Battlestar Galactica, Season 2

[Following the Cylon ambush of Pegasus and the death of Commander Barry Garner (Pegasus's commanding officer).]

Adama:
In your opinion, off the record, what was Garner's flaw?

Apollo:
He was used to working with machines. Command is about people.

Adama:
Remember that, as you take command of "The Beast". Garner was my decision; his failures, my responsibility. Don't let me fail a second time. Congratulations, Commander.
