guys i met uncle leo and all he did was give me a pre-war business shirt and where supermutants are made....is there anything else he does?
You robbed Uncle Leo? How dare you, he's one of the nicest NPCs in the game!
The thing about Bethesda games like FO3 or Oblivion or Morrowind, is that there is not necessarily a "for" for everything. In real life you don't get something from everyone you meet, and not everyone in the world is there to do something with you. So sometimes it's like that in Bethesda games. Somethings are just there, since the world isn't necessarily about your character. And some things are just inexplicable.
