Mad Eye
Astoria Greengrass was in Diagon Alley with Scorpius, only a week before his first day at Hogwarts.
"Sorry your Father couldn't come," She said. "He would have been much better at helping you with getting your supplies than me."
Together, Scorpius and his mother went to choose a pet for Scorpius to take to Hogwarts. 10 minutes later, he arrived home.
"Look Dad!" he said excitedly. "I found him in the owl emporium!"
Draco flinched and turned chalk white as he saw the pure white ferret his son was holding.
"I named him mad-eye, because one of his eyes is bright green!"
Draco was always very careful never to be left alone in the same room with that ferret.
