The next morning, Hagar insists the silver wards are holding and that nothing can cross silver. Fern still fears Miss Parcae and, that night, keeps watch with Holly and Zinnia, worrying about what would have happened if Fern had accepted Miss Parcae’s offer and how they could ever send Miss Parcae away without condemning Holly back to her abuser. Dawn comes with no sign of the witches, and Fern clings to the idea that soon she will leave Wellwood and become “Neva” again after giving birth.

On a sweltering Laundry Day, the heat feels unnatural and oppressive as new girls Petunia and Violet arrive to replace Flora and Daisy. While the girls struggle through the work, storm clouds finally gather, lifting everyone’s mood with the promise of rain. The sky darkens, the wind rises, and Hagar orders the girls to keep moving as the storm stubbornly holds without breaking.

Without warning, windows shatter and what begins like hail becomes a violent rain of stones: jagged rocks and gravel crash into the yard, smash glass, and injure girls, including Tansy and Willow. The girls scatter for cover as Fern pulls Zinnia toward safety; Clem shelters a crowd in the Smoke Shack while the tin roof is battered and screens are shredded. Miriam and Hagar drag Willow toward the Barn using umbrellas that are quickly torn apart. Overwhelmed, Fern screams repeated apologies and pleas for it to stop, and the stone-fall abruptly ends.

In the aftermath, Mrs. Deckle and Diane ferry injured girls to the hospital, and Nurse Kent treats others in the Barn; Laurel remains hospitalized overnight. As the girls speculate about “natural” explanations, Fern, Zinnia, and Holly recognize the attack as supernatural and try to find Hagar, but Miriam avoids telling them where Hagar is. Soon Hagar returns driving Miss Wellwood, who appears thinner and weak, and police arrive to investigate by searching the woods.

Miss Wellwood forces the girls to clean up shattered glass and then orders Hagar and Miriam to remove the horseshoes over the doors, undoing the protective wards. In assembly, Miss Wellwood calls the stone-fall an attack by “hooligans,” claims Laurel is only under observation, and implies she knows where the stones truly came from before dismissing the girls. At dinner, Miss Wellwood announces the sheriff found a nearby “hippie” encampment and accuses the girls of sneaking out and bringing “diabolism and superstition” into her Christian home; she searches rooms, confiscates contraband, and threatens punishments and parent calls. Fern confronts Hagar for a plan, but Hagar—polishing the dug-up silver and admitting Miss Wellwood noticed missing pieces—can only repeat that she does not know what to do.
