By the way, I wonder where the number Vault 31 for Twin Mothers posted in old VB leaks by kumquatq3 (
here) comes from. In the Twin Mothers design document, the vault is called Vault 29, the same as Harold's Vault in Fallout Bible. According to Fallout Bible,
No one in this Vault was over the age of 15 when they entered. Parents were redirected to other Vaults on purpose.
While this sounds suspiciously similar to Twin Mothers (where there were adults initially, but they were old and quickly died, leaving the children to be brought up by Diana), it doesn't make sense for Harold to be from this vault, since he would have recognized his old home, as well as Diana when he came there before going to the Nursery. While most of Chris Avellone's stuff in the Bible is made up, this Vault is mentioned in the Timeline, which is mostly based on old design docs for FO1 and FO2 (that's also why it had many wrong names for places in the first version, like FSEF for West Tek - they were old names for those places in the original design docs). Therefore I wonder if the intention of the VB designers was:
1) Harold was from Vault 29 and Twin Mothers is some other Vault (31, as in the kumquat leaks)
2) Harold was from Vault 29 and it's the same as the Twin Mothers Vault
3) Harold was from some other Vault, and Vault 29 is the same as the Vault 29 mentioned in the Fallout Bible
4) Harold is from Twin Mothers, but he doesn't remember much about his youth after his mutation
Also, which name is more recent - Tibbets or Leavenworth?
