Allison woke up when a house elf had told her of Snape's impending visit, careful not to jostle herself too much as she sat up in bed. Healer Nott had assured her that she wouldn't be able to re-open the cuts by moving but it still made her nervous to know that at any time, she could be susceptible to either excruciating pain or seeing a lot of blood very quickly.
Fun it most definitely wasn't.
Hearing the knock on the door and granting access she looked at the man assessingly when he entered. She'd been told a little about him and had met him already once but she didn't know much. Only that he was back from the dead and could hopefully help them. One of the mediwitches had said that he could be their only chance and that what Snape had forgotten about Potions was more than most people could ever hope to know.
