A Starfleet security lieutenant posted to Deep Space 9 in 2369, whose arrival to safeguard a deuridium shipment brings him into conflict with Constable Odo.
Lieutenant George Primmin is played by James Lashly in two first-season episodes of Deep Space Nine. In The Passenger he is sent by Starfleet to oversee protection of a deuridium cargo bound for the Kobliad, and his assumption that he is in charge of the arrangements offends Odo so much that the constable offers to resign.
Sisko smooths things over and reminds Primmin that Odo knows the station far better than he does. The lieutenant makes amends by finding a hidden device planted to cripple the station's systems, and the two cooperate against the hijackers.
He returns in Move Along Home, where Odo is exasperated to find that Primmin has not noticed the senior officers are missing. He is not seen again.
