One of the starting missions in the Santa Monica area is to find a ghoul named Mercurio. He has been badly beaten, and the item he was entrusted with has been taken. He will ask you to retrieve it. Now, if you go in and call him names, and tell him you will report his incompetence to the prince, when you return, he may be waiting for you with a knife. However, if you cover up his incompetence, he may be able to get you better deals on weapons and other items as you progress into the game.​
