The depth of the relationship between Adama and Starbuck is deepened when she kicks Colonel Tigh’s butt at space poker, resulting in the drunken executive officer knocking the table over before getting punched by Starbuck. Later, a protective Adama makes sure Tigh won’t file charges against Starbuck for striking a superior officer. We later get some context for their father/daughter relationship (which is how it’s described in the original miniseries script, by the way): Starbuck was engaged to Adama’s son Zak before the younger man died in a flying accident, leaving the Commander without one of his sons, though Starbuck tries to fill that emotional gap.
