Fern wakes to morning at Wellwood House with Holly pressed against her. The girls stumble through the usual routines, still dirty from the previous night’s excursion, barely functioning through breakfast.

During morning meditation, Miss Wellwood announces she knows someone snuck out through the front door and demands a confession. When no one speaks, Miss Wellwood declares the doors will be locked at night and begins calling girls to her office for individual questioning. Fern, Zinnia, and Holly avoid being summoned, and Rose signals them to meet later in her attic room.

In Rose’s attic, Rose reveals Miss Wellwood questioned her and confiscated her hidden cigarettes, but Rose did not give anyone up. Rose argues that Miss Parcae’s “help” amounted to infected cuts and an unreadable book, and insists the girls must save Holly themselves. Rose pushes to use the one proven spell—Turnabout—possibly against Reverend Jerry and other men who hurt them, even if it becomes revenge as much as rescue.

While they argue, Fern notices the cover of How to Be a Groovy Witch and realizes the model resembles Miss Parcae, down to a distinctive wart. When they check inside, they discover the book has changed: a new glossary has appeared with specific instructions for a “Sign of the Rending of the Veil.” The shifting contents convince them something supernatural is happening, and the book is not what they thought.

Rose calls the book “power” and declares it their only way to help Holly. Zinnia refuses to be involved and storms out despite Rose’s threats. Fern finds Zinnia in the music room, where Zinnia admits the book’s change proves magic is real—and that realization terrifies her. Zinnia warns that witches in stories always trap people once they are “in too deep,” and she resolves never to be in the same room with the book again, shutting Fern out as she plays a silent piano.
