Cassie hesitated on the stairs, not wanting to be near a vampire. But then again, Andriel had said she wouldn't bite her. Cassie slowly went down the stairs and carefully walked past Andriel, who did and said nothing as she walked by. Cassie went out in the corridor and heard someone talking off in the distance. Cassie silently moved down the corridor. It was Marcella and Kristi. There was no point turning back now, so Cassie continued to follow them. By the sound of it, they were on their way to see Snape.
