrovirus. It will make the introns in the crew dormant again; at Picard's consent, he floods the ship with a gaseous form of the new virus, turning the crew back to normal.

In sickbay, Barclay nervously asks Dr. Crusher if all this was his fault. She states that actually it was her fault for having activated a dormant T-cell which, in turn, activated all dormant T-cells (including the introns). She suggests naming the virus after Barclay, calling it the Barclay's Protomorphosis Syndrome. Jokingly, she tells Troi that Barclay not only devolved into a spider, but also had a new disease named after him. Troi sighs, realizing that she better clear her calendar for the next few weeks.

Production

  • This is the only episode of the series directed by Gates McFadden (Beverly Crusher), and the first episode of Star Trek directed by a female cast member. The next episode directed by a female cast member would be Roxann Dawson when she directed Voyager's "Riddles" six years later.
  • It was written into the script that Gates McFadden's character, Beverly Crusher, would be severely disfigured by Worf. She was promptly put into stasis to prevent the injuries from worsening. The absence of Dr. Crusher from much of the episode gave McFadden more time to spend directing the episode. (Star Trek Encyclopedia 2nd ed., p . 92)
  • Michael Westmore described his work in this episode as proving to be his greatest challenge. "Everybody mutated – Riker became an Australopithecine, Troi an aquatic animal, Barclay a spider," he recalls. "We never would have been ready if the episode hadn't miraculously fallen right after Christmas. We worked through the holiday." (Star Trek 30 Years, pg. 47)
  • First UK airdate: 15 May 1996

Continuity

  • This is the first episode since her promotion that Counselor Troi is seen in command of a duty shift on the bridge.
  • This episode follows "Lower Decks" in which Dr. Crusher told Alyssa Ogawa that she'll support her promotion. Ogawa is seen as a lieutenant for the first time.
  • Toward the end of the episode, Dr. Crusher comments to Barclay that it is traditional to name new diseases after the first patient. This tradition, evidently, appeared after our own time period. Eponymous diseases have almost always been named for the first person to describe them in medical literature (Parkinson's disease; Down's syndrome; Marfan's syndrome; Kartagener's syndrome). Rare exceptions from our time include Legionnaires' disease (named for a group of people) and Lou Gehrig's disease (unofficially named for a famous – though not the first – sufferer).
  • The list of visible transformations include:
  • Coincidentally, Barclay mentioned that spiders never bothered him in TNG: "Realm of Fear" (also written by Brannon Braga).

Awards

  • This episode won an Emmy Award for Outstanding Individual Achievement in Sound Mixing for a Drama Series; it was also nominated for Outstanding Individual Achievement in Sound Editing for a Series and Outstanding Individual Achievement in Makeup for a Series.
