She might have known it was almost too good to last.
It started when Draco Malfoy took a particular interest in his fellow Slytherin's relationship to a certain Gryffindor. His blond helmet of hair gleamed in the sunlight streaming through the Great Hall's high windows as he stared blatantly at the two of them sitting at the far end of the Gryffindor table. He'd noticed that Graves had been taking meals away from his house table more and more often. When he noticed the older boy was eating with Guenivere LeFey he was enraged.
She was friends with Harry Potter.
He started to form a plan in his oily little brain. He was going to rip those two apart if it was the last thing he did. No self-respecting Slytherin would ever eat at the Gryffindor table, let alone date one of them. His mind cranked out idea after idea, but nothing seemed quite right.
Maybe if Graves found Gwen kissing someone else. Oh that's mature, Malfoy thought. No, it needed to be something more terrifying. He could easily knock her against a wall a few times with the help of Crabbe and Goyle. but physical violence seemed just too easy. Perhaps this was one of those instances where all those awful curses and hexes he'd been working on would come in handy.
He smiled as the gears began to turn in his head.
