Dialogue before the quest start
Young man, I cannot stand aside on this one. I'm aware that you are now working with this so-called Skier. This disreputable man pursues completely lucrative interests and that is a matter of great concern to me. Especially all this story with secret experiments on a substance that you call the yellow chemical. The substance is extremely dangerous, and I have a major request for you, could you give up the coordinates of the chemicals to me? Yes, I'm aware of all the details of your adventures with the Skier. I would come up with good payment for that. Again, this is all just for the sake of our people.
Dialogue after completing the quest
Wonderful! I can already see how that nasty grin fades from the Skier's face. He will definitely be unhappy with you, but you acted for the good of the civilian population, so there is no need to be upset. Let this reagent be under the control of competent people, I will take care of the transportation. Your share, as agreed. You made the right choice.
