Joseph (Fallout 3)

Joseph is the eldest resident of Little Lamplight. His little sister is Penny.

Joseph teaches the history of the world and Lamplight Caverns to all the kids who volunteer to learn. The player can sit in on Joseph's class by visiting the Little Lamplight schoolhouse in the mornings. If pressed during conversation, Joseph explains that he and his predecessors began by teaching survival skills to younger children, but they were able to recover some Holodisks from Vault 87's classroom at some point, and this provided them limited teaching materials. Over time, all access was cut off from Vault 87, and nothing new has been recovered in several generations.

Joseph is also the town barber, and can give the player a change of hairstyle.

Accessing Vault 87 through Joseph
If you rescue Joseph's sister Penny from Paradise Falls (see the Rescue from Paradise quest), you can ask Joseph about an old access door to Vault 87. Joseph will turn on a hackable computer terminal that can open the door. This approach saves the player a trip through the dangerous, Super Mutant infested Murder Pass.
