Katie had reached for her arm as she stood, but she wasn't fast enough. Hermione's legs crumpled beneath her, and the sound her head made as it cracked against the table was loud even in the crowded shop.

"Hermione?" Katie was kneeling at her side, careful not to move her-- what if she'd hurt her neck? "Hermione."

No response. Side-Along Apparition was tougher even than the normal kind, but Hermione had to get to St. Mungo's. Katie wrapped an arm around Hermione's waist the best she could without moving her, succumbing to the ugly narrowing sensation of apparition. Whatever was wrong, Hermione needed a healer, and she needed one now.
