According to Memory Alpha's original in Universe Timeline, the story sequence is: Behind the Lines : Revulsion : Scientific Method.


The crew is sitting in the mess hall for a celebration in honor of Tuvok, who is promoted to lieutenant commander. After the party Tom Paris catches up with B'Elanna Torres. The two haven't talked since the incident with the warp core three days ago, and Tom decides to make a move. B'Elanna confirms that she meant what she said when she confessed her love for him, and Tom accepts this with a kiss. Shortly after the party ends Voyager receives a distress call from a Serosian ship, whose only survivor is an isomorphic projection (a hologram) named Dejaren. B'Elanna and the Doctor take a shuttle to assist him.

In the meantime on Voyager, Harry works with Seven on improvements for the astrometric sensors. After his initial skepticism, Harry begins to appreciate Seven's work and gets a crush on her. On the Serosian ship, the Doctor talks to the fellow hologram, who is apparently unable to cope with the situation of being all alone on the vessel, while B'Elanna is doing repairs. The Doctor notices that Dejaren suffers from some kind of disorder but underestimates the hologram's deep-seated hatred for organic lifeforms.

When B'Elanna discovers the bodies of the crew members that Dejaren murdered, he attacks her. B'Elanna deactivates his systems, but he rematerializes once again and disables the Doctor's mobile emitter. B'Elanna eventually destroys the holographic matrix using a uninsulated power cable. Safely back in Voyager's sickbay, the Doctor patches up B'Elanna.

Errors and Explanations

Nit Central

  1. Chris Thomas on Saturday, December 05, 1998 - 8:00 am: When B'Elanna punches the hologram, it goes through him. But with other holograms, such as Worf fighting a computer-generated warrior, physical contact is made. This discrepecancy has cropped up a few other times, I'm sure. Just convenient to change the rules for sake of plot? Omer on Saturday, December 05, 1998 - 10:51 am: I think that the physical contact is optional. Richie Vest on Saturday, December 05, 1998 - 12:58 pm: I believe we learn in "Phage" that the doctor can change whether he is solid or not. Marten on Tuesday, January 19, 1999 - 9:41 pm: Yeah but the doc can't be half-transparant and half-solid, so *nit* he should've dropped the medicine bag he was carrying. Omer on Thursday, January 21, 1999 - 8:04 am: I think he probably can stay half holo and half real.
  2. Keith Alan Morgan (Kmorgan) on Monday, July 16, 2001 - 4:54 am: According to the dialogue this takes place three days after Day of Honor, so shouldn't it have been aired before Nemesis? Seniram 15:47, February 6, 2018 (UTC) Based on the stardates, the events depicted in Nemesis took place before this episode, and possibly between The Gift and Day of Honor
  3. If the HD Isomorph's body was just a projection, then why did the cable remain stuck in his body? Jwb52z on Monday, July 16, 2001 - 4:10 pm: KAM, if it is a SOLID hologram that doesn't have control of its matrix as far as solidity goes, anything stuck in it will stay stuck.
  4. Uncle Dick on Friday, July 20, 2001 - 12:30 am: Seven tells Kim that the Borg are not seductive. Funny, I could've sworn that the Borg Queen tried to seduce Data in Star Trek: First Contact. One could even venture to say that she tried to seduce Seven back into the collective in Dark Frontier. Captain Obvious on Thursday, January 30, 2003 - 9:34 am: While Seven's memories of the Collective are extensive, they're not complete, and it's unlikely she would have intimate knowledge of the Queen, especially if the Queen didn't want her to retain a specific piece of knowledge. And besides, Dark Frontier wasn't until the 5th season. This episode was in the 4th.
