"Chorus still needs you Miss Kimball. So...when you die, you had better be damn sure that those you leave behind can carry on without you. ...I know I am. This is General Donald Doyle... signing off."
Donald Doyle

"It was actually Doyle who made me realize something that I've never thought of before. There are so many stories where some brave hero decides to give their life to save the day, and because of their sacrifice, the good guys win, the survivors all cheer, and everybody lives happily ever after. But the hero... never gets to see that ending. They'll never know if their sacrifice actually made a difference.They'll never know if the day was really saved. In the end, they just have to have faith. Ain't that a bitch."

"You can't. Impossible, but, Caboose! I did make the door because friends, best friends should be able...able to say goodbye."
