Newly Human
Being inspired by the books and tapes is one thing. Doing something because the books and tapes say so is another. In the first season, Joyce often refers to her books and tapes as rules for parenting rather than suggestions.
So, the other characters are allowed to have flaws & make mistakes, but not Joyce? Who, for the record, does NOT have full knowledge of the situation until the end of S2. I think she does indeed grow as a character and parent as she strives to understand Buffy's situation.
