I just finished this quest and Zho died en route, While fighting Pei. I was still able to finish.
Lame quest. 90% of the time, Zho and Sujun will die, making the quest ready to do again.
Funny Dialogue[]
This quest has quite possibly the funniest Dialogue in Guild Wars! I'm thinking Sujun is insane. Pay Attention to the dialogue when doing this quest.
