Malfoy didn't reappear in classes until late on Thursday morning, when the Slytherins and Gryffindors were halfway through double Potions. He swaggered into the dungeon, his right arm covered in bandages and bound up in a sling, acting, in Harry's opinion, as though he were the heroic survivor of some dreadful battle.

"How is it, Draco?" simpered Pansy Parkinson. "Does it hurt much?"

"Yeah," said Malfoy, putting on a brave sort of grimace. But Harry saw him wink at Crabbe and Goyle when Pansy had looked away.

Amelia scoffed. "That bastard. I nearly got my guts ripped out at eleven and was back to school the next day. Fucking bastard! That's it I'm going to make sure he hurts for real," Amelia took a step to get out of her seat but Hermoine who was behind her caught her shoulder and shoved her back down. 

"Settle down, settle down," said Professor Snape idly.

Harry and Ron scowled at each other; Snape wouldn't have said "settle down" if they'd walked in late, he'd have given them detention. But Malfoy had always been able to get away with anything in Snape's classes; Snape was head of Slytherin House, and generality favored his own students above all others.

They were making a new potion today, a Shrinking Solution. Malfoy set up his cauldron right next to Harry and Ron, so that they were preparing their ingredients on the same table.

"Sir," Malfoy called, "sir, I'll need help cutting up these daisy roots, because of my arm --"

"I had elbow surgery on my right arm when I was eight. And couldn't use my fucking left hand. He is fucking left-handed. Bastard can chop his own roots the faker." Amelia muttered to herself as she chopped her roots. 

"Weasley, cut up Malfoy's roots for him," said Snape without looking up. Ron went brick red.

"There's nothing wrong with your arm," he hissed at Malfoy.

Malfoy smirked across the table.

"Weasley, you heard Professor Snape; cut up these roots."

Ron seized his knife, pulled Malfoy's roots toward him, and began to chop them roughly, so that they were all different sizes.

"Professor," drawled Malfoy, "Weasley's mutilating my roots, sir."
