My favorite Laura Roslin moment was this exchange between Tom Zarek and her after he has lied about successfully pulling off his coup:
TOM ZAREK: [over wireless] This is Tom Zarek, President of the Twelve Colonies. It's over Laura. Saul Tigh was killed attempting to escape. Bill Adama was tried and found guilty of his crimes. A firing squad executed him this morning. It's done, Laura. You want to think about the people of this fleet now, and surrender.With all due respect to Starbuck fans, Roslin was the woman you did not want to make angry.
ROSLIN: (with building fury) No. Not now. Not ever! Do you hear me!? I will use every cannon, every bomb, every bullet, every weapon I have down to my own eye teeth to end you! I swear it. I'm coming for all of you!
