Guard Jung

The Harbor
If you try to talk to him anytime, he will reply:
 * Guard Jung: Blast it! Where are the guardsmen the Harbormaster promised?
 * Guard Jung: The Bonebite kobolds are getting too bold... they'll attack Stormreach if we leave them unchallenged for any longer!
 * You: Harbormaster Zin sent me to help. I'll take care of your problem.
 * Guard Jung: You'll take care of it? Are you really that tough? Well... we'll find out.
 * Guard Jung: The Bonebite kobolds have a new leader... he's recruited Bugbear fighters and has some kind of big plan. I need you to find and kill this leader.
 * Guard Jung: And one more thing... (sigh) these kobolds stole my badge. I'd appreciate it if you kept an eye out for it.
 * Guard Jung: The Bonebite Hideout is just at the end of this alley here.
 * You: I'll come back when I'm done. (Bestow quest)

Talking to him after acquiring the quest, but before completion, will make him say:
 * Guard Jung: The Bonebite Hideout is right up ahead in this alley.

On completion of quest, if you have not found his badge, he will reply with the following:
 * Guard Jung: ?????????????????

On completion of quest, if you found his badge, he will congratulate you with the following:
 * Guard Jung: Thanks for getting my badge back! One of the other guards spent a week in the stockade for losing his.
 * Guard Jung: And you dealt with the Bonebite's new ogre leader too... well done!

After completing the quest and take the reward, if you talk to him again, he will reply:
 * Guard Jung: Since you raided their hideout, the Bonebite kobolds have been in disarray... we'll exterminate them if they make any more trouble.
 * Guard Jung: Fine work!
