Who: James and Lily, possibly Peter
Why: People are getting sick again.
Lily rubbed at her eyes as she stood before the portrait, having to think for a moment to remember the password. She was exhausted, but there was just so much to do. Half of the school was sick, a significant percentage of them Gryffindors, and she had to play prefect for them all. And then there were her friends who were sick and now Peter needed rescuing. Not to mention the fact that she hadn't eaten anything in hours. But she didn't have the luxury of thinking of herself right now.
"I don't have all day" the Fat Lady commented irritatedly, shaking her head. Lily thought that was a bizarre thing to say, since she did, in fact, have all day. It wasn't as though she was going to go anywhere.
"Sorry, I.." she broke off as she saw James walking towards her. She was slightly embarrassed that she couldn't remember the password, but she knew he would know it and he wouldn't think less of her for forgetting.
