Throughout the cliffhanger Season 3 finale, "Crossroads, Part II", Tigh, along with Samuel T. Anders, Galen Tyrol, and Tory Foster experience snippets of hallucinatory music, that only they can hear, yet cannot grasp. As they are drawn to meet and the music becomes clearer in their minds (which turns out to be the Bear McCreary cover of "All Along The Watchtower"), a mental "switch" (as described by Chief Tyrol) is activated and gives them the revelation they are, in fact, Cylons. As the four come to terms with this knowledge and its consequences, the Cylon fleet attacks. Tigh orders the others to report to their stations and defiantly declares, "My name is Saul Tigh. I'm an officer in the Colonial Fleet. Whatever else I am, whatever else it means, that's the man I want to be. And if I die today, that's the man I'll be."
