"Let me tell you something. I've had to watch a lot of kids be put into body bags. They're covered with flags and they float out that airlock. You think I don't understand his feelings towards his men? Sometimes terrible things have to be done. Inevitably, each and every one of us will have to face a moment where we have to commit that horrible sin. And if we flinch in that moment, if we hesitate for one second, if we let our conscience get in the way, you know what happens? There are more kids in those body bags. More kids floating out that airlock. I don't know why... but I have a lot of faith in you. And I want you to promise me that when that moment comes you won't flinch. Do not flinch."
--Admiral Helena Cain (Resurrection Ship, Part II)
