Go to the Quidditch pitch.

You head down to the Quidditch pitch, and change into you Quidditch robes. Kicking off from the snow-covered ground, you swoop in the air, cherishing the freedom to have, away from the prying eyes of fans and critics alike. The day is cold, but clear, and anyway, the exercise keeps you warm. When you finish, you've sweated through your clothes despite the chilly weather. You land to the sound of applause. You look towards the stands, your good mood souring as you see a figure sitting in the front row. Approaching him, you see that it's Cedric Diggory, your fellow Hogwarts Triwizard Chapion, Captain and Seeker of the Hufflepuff Quidditch team. Like you, he is also dressed in his Quidditch robes, and his broom is propped up next to him. You stand before Cedric, and glare at him.

"What are you doing here?" You ask hostilely.

Although Cedric himself hasn't treated you unfairly, you can't forget the misery some of his supporters have put you through.

"I came down to fly, too", he says, nodding at his broom, "but you beat me here. You fly well."

"Thanks", you say grudgingly, and turn to go.

"Wait!" Cedric yells, and you deign to pause. "I wanted to speak to you."
