It isn't clear if Lt. Genovese could have been part of the Voyager crew when it was trapped in the Delta Quadrant, and worked on the Prometheus, which was built after Voyager was stranded. However, it is possible Genovese made contributions to the Prometheus design or construction before he was lost, and was still listed on the plaque in absentia. He could also have been assigned to the ship before it was stranded in the Delta Quadrant, i.e. during construction or testing.
Either way we don't know so no use in speculating — Morder (talk) 10:20, September 30, 2009 (UTC)
