He's kind of like that crazy prepper/survivalist uncle who lives in the ass end of nowhere, has a homemade fallout shelter stocked to the ceiling with canned chicken and peach, sleeps with a combat knife under his pillow, and rants about the government and agencies whenever he gets the chance. The family still keeps him around because he sometimes does something useful.

Luke Smith, on the other hand, is already out in the desert building a shrine to Old Man Atom.
