Baby, it's cold outside
Our story begins in an abandoned corridor of Hogwarts where Fawkes has hidden the portrait of Ariana.
Ariana sighed. "I miss being able to feel like you do, I love winter."
Fawkes smiled. "Baby, it's cold outside."
Ariana said, "I love the cold."
Fawkes grinned. "I can bring a little bit of the Christmas spirit to your new home."
Without waiting for a reply, he took off. He returned several minutes later with a miniature Christmas tree and Christmas decorations.
Ariana told him, "Put the tree close to me."
Fawkes did so and arranged the decorations around her frame and the rest of the room.
He asked, "Is that better?"
Ariana frowned. "There's no snow."
Fawkes smirked. "Just wait a minute."
He flew away and returned with a box.
He said, "Close your eyes."
Ariana did so and Fawkes dropped the contents of the box from the roof.
He shouted, "Open your eyes!"
Ariana opened her eyes and beamed, "It's really snowing."
Fawkes smiled. "Well, as close to snow indoors as I could get."
