a mechanic wandering around sometimes screaming and shivering due to the mental illness he suffered when he was young.
having a father that's beating you across the toilet sink for taking his grapes without permission does have quite the effect.
worked as a mechanic before everything went to hell and even though he doesn't have that much in the shooting skills he can still manage and will take chances if he is requested to aid whenever a car is broken down.
spare parts? yeah he got them!
are they for free? no....
are they cheap? perhaps....depending on what you are willing to give for lets say...a battery? or perhaps you have a flat tire? and he is in need of food? perhaps you got a deal.
betray him? do that and he will not stop searching to bust up your vehicle or your head.
dont mind when he starts screaming and acts weird....he doesnt like when you remind him of how off he really is.
