"Percy? Who's that?" stuttered Harry, looking at the professor with white skin talking to another professor with long, dark, greasy hair.

Percy looked at the table. "Who, Harry? The one with dark hair? That's Professor Snape. He's the Potions teacher, though everyone know he'd prefer teach Defence Against the Dark Arts."

"Not him! I mean the professor with bone white skin!"

"Bone white skin?" repeated Percy, frowning.

"Talking to Professor Snape! The man with the turban!"

"Oh. That's Professor Quirrell, the current Defence teacher. I really don't get what you mean by 'bone white skin', though."

Harry gaped at the fifth-year prefect. "How can you not see it? His skin is as white as marble!"

Percy looked at the younger student, baffled. "What are you talking about, Harry? His skin look perfectly normal!"

Harry blinked. Was he becoming crazy? Harry continued to stare at Quirrell while he ate. Then, unexpectedly, the professor turned.

"Percy, his eyes are red!" he gasped quietly.

Percy sighed frustratingly. "No, Harry. His eyes are brown." said the prefect, barely glancing at the professor.

Harry stared back at his meal, not hungry anymore. What was going on? Why was he seeing Professor Quirrell like he had bone white skin and red eyes? Percy clearly didn't see it. So why did he?
