Headcanons!

Dean traced the outline of a chair. He darkened it shading the centre and drawing the surroundings. Drawing made him feel free, gave his churning mind something to concentrate on. He poured his heart and soul into his art.
"Time's up!" The teacher's shrill voice startled him. He put down his pencil and looked around. A girl with fiery hair was standing next to him, at an easel. The class began to wander around, looking at others' work. He stopped at his neighbour's easel, looking around the room for the red-headed girl he had seen earlier. She was next to him, admiring his own artwork. She saw him looking, and started a conversation.
"Hi," she began, facing him, "I like your drawing. What's your name?"
"Dean Thomas," he answered, "What's yours?"
"Rachel Elizabeth Dare."

There was a big party being hosted at the Weasley's. Everyone was coming, including the Weasley's distant squib relative, who was an accountant. Her whole family came, including her daughter's friends. Dean did not expect Rachel to be there. Nor did he expect his sister's best friend, Shel, who had moved to America years ago, to be good friends with Rachel. But there it was. The Dares and the Weasleys were related.
