A Maquis survivor and the recently married wife of Michael Eddington, whose coded message about missiles is really a plea for rescue after the Dominion destroys the Maquis colonies.
Rebecca Sullivan is a member of the Maquis who appears in Blaze of Glory, played by Gretchen German.
In 2373 Starfleet intercepts a message, addressed to Michael, announcing that cloaked missiles have been launched at Cardassia. Benjamin Sisko takes the imprisoned Eddington out of his cell to stop them, only to learn at Athos IV that there are no missiles. The message was Rebecca's signal that the last Maquis survivors had reached their fallback position and needed evacuation. Eddington had married her shortly before his capture.
Rebecca escapes with Sisko and the other survivors aboard a runabout while Eddington stays behind to hold off the Jem'Hadar, dying in the firefight that covers their retreat.
