We Are Only As Strong As We Are United

Hermione has to remind Harry and Ron that this sentiment extends to inter-House unity as well.

"Don't you remember what Dumbledore said at the end-of-term feast last year?"

Harry and Ron both looked at her blankly, and Hermione sighed again.

"About You-Know-Who.  He said, 'His gift for spreading discord and enmity is very great.  We can fight it only by showing an equally strong bond of friendship and trust--"

"How do you remember stuff like that?" asked Ron, looking at her in admiration.

"I listen, Ron," said Hermione with a touch of asperity.

"So do I, but I still couldn't tell you exactly what--"

"The point," Hermione pressed on loudly, "is that this sort of thing is exactly what Dumbledore was talking about.  You-Know-Who's only been back two months, and we've started fighting among ourselves.  And the Sorting Hat's Warning was the same--stand together, be united--"

"And Harry said it last night," retorted Ron, "if that means we're supposed to get matey with the Slytherins, fat chance."

"Well, I think it's a pity we're not trying for a bit of inter-House unity," said Hermione crossly. (OP12)
