Harry, Ron, and Hermione sat down side by side at the end of the table.
“Crackers!” said Dumbledore enthusiastically, offering the end of a large silver noisemaker to Snape, who took it reluctantly and tugged. With a bang like a gunshot, the cracker flew apart to reveal a large, pointed witch’s hat topped with a stuffed vulture.
Harry, remembering the Boggart, caught Ron’s eye and they both grinned; Snape’s mouth thinned and he pushed the hat toward Dumbledore, who swapped it for his wizard’s hat at once.
“Dig in!” he advised the table, beaming around.
As Harry was helping himself to roast potatoes, the doors of the Great Hall opened again. It was Professor Trelawney, gliding toward them as though on wheels. She had put on a green sequined dress in honor of the occasion, making her look more than ever like a glittering, oversized dragonfly.
“Sibyll, this is a pleasant surprise!” said Dumbledore, standing up.
“I have been crystal gazing, Headmaster,” said Professor Trelawney in her mistiest, most faraway voice, “and to my astonishment, I saw myself abandoning my solitary luncheon and coming to join you. Who am I to refuse the promptings of fate? I at once hastened from my tower, and I do beg you to forgive my lateness…”
“Certainly, certainly,” said Dumbledore, his eyes twinkling. “Let me draw you up a chair—”
And he did indeed draw a chair in midair with his wand, which revolved for a few seconds before falling with a thud between Professors Snape and McGonagall. Professor Trelawney, however, did not sit down; her enormous eyes had been roving around the table, and she suddenly uttered a kind of soft scream.
“I dare not, Headmaster! If I join the table, we shall be thirteen! Nothing could be more unlucky! Never forget that when thirteen dine together, the first to rise will be the first to die!”
“We’ll risk it, Sibyll,” said Professor McGonagall inpatiendy. “Do sit down, the turkey’s getting stone cold.”
Professor Trelawney hesitated, then lowered herself into the empty chair, eyes shut and mouth clenched tight, as though expecting a thunderbolt to hit the table. Professor McGonagall poked a large spoon into the nearest tureen.
“Tripe, Sibyll?”
Professor Trelawney ignored her. Eyes open again, she looked around once more and said, “But where is dear Professor Lupin?”
“I’m afraid the poor fellow is ill again,” said Dumbledore, indicating that everybody should start serving themselves. “Most unfortunate that it should happen on Christmas Day.”
“But surely you already knew that, Sibyll?” said Professor McGonagall, her eyebrows raised.
