Hilde: Why don't you think of me as an enemy? I'll never let you destroy the Lunar Base.
Duo: I hate to say this, but you don't have the skills to be my enemy. So it's foolish for someone like you to even bother risking your life against me. But you know, you remind me of just how reckless I was when I went down to the Earth to fight all on my own.
Hilde: Don't patronize me!
Duo: In fact, we're both foolish. A soldier can get killed at any time. We'll see lots of friends in the colony lose their lives. Let's just live out our lives believing in the paths we've chosen. You've got to be at least that foolish to make it as a soldier.
