Star Trek: Voyager, "Equinox Part II"
Star Trek: Voyager, "Equinox Part II". #221, 22 Sept. 1999; Season 6, episode 1.
In her brief annotation in Cinefantastique 33.5, Anna L. Kaplan quotes episode writer Brannon Brana's reference to Seven of Nine as "conscience" to Captain Rudolph Ransom, the human CO of the USS Equinox. Since Seven of Nine is a former Borg drone, her acting as a conscience is of interest.
