Dr. Joan Watson:  It 's not how I pictured prepping . I mean , when you say survivalists , I see ... bearded guys wearing gas masks digging holes in their backyards to build shelters .
Sherlock Holmes: That 's the garden variety prepper . The Keep caters to a uniquely vile subset , the wealthy prepper .

Which , _ one _ could argue , would n't be the worse thing in the world .
