Pru vaguely registered that Mr. Rey had spoken to her. A boggart? She'd managed to get her wand out and point it at the creature. Fear had paralyzed her. It couldn't be a boggart. Boggarts weren't frightening. Theoretically they were, but when they'd learned about them in their textbooks she'd been distinctly bored. She looked over the top of her trembling hand at the thing — this was the most terrifying thing she'd ever seen. (Which, she realized belatedly, was exactly what a boggart was.)

Fortunately, Miss Woodcroft appeared and had seemed to take some control of the situation.

"N-no," She was unable to tear her gaze away from it to properly address the prefect, "I don't r-recall it! Stop!" She shouted as the thing took a step closer to her, the ring in its palm glinting in the torchlight, "Don't move, boggart!" At least knowing what it was - and that it wasn't actually real - offered her some small semblance of reassurance.
