“Half an hour later, each of them had been given a complicated circular chart, and was attempting to fill in the position of the planets at their moment of birth. It was dull work, requiring much consultation of timetables and calculation of angles.“I’ve got two Neptunes here,” said Harry after a while, frowning down at his piece of parchment, “that can’t be right, can it?”“Aaaaah,” said Ron, imitating Professor Trelawney’s mystical whisper, “when two Neptunes appear in the sky, it is a sure sign that a midget in glasses is being born, Harry . . .”

“Aaah ... said Ron, imitating Professor Trelawney’s mystical whisper, when two Neptunes appear in the sky it is a sure sign that a midget in glasses is being born, Harry...”

“Fifty?” Harry gasped.“Fifty points each,” said Professor McGonagall, breathing heavily.“Professor — please —”“You can’t —”“Don’t tell me what I can and can’t do, Potter. I’ve never been more ashamed of Gryffindor students.”

“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.”

“An Unbreakable Vow?" said Ron, looking stunned. "Nah, he can’t have.... Are you sure?""Yes I’m sure," said Harry. "Why, what does it mean?""Well, you can’t break an Unbreakable Vow...""I’d worked that much out for myself, funnily enough.”

“Hang on . . .” Harry muttered to Ron. “There’s an empty chair at the staff table. . . . Where’s Snape?”"Maybe he's ill!" said Ron hopefully. “Maybe he’s left,” said Harry, “because he missed out on the Defense Against the Dark Arts job again!”“Or he might have been sacked!” said Ron enthusiastically. “I mean, everyone hates him —”“Or maybe,” said a very cold voice right behind them, “he’s waiting to hear why you two didn’t arrive on the school train.”Harry spun around. There, his black robes rippling in a cold breeze, stood Severus Snape.”

“Oh, don’t lie, Harry,” she said impatiently. “Ron and Ginny say you’ve been hiding from everyone since you got back from St. Mungo’s.”“They do, do they?” said Harry, glaring at Ron and Ginny. Ron looked down at his feet but Ginny seemed quite unabashed.“Well, you have!” she said. “And you won’t look at any of us!”“It’s you lot who won’t look at me!” said Harry angrily.“Maybe you’re taking it in turns to look and keep missing each other,” suggested Hermione, the corners of her mouth twitching.”
