Jack stared forward, looking at a speck on the wall. It looked like a grease stain, and she couldn't, for the life of her, figure out why it was there. It looked older, so it had probably been there before Professor Lupin took over the office, which only deepened the mystery. Weird.
She didn't care about the detention, nor did she care about the points. Quidditch was scheduled around her extra-curricular disciplinary actions, and it gave her more of a reason to win by a large margin. The House Cup didn't matter, anyway. For someone who had spent her week beating up and taunting Slytherins, she didn't care for this division of people. It was school - division was going to happen without the help or affirmation of the institution. At the end of the day, she didn't care. Matthew could do or say or think whatever he wanted.
It was just interesting how it never stopped.
She was feeling herself fall away from herself, the way she did at family dinners, when her mother threw barbs, pointed insults about the influence she might have over her little cousin. When Charlie wasn't home, Jack could lash back. But with the eyes of her surrogate sister on her, Jack had to find that place within her where nothing reached inside her.
And then Matt's words reached her, from deep within that sunken place of hers. And she fell back on the instinct she felt most sincerely - full blown teenage defiance.
"No he didn't," she said, her eyes sliding to the professor. "I instigated. I spent all of detention throwing things at his head. I knew it would wind him up, an I wanted to see if it took less time than it did at Duelling Club."
Lupin nodded. "Okay, so why do you think you did that?"
"I wanted to see how much I could hide in his hair. I figured I could get a History of Magic essay's worth."
She spoke matter of factly, without humor, and it was clear - Professor Lupin was feeling out of his depth.
