“For an instant Harry imagined... Just for an instant, before his imagination blew a fuse and called an emergency shut down and told him never to imagine that again.”

“Sometimes Harry thought the deepest split in his personality wasn't anything to do with his dark side; rather it was the divide between the altruistic and forgiving Abstract Reasoning Harry, versus the frustrated and angry Harry In The Moment.”

“And then Harry Potter had launched in to a speech that was inspiring, yet vague. A speech to the effect that Fred and George and Lee had tremendous potential if they could just learn to be weirder. To make people's live surreal, instead of just surprising them with the equivalents of buckets of water propped above doors. (Fred and George had exchanged interested looks, they'd never thought of that one.) Harry Potter had invoked a picture of the prank they'd pulled on Neville - which, Harry had mentioned with some remorse, the Sorting Hat had chewed him out on - but which must have made Neville doubt his own sanity. For Neville it would have felt like being suddendly transported into an alternate universe. The same way everyone else had felt when they'd seen Snape apologize. That was the true power of pranking.”

“Without thinking about it at all, Harry stepped in front of Hermione.There was an intake of breath from behind him, and then a moment later Hermione brushed past and stepped in front of him. "Run, Harry!" she said. "Boys shouldn't have to be in danger.”

“Aside from helping people with their homework, or anything else they needed, she really didn't know how to meet people. She didn't feel like she was a shy person. She thought of herself as a take-charge sort of girl. And yet, somehow, if there wasn't some request along the lines of "I can't remember how to do long division" then it was just too awkward to go up to someone and say... what? She'd never been able to figure out what. And there didn't seem to be a standard information sheet, which was ridiculous. The whole business of meeting people had never seemed sensible to her. Why did she have to take all the responsibility herself when there were two people involved? Why didn't adults ever help? She wished some other girl would just walk up to her and say, "Hermione, the teacher told me to be friends with you".”

“‎If you regard evidence as a constraint and seek to free yourself, you sell yourself into the chains of your whims. For you cannot make a true map of a city by sitting in your bedroom with your eyes shut and drawing lines upon paper according to impulse.”

“World domination is such an ugly phrase. I prefer to call it world optimisation.”
