When Cackle found out that Mildred told Ethel that she was her niece she punished both girls. Uh bitch Mildred is keeping your damn secret so what's up with the harsh punishment? They were banished to their rooms for the rest of the year or whatever. The whole revising thing amuses me. Nope I never did that. I think that's just fancy British speak for studying. I didn't really do that either. Well maybe a little bit. Mildred clearly doesn't want to study so she decides that Cackle isn't really Ada Cackle. So she heads off to the cottage to see what's going on.
I get why Ada gave that harsh punishment since she has a major secret to hide. If she let Mildred off Ethel would just get more suspicious and desperate to find out what's going on with the scroll. While Mildred goes off to the cottage Ethel gets into trouble herself. She finds the scroll which tells her that Agatha is really the eldest. Could you be a dumber bitch? I guess it was clever of her when she let Scarlet and Agatha in. Uh how did she unfrog herself? I'm pretty sure she was a frog. Scarlet is helping Agatha and now she has Esmeralda's powers because she decided to sacrifice them instead of Ethel. God she's even a horrible sister. Face it Esmeralda you have a nasty little sister.
I guess Agatha was hiding when Ada came over so she knew her sister was on the loose. When Mildred went to the cottage the same bat showed up and it turns out that he's with Scarlet. Really? You named your bat Flappy? Seriously? Mildred shows up and think she's talking to Ada but she smartens up during the power relinquishing spell. She tries to get back to the castle to warn the others but Scarlet destroyed her broom so it took her all night to get back to the school. Since she left the school grounds without permission she got busted by Maude who betrayed her and Hardbroom sent her back home. I'm guessing at this point Hardbroom had no clue that Agatha was back in the saddle complete with powers that turned Drill into a freaking snail. Don't get this bitch angry.
