Constance Barnes was a female Human and a Counselor in Starfleet in the 2360s and 2370s. In 2366, when she was a trainee counselor, Barnes was assigned to the USS Saratoga. Just a short time later, the Saratoga engaged the Borg at Wolf 359. Although she did not meet many of the Saratoga crew, she became attracted to Benjamin Sisko. After the Saratoga had been damaged by the Borg cube in the battle, Barnes discovered Jennifer Sisko, who had been crushed by falling debris but was still alive. Conflicted by her feeling for Sisko and her terror of the moment, Barnes did not help Jennifer.
