Charlie didn't know Stanley defended Mikey!
Although the audience knew Fletcher ordered the flogging, Charlie didn't know that. Wouldn't he have assumed the Captain reneged on their arrangement? Nobody told Charlie, "the Capt. actually tried to defend your brother."
Charlie's last-minute rescue of the Capt. and his wife seemed appropriate to the audience but only if Charlie knew the Capt. tried to defend Mikey.
By the way, (to those who were tired) y'all got the bit about the Captain's wife getting pregnant through the rape and delivering the spirit of the murdered fetus. Her dream made that clear.
Was I sleeping regarding Charlies POV?
