Chapter 39:
Making sure to jump, Harry turned to look at the scheming old man. "I'm sorry sir, I didn't see you there," Harry stuttered out.
"It's okay, my dear boy. Many a man are drawn to the mirror," Dumbledore said sagely.
"I don't know, sir," Harry said, in reply to his earlier question.
"Really, you have no idea?" Dumbledore asked.
"Well, I guess it shows what we want?" Harry replied, making sure to sound uncertain.
"Take a closer look, Harry," Dumbledore prompted.
Walking to the mirror, Harry pretended to observe it before 'finding' the inscription. "Erised stra ehru oyt ube cafru oyt on wohsi," Harry mumbled before pretending to figure it out. "I show not your face, but your heart's desire!" he exclaimed happily.
"Very good, Harry," Dumbledore said, his tone just shying away from patronising but still setting Harry's teeth on edge.
"So, I see my parents because they're what I want most?" Harry asked.
