Additional Information

Specialist Prosna is a deckhand on Galactica prior to the Cylon attack on the Twelve Colonies.

Decommissioning and Fall

A friend to Cally Henderson and Socinus, Prosna is late in wrapping one the flight deck crew's two surprise gifts for the retiring Commander William Adama — a photo of young Adama and his two sons, Lee and Zak found by Prosna in the Fleet archives. When Adama runs into them while working on his decommissioning ceremony speech, Socinus covers up their nervousness in hastily hiding the gift by complaining about the leaks they finished patching to the windows that cover the now-pressurized starboard flight pod, which houses a museum of relics from the Cylon War.

As with other members of the deck crew, he attends the decommissioning ceremony, and sits with Henderson, just behind Tyrol.

En route to their final berth, Prosna mops the hangar bay when Galactica is unexpectedly brought to Condition One. As he runs to stations, he comments to Henderson how the battlestar wasn't supposed to fight at all: Galactica destroyed her remaining battery munitions as part of her decommissioning ceremony earlier that day (deleted scene), and her last squadron of Mark VII Vipers left for Caprica as well.

Last Acts

Prosna is part of a damage control team when the port flight pod is struck by a nuclear missile in the battlestar's first Cylon sortie in over 40 years. Prosna calls for help to Tyrol, who manages to get to CIC's damage control station. However, the fires are advancing too fast, and Galactica's water mains are offline, leaving the D.C. parties to fight the fires with hand-held gear. Worse, the fires are coming too close to fuel lines for the battlestar; if the fire reaches them, the ship could be lost.

In CIC, Colonel Saul Tigh directs the venting of the specific frames in the port flight pod to space to quickly extinguish the fires. Tyrol manages to get a warning message to the D.C. party and Prosna, who warns as many people as he can that the compartment is about to be vented.

Prosna himself cannot or does not properly prepare for the venting action. He dies, possibly as part of the venting.

Henderson finds his badly burned body and holds him, crying, until Chief Tyrol helps her away. Prosna becomes one of the first 85 people to die on Galactica in the second Cylon War (TRS: "Miniseries").
