According to Memory Alpha's original in Universe Timeline, the story sequence is: Revulsion : Scientific Method : Year of Hell Part 1.


Voyager approaches a binary pulsar, and Janeway decides to study the stellar phenomenon from a safe distance. Tom and B'Elanna neglect their duties over their love affair, and a very annoyed Janeway upbraids them. Janeway is on edge anyway because she is plagued by headaches for quite a while. Then Chakotay is taken to sickbay with signs of rapid aging, while Neelix develops traits of a Mylean, the species of his great-grandfather. The Doctor and B'Elanna scan the patients' DNA, which exhibit artificially generated tags that also emit a weak signal. As the two try to expose the aliens that are responsible and that must be slightly out of phase, the Doctor's program is deleted from the mobile emitter and B'Elanna is knocked out. The Doctor contacts Seven of Nine through her audio implants and secretly meets with her on the holodeck that is free of alien activities. He modifies her ocular implants so she can see the intruders. They devise a plan to use the EPS relays to cause a neuroleptic shock in all crew members that would incapacitate the alien devices. But Seven doesn't manage to complete the work. When aliens show up in Tuvok's presence, she takes a phaser and exposes one of them. The alien woman is taken to the brig. She tells Janeway that they are just conducting scientific research for the benefit of their people, and that they could kill the crew in an instant if they were forced to. After the death of a crew member Janeway decides to act and steers the ship right into the range of the pulsars. The aliens try to escape, but one of their ships breaks apart. With the aliens gone, the mutations to the crew can be reverted. Tom and B'Elanna muse whether their love affair was just a result of the alien experiment.

Errors and Explanations

Nit Central

  1. Cableface on Saturday, December 05, 1998 - 12:16 pm: Just how did Chakotay become normal again? Sure, he ages unnaturally quickly, but he still ages. And yet he's fine afterwards. Does this mean that the doctor can reverse aging in anyone? Omer on Sunday, December 06, 1998 - 1:02 am: Stranger things have happened. Alas not often
  2. BrianB on Monday, July 26, 1999 - 1:21 am: The Doctor and Seven were in the holodeck hiding from the scientists. Doc wished to adjust 7's eye implant, her sensory nodes, so she can see them. He asks the computer for a type-4 micro-inducer and does the task. This is a holographic type-4 micro-inducer. Can it really function just like a holographic phaser with safeties off? Wouldn't his efforts disappear when she leaves the holodeck? Maybe it can work like a real tool and so there's no nit. I think the doctor should've gotten the micro-inducer via the replicator, or just use a very fine screwdriver like Janeway did in Hope and Fear. Stephen on Monday, January 24, 2000 - 12:57 pm: When the doc asks for a micro-inducer the computer sent him a real one not a holographic one. Plenty of real things can be brought into the holodeck. Jocko on Monday, January 24, 2000 - 4:33 pm: Sure it's a real micro-inducer, until you try to remove it from the holodeck. Just like the tables, paintings, people. cableface on Wednesday, January 26, 2000 - 2:19 pm: Even if it was holographic, that doesn't mean the effects would disappear. Let's say a drunken brawl breaks out at the holodeck resort, and somebody "bottles" Neelix (without the hindrance of safety interlocks of course).I doubt the cuts and bruises would disappear when he walked out of the holodeck.
  3. KAM on Tuesday, July 17, 2001 - 4:32 am: In the NextGen episode The Next Phase, Geordi, Ro and a Romulan were coming and going from the Enterprise because they were out of phase. In Phantasams interphasic creatures had infested the ship and were literally eating the crew alive. Now, given these two incidents, don't you think that Starfleet would come up with some kind of sensor to detect phased organisms? Granted Voyager was able to detect the presence of the Voth in Distant Origin, but, as this episode shows, a regular scan for phased organisms is not a normal procedure. (The cloaking device from The Pegasus had the ability to phase objects. Would it be so hard to adapt it to detect phased objects?) It was probably deemed impractical.
  4. B'Elanna takes off her comm badge, then folds her hand over it, So why didn't the badge chirp when her fingers touched the front? It couldn't be that taking it off deactivates it because there are many times when comm badges have been removed and still active. Jwb52z on Tuesday, July 17, 2001 - 3:32 pm: You have to actually press it for it to activate.
