“Why are your hands purple?”
“That’s a very good question.”
“So what’s the answer?”
“Must be that new potion Draco and I have been working on. I didn’t know mandrake root turned your hands purple, though…probably because we never got to be in on that end of it at Hogwarts, just the repotting,” Harry mused. He turned as Draco walked into the room, his hands similarly stained. “Did you know mandrake root turned your hands purple, Dray?”
“No, and remind me to thank Longbottom for not cluing us in, either, the next time we see him,” Draco replied darkly. “He knew we were planning to put it in an experimental potion, the least he could have done is told us all the possible side effects before we left Hannah’s shop.”
“Believe me, you’ll have to beat me to him,” Harry muttered. “Must be his idea of a prank…he could learn a thing or two from George. Come to think of it, he probably already has,” he added, studying their stained hands.
