"Er… Harry, Hermione, are you dead?" Ron asked cautiously, seeing his two best friends sprawled on a sofa looking decidedly ill.
"No, why?" Harry asked.
"Your faces are both grey, like you're dead or something," Ron said.
"I can't be grey," Harry said.
"You are. So's Hermione."
"But I'm depressed, and she's hung over," Harry objected. "That can't possibly make us grey." Ron rolled his eyes and fished out a little pink mirror from the pocket of his robes.
Harry looked in the mirror, gasped, and looked at Hermione.
"Oh no!" he cried. "We're both suffering from the after-effects of a traumatic sight! We're supposed to look blue!"
