"Miss Brocklehurst," he said, taking Gabe's hand and approaching his former student. "A pleasure to see you. You can call me Remus, you know. I haven't been a professor for...what, ten years now?"
"Gabe," he said to his son. "This is Mandy Brocklehurst. She was a student of mine at Hogwarts. Can you say hello?"
"Hullo," Gabriel replied distractedly as a street vendor passed with a cart of sweets.
"This is Gabriel," Remus said. "You remember Professor Tonks? This is our son."
