Work Text:
Alice walked into the Common Room to see Mary upside down on the sofa, while Lily was finishing some writing, also upside down.
"I want to know what you are doing?" Alice asked, before shaking her head and saying. "You know what, I really don't want to know. Enjoy what you're doing."
Lily looked up to say. "I wrote you the Potions essay while you were out with Frank."
"Oh thanks!"
"Do not thank me." Lily said quietly as Alice started up the stairs. "You can always thank me tomorrow."
Alice stopped.
"Or the day after. Or the day after that."
"Did you follow me?" Alice felt betrayed, leaving the two girls to laugh at each other.
She would take revenge.
