I don't know ?

Also, tuberculosis is a sickness where only few of the infected get sick and actually have latent tuberculosis. So Micah could have had TB and never even noticed (and also not infected no one). Additionally, how could Arthur have known that coughing on people infects them? Remember, this takes place 125 years ago, and Arthur is not exactly an educated guy ("German?! I can barely speak English").

He learned reading and writing from hosea and dutch so yeah that makes sense.

Reading and writing basic stuff

@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.

I really should've listened in Health class....

no honor amongst thieves...

Bruh fuck Micah, nobody cares about him, he should've died before ze game even started.

"When you fall, there'll be a party."

There was more than definitely a party

@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
