"Buddy?"
Ron watched his brothers roughhousing as they disappeared from view. When he turned back, he found his best friend looking gloomy.
"What's wrong?" he asked, walking over with concern.

Ron took the letter, gave it a cursory glance, then promptly handed it back to Harry as though avoiding trouble.
"If you ask me, buddy, you're just getting too immersed in it." Ron reached out and patted Harry on the shoulder. "That was the love-hate feud between Harry Potter and Malfoy from a hundred years ago. What does it have to do with you?"

"Merlin's beard!" Ron clutched his head. "I can't guarantee what he'll say when he learns you're also called Harry Potter... Something like, 'Mr. Potter, do you think my sister would mourn for you?' Then he'll hit you with some Dark Arts... A Dark Wizard won't care which Harry you are. He only needs to know
