Bahnita was a loyal servant to Trager Retta. Bahnita communicated to Vala Mal Doran (Which Bahnita didn't know her real name) that Trager Retta died. This was a trap just to conduct Vala to the planet Inferra. The bounty hunter Shrike killed Bahnita after the latter talked to Vala. (SG1: "Vala Mal Doran 2")
