Serina and Apollo quickly fell in love and were married (sealed) by Commander Adama in the subsequent two-part episode "Lost Planet of the Gods". As after the destruction, Serina volunteered to become a shuttle pilot. When a strange disease incapacitated most of the fleet’s fighter pilots, she and all other shuttle pilots were trained to fly a Colonial Viper, despite Apollo's strenuous objections. The first space combat with the almost untrained shuttle pilots against a small Cylon outpost was won with no losses. While accompanying Adama and Apollo during the exploration of Kobol, Serina was shot by a Cylon centurion in an ambush and later died with Apollo at her side aboard the "Galactica." After her death, Apollo attempted to bury his grief over the loss by accepting as many high-risk missions as he possibly could, leading Lieutenant Sheba to accuse him, in "The Hand Of God," of having a death wish.
