How odd... a space marine willing to show grace or mercy? I do be leave that is against your precious Codex rules my dear Mon-Keigh... Perhaps your Inquisition should talk to you about this apparent weakness you possess.
Ugh, another brute. *sigh* I suppose I have a moment to...entertain myself with what you Orks call battle. We of the Craftworlds don't call it such though. I can't seem to right the words...low enough to describe what you lot do.
Oh, another brute comes to the rescue? How adorable. I'm surprised you can stop fighting each other for a moment to focus on me. I'm almost impressed, yet somehow I have a feeling that I'm giving the Orks too much credit. We shall see on the field of battle, perhaps, which of us survives in our contest. Unless, of course, I have more important business to attend to.
It is not weakness to honor the good of the foe. Unfortunately for this boss the Orks are vile enough to not get a grace period equal to that I would extend to a fellow citizen of the imperium.
