Shock rippled around the room when Fleur pulled off an invisibility cloak, leaning against the arm of Hermione's chair. It wasn't as amazing as Potter's cloak but it was a family heirloom that had been passed down the Delacour Family for centuries. Traditionally, Fleur wouldn't take ownership of it until she became leader of the Clan but there was nothing wrong with claiming inheritance early. Of course, they had to time Fleur's arrival into the school at the right time otherwise Potter would have looked at his fancy map and called them out on it. Not tonight though, Hermione had swiped it earlier - whispering to Potter that she would check it at night to see if Draco had left the Common Room.
