S1E4 · Act of Contrition

Complete story — includes the ending

After many of Galactica ' s pilots die in a deck accident, Starbuck begins training new ones. She is however conflicted as she still feels guilty about the death of her fiancé and Commander Adama's son Zak two years ago — being his instructor, she unfairly passed him in the basic flight test; this led to his death as he didn't have the necessary flight skills. Being overcautious, Starbuck washes out all of her new trainees after their first day of training. After she confesses to Adama about her role in Zak's death, he feels hurt and angered, but orders her to reinstate the trainees and resume the trainings. During another exercise, Starbuck and her trainees are attacked by a squadron of Cylon Raiders; they defeat the Cylons, but Starbuck's ship is heavily damaged and crashes to the nearby moon; and she ejects into the moon's atmosphere. In Galactica ' s sickbay, Roslin visits doctor Sherman Cottle who confirms her diagnosis of advanced breast cancer and agrees to help procure "Chamalla" extract for her as an alternative treatment. On Caprica, Helo and Sharon find a fallout shelter with food and medical supplies.
