The Voyager Conspiracy

Seven of Nine, played by actress Jeri Ryan, takes the spotlight in this episode, in a story that explores the relationship between data and conclusions.

[1] Seven of Nine decides to increase the amount of information she receives from the ship's database by directly assimilating as much of Voyager's data as possible.

She uses evidence concerning possible spatial-warp technology developments to convince Chakotay that Janeway might be spearheading a Federation presence in the Delta Quadrant.

(Seven states that Seska impregnated herself with Chakotay's DNA but in Season 3, Episode 1, the Doctor reveals that Chatokay is not the father.)

[2] They point out a triple combination of acting by Jeri Ryan, interesting Seven of Nine plot, and real-world encouragement for depicting someone overwhelmed with information.

[4] In the book Star Trek: The Human Frontier they noted this episode as example of exploring a mental illness on the show, in this case they thought it was a depiction of schizophrenia.
