Additional Information

Tarn is a technician on Galactica.

Tarn is selected for a scout mission to Kobol (Kobol's Last Gleaming, Pt. I). When his Raptor is attacked by Cylon forces, it crash-lands on the planet, leaving him stranded on Kobol with the rest of the surviving team.

Tarn is sent back to the crash site to retrieve a medkit for the critically wounded Socinus, accompanied by Chief Tyrol and Cally Henderson. On their way back with the medkit, the three are ambushed by Cylon Centurions.

Tarn is caught in the open and fatally wounded, despite Chief Tyrol's efforts to rescue him from the line of fire (TRS: "Scattered").


  • When Seelix and Tarn first appeared in the season 1 finale, they were originally just generically named "Technician #1" (Tarn) and "Technician #2" (Seelix). However, Aaron Douglas, who plays Chief Tyrol, saw potential for the two characters, and after consulting together, they came up with names for the two characters. Douglas then just inserted their names into his lines on every take. So by the season 2 premiere, the credits officially started listing them with these names. Tarn died in the season 2 premiere, but Seelix ultimately becomes a recurring character in season 3.
