Percy Weasley, according to Ron, was an absolute and utter prat, who attached himself to the highest figure of authority he could and took their word as gospel. The twins had mentioned him having no sense of humor. Hermione, who had met him during an open study group, had described him as studious and hard working. Harry could only conclude from all these observations that he would not like Percy, and Percy would not like him.
This is why it was surprising when Harry heard the rustling of robes approaching his table, and looked up from his Potions homework to see a redhead in green trim sitting down and fixing him a hard stare.
"Granger." His voice was curiously sharp for a greeting.
"Er, Percy, right?"
"Indeed. We need to speak about my brother," he said. "He has simply become insufferable lately. Rude would not bother me, Ronald is just that way. But as of late his temper has become far too short and far too snappish, in particular towards myself and my cohort."
Harry looked him over. He was similar to Ron, physically, tall and gangly, but he spoke incredibly differently; where Ron went out of his way to use as few words as possible, Percy abuse his vocabulary with a bullwhip.
"Yeah, well, I have no idea why, if that's what you're asking." Harry turned his attention back to his parchment. He did, of course, have an idea of what was making Ron act so weird, but he wasn't going to tell this pretentious git that.
"I don't wish to know, nor do I care. I only want it to end." Percy fixed him a stare. "He will not listen to me and hasn't since I became a Slytherin." And that made sense. Whenever Ron talked about Percy it was always something about being the first Weasley in Slytherin ever and how it was so very scandalous. Regardless, Harry snorted.
"If he won't listen to his own brother, why would he listen to me? Why don't you go to Fred and George or something, I'm sure they can do better than I can."
"Because, Granger, I saw you two before he began acting so oddly. He values your opinion, and your friendship, though why I haven't the faintest idea." Harry shot a look at him. "Listen, I'm not asking because I dislike Ronald's treatment of me, that is something I've grown accustomed to. I ask because I'm concerned for him. This is uncouth even for him, and I fear there may be some greater issue at cause." Harry blinked twice. All he had really understood was that Percy was legitimately worried about Ron, and that shot his stock up in Harry's book. He sighed.
"Fine. I'll talk to him after Quidditch tomorrow."
"Thank you Granger."
