Jack certainly did not remember the red-haired girl from the train, but she clearly seemed to remember him.

"Oi," she shouted at him as he walked into Defense Against the Dark Arts. He strode over to her desk and lifted an eyebrow. "Can I help you?" he asked.

"You bumped into me on the Hogwarts Express and didn't apologize," the girl said, frowning at him.

"My deepest apologies, my lady," said Jack sarcastically, with a slight bow. He turned, but the girl hit him slightly over the head with a book. "Where you in a rush to? Class won't start for another few minutes, and you still haven't properly apologized."

He turned around, rubbing his head, and asked, "Didn't your mother teach you any manners?"

"Did yours?" she shot back.

"Don't have one," he said, staring her straight in the eye. She reminded him a bit of Cathy Ames, with her red hair and big attitude.

The red-haired girl in front of him was less of a pig than Ames, though. She had sharp blue eyes and a pale, freckle-less complexion. Her hair was curly instead of straight like Ames', and she spoke with a Scottish accent.

"Sorry, erm, I didn't…" said the girl, her tone more subdued. She was silent for a moment, then said, "Try not to knock me over in the future. Otherwise I'll do more than hit you with a book."

"Really?" Jack said, smirking at her. "What, would you hit me with one of those tiny fists of yours? Or maybe even try to hit me with a spell? I doubt you could even hit a turtle with a rock."

"Want to bet?" she said, bristling with anger. "I can hit a moving target with an arrow from ten meters away."

"An arrow?" he said, lifting an eyebrow. "What is this, the fifteenth century?"

"I can do it," she stated frankly, and with that determined and arrogant look in her eye, Jack just wanted to bring her down.

"Fine," he said. "If you can find a bow and arrow, show me how you can hit a moving target from ten meters away."

"If it's a bet, then there has to be a prize," she said, "something that one of us gets if the other loses the bet."

"Fine. If I win…" he said, thinking back to when they placed bets back at the orphanage. The prize that Jack always won was a rather simple one: extra pudding. But here he had unlimited pudding if he wanted it. He looked at the red-haired girl and thought of the thing she would hate the most. Well, she hates me… he thought, smiled, and made up his mind. "You have to give me a kiss."

She laughed. "Fine," she said. "Good thing I'm going to win. And when I do, you have to go to Argus Filch and tell him you want to help clean out the boys' bathroom on the third floor."

"That's so much worse!" he said, recoiling. It was only his first day and he had already heard stories about the boys' bathroom on the third floor.

"What, afraid you'll lose?" she said, smiling provokingly.

"Hardly," he said, leaning back against the desk behind him. "Best of luck to you, Red."

"Merida," she said. "And you?"

He smiled at her and said, "Jack Frost." He walked away and sat down just before the professor came in and began class.
