In this episode, Tom Zarek and Felix Gaeta trigger a bloody uprising on the Galactia. We don't get to see very much of the fighting, but as Apollo and Starbuck make their way around the ship, we see a shitload of expended rifle cartridge cases.
First off, I have to love Starbuck. When it comes to fighting, she is one cool woman. Apollo had been captured by a group of rebels; when she ordered them at gunpoint to release him and they refused, she shot two of them them and then said: "I can do this all day."
(Those pistols don't seem to have much killing power for the ball round. I don't know what they are, but they definately aren't .45s.)
Gaeta's forces took Admiral Adama and Col. Tigh; who overpowered their guards and escaped. As the episode ends, it appears that Adama and Tigh are going to go all "Butch Cassidy" against a large group of Colonial Marines.
I don't see the uprising ending quickly, but I am reasonably sure that it will end with Tom Zarek fleeing in a ship or a small group of ships. Felix Gaeta will probably wind up with Starbuck either putting a bullet in his head or shoving him out an airlock.
Still, in my opinion, the best hour of TV during any given week.
