Why was it necessary for Olive to apologize to Rihannon? From the beginning it just seemed as if Rihannon was not a good friend. She didn't listen to Olive and basically badgered her into the lie that started the whole thing. She then went on to, I assume, gossip behind Olive's back, because she reported back some of the rumors she's heard about her. Rihannon even basically abandoned Olive and joined the mob that vilified her. I don't know, I just don't see Olive's need to apologize to such a friend.
