Biwwy

Billy or Biwwy, is a 9-year old child in Little Lamplight in 2277.

Background
Biwwy, or Billy, is a young boy with a slight speech impediment, making it hard for him to pronounce the L and R sounds. He used to be on the scavenging team in Little Lamplight, but was recently kicked out of it because none of the other kids could stand being around him. He's still generally avoided by most and leads a slightly sad, lonely existence, lurking in the alcoves of the Great Chamber and playing with his Wazer Wifle.

Relationships
Biwwy (or Billy) doesn't seem to have any friends, as everyone finds him annoying, possibly because of his speaking disabilities and apparent hyperactive nature.

Other interactions
Biwwy (or Billy) wields a unique laser rifle called the "Wazer Wifle" which can be bought from him for 500 caps or 250 with a sufficient barter skill, or if you have the Child at Heart perk can be obtained for free.

Appearances
Biwwy appears only in Fallout 3.
