Trager Retta was a lover of Vala Mal Doran who died by Hypothermia.
Trager was indeed killed by the bounty hunter Shrike's freezing touch. Trager's funeral was done on Inferra, to which Vala was invited by Trager's servant Bahnita. Vala assisted Retta's funeral only to be captured by Stanley Truitt. (SG1: "Vala Mal Doran 2")
