Billy is a child who was caught stealing. Rather than imprison or exile him, the Hub police put him in the care of Dan to put him on the straight an narrow.[1] Billy is a hard worker and tends to the brahmin well, though he has to use the spear to make them do his bidding.[2]
"What's a brahmin? You must be joking. Why they're one of the major food sources and forms of transportation around here. They haul the caravans. Dan says this is a really important job, but it's the Bone."
↑The Vault Dweller: "{162}{}{Why the hell where you yelling at that poor kid?!}" Dan: "{168}{}{Look, that kid was caught stealin'. The police put'm in my care ta straighten'm out.}" The Vault Dweller: "{173}{}{That still doesn't justify the way you're treating him!}" Dan: "{175}{}{I may not be the best role model in this damn city, but I'm the only one who cares and is willing ta try to help. What have ya' done to improve society?}" (DAN.MSG)
↑The Vault Dweller: "{113}{}{What's the spear for? Are they dangerous?}" Billy: "{132}{}{Dangerous? No, not really. They can give you a really nasty bite, but they're pretty cool. They fart and burp a lot. I don't know why.}" The Vault Dweller: "{133}{}{So what's the spear for?}" Billy: "{135}{}{Oh, they can be awfully stubborn when I want them to do something. I just gently stick them to get them to move around . . . plus I don't want to get too close; they sometimes kick. }" (BILLY.MSG)
