The Vault Dweller

Upon returning to Vault 13 by the end of the game, the Overseer is delighted that the Vault Dweller has survived everything the wasteland had thrown at them to not only save the vault, but all of New California as well. However, seeing how the entire journey has radically changed them and fearing that the eventual hero worship amongst the vault's younger dwellers will cause them to leave the vault en masse, the Overseer decides to exile the Vault Dweller from Vault 13 for the sake of their people.
