Hermione would've said something, already opening her mouth but the sudden noise nearby interrupted them. It was too loud for a library. She lifted an eyebrow and looked at Draco who shrugged and stood up, ready to scare someone off. He too recognized the heard voices, making him roll his shoulders back in annoyance. Hermione came closer, hiding behind the bookshelf, enough to see the intruders. She felt Draco come up behind her, interested as well at hearing and seeing more.
