I don't think I like that episode.
Because of an abusive religious father and that Charles threatened to give Laura a whipping for walking along the creek and searching for notes in bottles all day and making him upset. I thought he would never hit her.
How very serious/extreme. And how morally family/child-friendly and controversial, I think.
No wonder some episodes are rated-PG and one of them (Sylvia) is rated-12 while the rest is rated-U.
