Neelix is confronted by the Haakonian scientist named Ma'bor Jetrel, the man responsible for creating the Metreon Cascade, a device that was used to annihilate a major portion of the Talaxian race, including Neelix' own family. Jetrel is allowed to board Voyager when he asserts that Neelix will soon fall ill from long term affects of the Metreon Cascade device. Tempers flare between the two, with Neelix instantly distrusting the man who murdered his loved ones. Ultimately, Neelix must discover Jetrel's true motive for being on board Voyager, before it is too late.

• The Metreon Cascade killed Neelix' family (his mother, father, 3 brothers, and 3 sisters) in 2355. Neelix' family lived on Rinax, the moon of the planet Talax.
  
• Jetrel dies of metremia, but not before Neelix gives him forgiveness.
