well i don't think "coward" is the proper term. in fact he dueled you: he's just a perjurer
Then maybe you should learn what the word means.
What do you call someone who runs away from a problem, refusing to go through with what he agreed on? I call that person a coward and a piece of scum.
I already told Quatal once yesterday when he wanted to make "peace"(implying there was a war between us), you're not worth anything to me, and I don't really care if you pay me or not, but don't think for a second that you'll ever have my respect. You don't deserve any, and even less now.
