Noctis & Belle
Belle was walking the halls on her rounds when the voice boomed through the castle, and she looked around at the bare walls, trying to remember what common room was nearest to her. This wasn't something that had happened before and she was unnerved by the seriousness in Emrys' voice. It was uncommon, the Headmaster was typically a laid back old man.
When the wall opened to a teacher Belle startled slightly but followed the other students in. It was obviously Slytherin, and she looked around slightly warily before her eyes settled on Noctis, making an attempt to leave the room. She frowned at that, but ignored the fact that he wanted to leave and moved quickly to where he was. She didn't speak immediately, just looked up at him almost pleadingly- visually begging him to take her with him, or at least to not leave her alone here.
