Navigating the sun-scorched wastes of Fallout: New Vegas often leads players to unexpected pockets of civilization, each harboring its own deep-seated problems. In the secluded community of Jacobstown, a peaceful refuge for mutant kind, a subtle crisis threatens to destroy their fragile tranquility from within. The side quest titled Guess Who I Saw Today tasks the Courier with investigating a bizarre affliction affecting the local Nightkin population, blending medical mystery with political tension. Unraveling this hidden plot requires diplomatic nuance, thorough investigation, and careful exploration of the surrounding wilderness.

Initiating the Investigation in Jacobstown

To begin this critical assignment, you must travel to the mountain resort of Jacobstown located in the northwestern region of the Mojave Wasteland. Once inside the main lodge, seek out Doctor Henry, a former Enclave scientist who is actively researching a cure for Nightkin schizophrenia. He will express deep concern over a sudden spike in stealth boy dependency and ask for your assistance in tracking down the root cause. This initial conversation officially adds the objective to your logs and sets your investigation into motion.

Before venturing out, it is highly recommended to speak with Lily Bowen, a friendly Nightkin grandmother who can join your party as a companion. Having her along provides valuable combat support and unlocks unique narrative depth as you delve into the psychological struggles of her people. Her personal connection to the unfolding crisis makes the ensuing journey much more meaningful for players looking to experience the full lore of the region.

Exploring the Perilous Charleston Cave

The next phase of the mission directs your party toward Charleston Cave, a damp underground network located just a short distance north of the resort. This subterranean labyrinth is filled with aggressive nightstalkers that utilize natural stealth to ambush unsuspecting travelers navigating the dark tunnels. Moving carefully through these caverns demands a high level of situational awareness to avoid being overwhelmed by the venomous pack beasts. Your ultimate goal is to locate a deceased Nightkin researcher tucked deep within the heart of the cave system.

As you fight your way to the lowest chambers, you will discover the body surrounded by hostile creatures. Searching the remains reveals a chewed stealth boy, which serves as the crucial piece of evidence Doctor Henry requires to advance his scientific experiments. Securing this item is necessary to understand how a specific mutant strain of flora is altering the behavior of the local wildlife.

Resolving the Medical Dilemma and Nightkin Politics

Upon returning to Jacobstown with the recovered device, you must present your findings to Doctor Henry inside his laboratory. He will propose a high-stakes experiment utilizing Lily to test a potential cure, which immediately triggers a confrontation with Marcus and a hostile Nightkin faction leader named Keene. Navigating this tense diplomatic standoff requires careful dialogue choices to prevent a violent outbreak from tearing the peaceful community apart. Players who wish to optimize their standing should weigh the long-term consequences of their scientific decisions carefully.

If your speech skills are sufficiently high, you can convince Keene to stand down and allow the research to continue without further hostility. Alternatively, you can choose how to configure the experimental parameters to balance Lily's mental stability with the survival of her species. Completing these final choices successfully concludes the quest, rewarding your character with substantial experience points and shaping the future of the mutant sanctuary.
