The idea of Hansel making weapons with Booker and Sam has been Grade A. He's like Clint in a lot of ways, only more grumpy, and has no patience for the shit going down. Unfortunately for him he's kind of perfect for the atmosphere.
While I understand he isn't really the socially social type and would rather keep to he and Gretel's business and doing all he needs to then wanting to be left alone (lord knows thats my problem with Booker) like with the critique on Michonne I still want to see more. Throw his ass out there. Get him going. MORE. WERK.
