The side mission Guess Who I Saw Today in Fallout: New Vegas offers players an intriguing look into the struggles of the Nightkin residing in Jacobstown. Tasked with helping Doctor Henry investigate the mysterious stealth abilities of local nightstalkers, players must balance tactical exploration with delicate diplomacy. Successfully completing this quest requires navigating dangerous caves, managing companion dynamics, and making critical decisions about the future of the Nightkin community.
Starting the Quest in Jacobstown
To begin this quest, travel to the peaceful mountain retreat of Jacobstown located in the northwestern region of the Mojave Wasteland. Head inside the main lodge and locate Doctor Henry working in his laboratory alongside his assistant Calamity. Speaking with Doctor Henry about his ongoing research into Nightkin schizophrenia will initiate the mission.
Before heading out to investigate the local wildlife, consider recruiting Lily Bowen as your companion. Doctor Henry suggests bringing Lily along to help study the unusual stealth traits exhibited by the local nightstalkers. Her impressive combat strength and heavy weaponry make her an invaluable ally during the upcoming underground exploration.
Exploring Charleston Cave
Your main objective takes you north of Jacobstown into the treacherous depths of Charleston Cave. The cavern is populated by hostile nightstalkers, which can easily overwhelm unprepared adventurers. Having high combat skills or bringing suitable weaponry will help you clear out the pack efficiently.
Deep inside the cave system, search for a fallen Nightkin lying on the cavern floor. Near the body, you will discover a key item known as the Chewed Stealth Boy. Collecting this item provides Doctor Henry with the necessary evidence to advance his medical experiments back at the lodge.
Confronting Keene and Resolving the Crisis
Upon returning to Doctor Henry, he will initiate an experimental test using the Stealth Boy Mark II prototype on Lily. Shortly after the experiment begins, a disgruntled Nightkin named Keene will enter the room and demand the prototype's specifications. How you handle this confrontation directly impacts the safety of everyone in Jacobstown.
Players with an 80 Speech skill check can convince Keene to stand down and leave peacefully. Alternatively, you can hand over the prototype specifications or refuse his request, which results in an immediate violent battle against Keene and his followers. Defusing the situation diplomatically avoids unnecessary bloodshed and protects Doctor Henry's research setup.
Determining the Future of the Experiment
After resolving the conflict with Keene, speak with Doctor Henry to determine the final steps of his research. You must decide whether Lily should continue wearing the prototype device to help cure her fellow Nightkin. Each choice carries distinct consequences for Lily's psychological stability and long-term well-being.
Passing a high Science check allows you to recommend a safer testing method using nightstalker brain tissue instead. You can also advise Doctor Henry to halt the experiment entirely or allow Lily to continue wearing the device. Completing this conversation finishes the quest and secures your rewards while shaping the narrative fate of Jacobstown.
