Dialogue before the quest start
Hello, soldier! He who has the information is the victor. You want peace to win, don't you? So it's time to find some information for the good guys. A company was laundering money in the car dealership. Find any data on them that might be useful. My man managed to get a copy of the key to the office. Here you go. The problem, though, is that the entrance to the section itself is also locked, and we haven't been able to find that second key.
Dialogue after completing the quest
This information would be good leverage in the negotiations. It turns out that someone with the nickname Kaban, Hog in English, was operating there, but after some unknown events, he disappeared. A sincere thank you from the Blue Helmets!
