Explore the Charleston Cave

Make your way to the hidden cave on top of the hill behind Jacobstown. Here, you will encounter a couple of Nightstalkers as you progress further in the cave.

Continue moving forward until you reach the Nightkin corpse that contains the Chewed Stealth Boy. Take this item, and then leave the cave before fast traveling back to Jacobstown.

You Can Also Grab the Oh Baby Melee Weapon

In the same room where you find the Nightkin Corpse, you can also find a unique melee weapon lying on the floor called Oh, Baby.

Return to Doctor Henry at the Jacobstown Lodge and give him the Stealth Boy that you obtained from the cave.

Request Lily to Help With the Experiment

Speak With Keene When He Enters the Room

Refuse to Give the Prototype

Give the Prototype to Keene

Letting Keene get the prototype will also defuse the situation but Doctor Henry is going to be worried of what the mutants will do next.
