When did Charles have some real audacity for meddling in other people's affairs?

Some of the occasions are more warranted than others. I thought Charles had audacity in the episode where Mary was in the hospital and him and Mr. Edwards are digging the tunnels. Charles doesn't give a flying rip that the working conditions are unsafe or that somebody died and the others are on strike because of it -- even blasting right through the poor old man's funeral. Nor does he care that the boss is a hardass racist. Mr. Edwards has enough and goes to quietly leave and Charles PUTS HIS HANDS on Isaiah -- the man who tried to help him even though that wasn't his daughter!

Thankfully, Mr. Edwards knocks Charles flat on his ass but not even that is enough for Charles to get the message. In fact, Charles doesn't get the message until he nearly dies from those very same unsafe working conditions.
