One of the Delaney sisters of Voyager's stellar cartography department, who appears with her twin Jenny in the Captain Proton holodeck programme in the episode Thirty Days.
Megan Delaney serves with her twin sister Jenny in stellar cartography aboard the USS Voyager. The Delaney sisters are mentioned from the first season onwards as the object of Tom Paris's matchmaking schemes, but they stay off screen for most of the series.
They appear in person in Thirty Days. Paris has cast them in his Captain Proton holodeck serial as the villainous Twin Mistresses of Evil, Demonica and Malicia, opposite himself and Harry Kim.
Kim confides that he is drawn to Megan rather than to her more forward sister, but, typically for him, he does little about it, and the sisters are not seen again.
