I think the biggest thing that I don't get is how they didn't recognize everyone from Vault 32 was dead and were replaced by raiders. It's revealed all 3 vaults are interconnected and that 31 is full of Vault Tec execs asleep and that 32 was also controlled by 31. They do the trade every 3 years so surely Hank or someone should have realized that the raider party wasn't vault 32.
