Dialogue before the quest start
I'm stumped today, warrior. There are good people who need to escape the city. The closest they can get is through Avenue of Death, but there are snipers overlooking the whole area. One kid told me that if you shoot a signal flare there, the snipers should let you pass through, in that particular spot. But who knows if the kid was lying? Maybe he's trying to lead us to death. How do we find out if it's true that the snipers will stop firing after the signal... I got a couple flares lying around, why don't you go check it out, eh?
Dialogue after completing the quest
So he was correct, it is the cease fire condition, I'll keep that in mind. You really put your head on the line, didn't you? I respect that.
