Grinwhite

Phoenix Tavern
If you talk to him anytime, he will reply:


 * Grinwhite: Those rag-gatherers! Those scum-suckers! A Quickfoot thief snatched my signet brooch while I was inspecting some potions. Jorasco's badge in a trashmonger's hands! What a humiliation! If you can get it back, I'll pay you a thousand... no, a hundred... oh, let's just say an 'ample' number of gold pieces. Are you a coward, or do you want the job?
 * You: Start couting my gold. I'll be right back
 * Grinwhite: I'll count your gold when I see my brooch again. Now get moving! (Bestow quest)
 * You: I'm no coward, but I do hate sewers.
 * Grinwhite: Lazy and shiftless, eh? A common affliction among your class. Mark my words, you'll be stealing for your own supper before too long. (Walk away)

Talking to him after acquiring the quest, but before completion, will make he say:


 * Grinwhite: Where is it? Did you find my brooch? I'm not interested in your excuses!

On completion of quest, he will tell you the following:


 * Grinwhite: What happened to my brooch? It's filthy! It's ruined! It's nothing but trash! I won't pay good gold for rubbish. You'll just have to be satisfied with whatever reward I dig up for you. And you can keep that piece of junk too! OIr better yet, throw it away. That's what I'd advise!
 * You: Is that so? You'll regret cheating me, Grinwhite.

After completing the quest and take the reward, if you talk to him again, he will reply:


 * Grinwhite: A month's pay, drowned in the sewers! Well, at least you killed the fools who stole it from me. They struck a hard bargain for their useless lives.
