Ethel thinks it's Mildred's fault that Sybil is always following her around, so when Mildred insults Ethel's family during a lesson of broomstick flying, Ethel vows to get her own back. When Tabby falls off Mildred's broomstick, she is sent to her room with strict orders to make sure that the cat learns to properly sit on the broomstick. Mildred returns to her room and looks out the window, making another promise to Mr. Algernon that he'll have tea and crumpets again.
