Fallout TV Series season 2 teaser for a trailer

[Tenebris]

It's funny that they could have solved all these plotholes by just putting the new vaults near where Shady Sands actually is, which is maybe what they planned originally. That would raise the question of why the Overseer didn't send you to those as well as Vault 15, but that could be explained by it being a secret vault the others don't know about. But of course they wanted the big reveal of the LA ruins in the first episode so the audience could point at the screen and say "I recognise thing!", so they moved Shady Sands across the map and made the Master stupid.

it will still be a problem, the ncr in fallout 2 were trying to take vault for their technologies like 15 vault city and 13, so putting them around their capital is also stupid
