Marowski was once a renowned drug kingpin and party maniac, up until around 2280, when he decided to settle down and run his drug production operations from the Hotel Rexford in Goodneighbor. Marowski also owns a chem lab south of Goodneighbor, in the Four Leaf fishpacking plant.
Diamond City Blues - Upon completion of this quest, should Trish or Nelson Latimer survive, Marowski will confront the Sole Survivor about the busted deal and demand that they pay him 2,000 caps, though this can be negotiated to a lower price. Failing to do so will cause a group of Triggermen to occasionally spawn in Diamond City and attack the player character. Alternately, if the quest is completed and Nelson Latimer is killed, his father Malcom Latimer will confront the Sole Survivor and demand answers about his son's death. If a Charisma check is passed convincing him that Marowski was responsible, Latimer will hire the Sole Survivor to assassinate Marowski.
