Hermione Granger was sitting in the prefects' car of the train back to Hogwarts thinking about how she spent this summer. Her parents were losing some of her muggle ways and sent her to spend her summer with her American cousins. She spent her three month vacation in the sunny state of Florida. She was now tanner and the owner of a wardrobe that was so skimpy that she would never let any one of her friends see.
That summer she learned how to play several "muggle" games. She wanted to play them with all her wizard friends, with a few magical twists that she was working out. Hermione was a list maker; she pulled out a notebook and looked at the list and sub-lists of what games she learned and how to play them.
Draco Malfoy waltzed into the train car and saw Hermione writing into a journal. He snatched the journal and started reading aloud, or at least tried to. "Granger, what is this?" Draco sneered.
"Well Malfoy, why should I tell you?" Hermione said, crossing her arms, getting a defiant look on her face.
"Fine then, I'll just figure it out for myself." He said. Draco sat down and crossed his ankles, opening the book to the page that she was at. He started to stare at the page and just stared until Hermione snatched the book back.
"I wrote it backwards." She said. "It's just a list of muggle games that I want to play with my friends."
"I want you to teach me them." He said a minute later after deeply pondering it first. He had spent his summer in the American muggle world as well. He spent it in New York City and was very impressed with the muggle culture. "I want this to be a secret. If certain people found out that I wanted to learn about muggles then they would kill me. Got that." Hermione nodded.
"I will teach you, but If you want to learn you have to learn with my friends got it?" She said, very controlling.
"got it." He said "So we have a deal?" He stood up and stuck out his hand.
"Deal." She said mimicking his action. They shook hands. She was slightly surprised at how nicely he held her hand. "Good. The first game starts soon. If you want any Slytherin friends you better convince them now."
