"Battlestar Galactica" Greetings from Earth (TV Episode 1979) - Randolph Mantooth as Michael

Captain Apollo : Michael, in our language Terra's a word sometimes used by an ancient race to refer to Earth. Have you ever heard Terra called Earth?

Michael : Yes, but it's also a term used to refer to the soil, other planets in our galaxy with similar environments. You have to understand, it's a common belief with us that we al stem from the same tree.
Captain Apollo : We'll check in with each other every few centons.

Michael : Apollo, just what is a centon?
Sarah : [atmospheric conditions making it impossible to survive] Another of science's great mistakes.

Michael : Sarah... I think it's time that you stopped blaming technology for all of man's sins. I think it's obvious that it's not the tools, it's what we did with them.

Sarah : Except for sending families to faraway planets to grow food on Terra, not realizing that children born there, can never come home.
Sarah : You don't have to worry about the Morelands. They didn't damage your ships. I did it.

Michael : What? Sarah, what in the name of God for?

Sarah : I wanted Apollo to stay. I thought he could survive here. Michael, I've been terrified of committing myself to you and many other people. Everybody I've ever loved... has been killed one by one. My father, my mother, my husband. I'm sorry...

Michael : Sarah, you had absolutely no right to try to force somebody to stay here. Especially Apollo. If it weren't for this man, we'd all be dead!

Randolph Mantooth: Michael
