Keene

 is a rather surly Nightkin inhabitant of Jacobstown, initially found in Jacobstown Lodge.

Background
Keene is an influential Nightkin in Jacobstown in that for reasons unknown he has a pull on other Nightkin, attracting other Nightkin to the settlement and keeping the others from leaving. Marcus claims that Keene is very impatient and speaking with him will give you a good idea of just how impatient, not to mention irritable, he really is. Eventually, his impatience towards Doctor Henry's cure for Nightkin Schizophrenia causes him to attempt to take the Stealth Boy Mk. II, so they can see how it works and upgrade all stealth boys they find as they roam the Mojave doing unjust deeds.

Interactions with the player character
Keene actively shows displeasure when speaking with the Courier because he doesn't like being seen by humans (all nightkin don't like being seen by humans). After discovering the source of the Nightstalker mutations and testing the unstable Stealth Boy Mk. II on Lily for Doc. Henry, he and two of his Nightkin followers arrive to take the Stealth Boy Mk. II so they can leave Jacobstown, assimilate the Mk. II and upgrade any stealth boys they find. Keene can be dissuaded and the situation solved peacefully with a speech skill of 80. Otherwise, he will attack and you must kill him. Marcus claims it was probably inevitable and that it will be hard to attract more Nightkin to Jacobstown, and even harder to keep Nightkin already there from leaving. This has a significant post-game impact which is explained in the Fallout: New Vegas endings
