Probably Charles was happy he was helping her getting an education that in the future may pay off for the whole family, while Frances busted her ass off learning music and shiet to meet the family's expectations. That is how families work, but Netflix does not seem to understand that.

Not to mention that Charles Dickens' works are classics but no one has ever heard about her sister's accomplishments because whatever she did didnt have a social impact as big as her brother's. That is why he gets a statue and she doesn't. There was nothing to fucking see there until Netflix came up with this retarded PR stunt.
