Hermione had a choice to make in that moment. She could either rouse the household for something that might have a simple, innocent explanation or she could follow the girl. Even in the heart of the Resistance village she wasn't safe. A look out the open door showed that Lizzie had already made it to the gate on the edge of the property. If Hermione didn't run after her in that second, she might lose all sight of the girl before she could tell her concerned parents where she went. Borrowing one of the cloaks hanging up on a hook next to the door, Hermione rushed outside in her slippers.
