@Nilpferd218 In the trivia section on Micah's page it mentions that Micah seems to have respiratory problems, constantly snorting, clearing his throat, and coughing.
So maybe your right and Micah actually did have a form of non-fatal tuberculosis which would be really ironic.
@1930s old timer Micah's just the snake that slithers in when Dutch was in a bar in the middle of nowhere. Wasn't really even part of the gang, just Dutch's weird friend
