“Well, here goes," said Harry, and he raised the little bottle and took a carefully measured gulp.
"What does it feel like?" whispered Hermione.
Harry did not answer for a moment. Then, slowly but surely, an exhilarating sense of infinite opportunity stole through him; he felt as though he could have done anything, anything at all...and getting the memory from Slughorn seemed suddenly not only possible, but positively easy....
He got to his feet, smiling, brimming with confidence.
"Excellent," he said. "Really excellent. Right...I'm going down to Hagrid's."
"What?" said Ron and Hermione together, looking aghast. "No, Harry - you've got to go and see Slughorn, remember?" said Hermione.
"No," said Harry confidently. "I'm going to Hagrid's, I've got a good feeling about going to Hagrid's."
"You've got a good feeling about burying a giant spider?" asked Ron, looking stunned.
"Yeah," said Harry, pulling his Invisibility Cloak out of his bag. "I feel like it's the place to be tonight, you know what I mean?" "No," said Ron and Hermione together, both looking positively alarmed now.
"This is Felix Felicis, I suppose?" said Hermione anxiously, holding up the bottle to the light. "You haven't got another little bottle full - I don't know -"
"Essence of Insanity?" suggested Ron, as Harry swung his cloak over his shoulders.”

“Who're you going with, then?" said Ron.
"Angelina," said Fred promptly, without a trace of embarrassment.
"What?" said Ron, taken aback. "You've already asked her?"
"Good point," said Fred. He turned his head and called across the common room, "Oi! Angelina!"
Angelina, who had been chatting with Alicia Spinnet near the fire, looked over at him.
"What?" She called back.
"Want to come to the ball with me?"
Angelina gave Fred a sort of appraising look.
"All right, then," she said, and she turned back to Alicia and carried on chatting with a bit of a grin on her face.
"There you go," said Fred to Harry and Ron, "piece of cake.”

“Harry — I think I've just understood something! I've got to go to the library!”
And she sprinted away, up the stairs.
“What does she understand?” said Harry distractedly, still looking around, trying to tell where the voice had come from.
“Loads more than I do,” said Ron, shaking his head.
“But why’s she got to go to the library?”
“Because that’s what Hermione does,” said Ron, shrugging. “When in doubt, go to the library.”

“Ron, you're making it snow," said Hermione patiently, grabbing his wrist and redirecting his wand away from the ceiling from which, sure enough, large white flakes had started to fall. Lavender Brown, Harry noticed, glared at Hermione from a neighboring table through very red eyes, and Hermione immediately let go of Ron's arm.
"Oh yeah," said Ron, looking down at his shoulders in vague surprise." Sorry...looks like we've all got horrible dandruff now...."
He brushed some of the fake snow off Hermione's shoulder. Lavender burst into tears. Ron looked immensely guilty and turned his back on her.
"We split up," he told Harry out of the corner of his mouth. "Last night. When she saw me coming out of the dormitory with Hermione. Obviously she couldn't see you, so she thought it had just been the two of us."
"ah," said Harry. "Well - you don't mind it's over, do you?" "No," Ron admitted. "It was pretty bad while she was yelling, but at least I didn't have to finish it."
"Coward," said Hermione, though she looked amused. "Well, it was a bad night for romance all around. Ginny and Dean split up too, Harry."
Harry thought there was a rather knowing look in her eye as she told him that, but she could no possibly know that his insides were suddenly dancing the conga.”
