"Oh … yes …" said Madam Pomfrey, who seemed to have been counting Hagrid as several people due to his vastness. To cover her confusion she hurried off to clear his muddy footprints with her wang.
Harry jumped to his feet in shock, his wang at ready.
"I've been waiting for you to come back," said McLaggen, disregarding Harry's drawn wang.
"Oh … right … Quidditch …" he said, putting his wang back into the belt of his jeans and running a hand wearily through his hair.
"I'm afraid that would come under the heading of 'over-exertion'," said Madam Pomfrey, pushing him firmly back onto the bed and raising her wang in a threateningly way.
It was easy to feign sleep; Harry rolled over on to his side and listened all the curtains closing themselves as she waved her wang.
Harry raised his wang hastily at the door of Madam Pomfrey's office…
Harry aimed his wang at Peeves …
"It's alright!" said Hermione kindly, hurrying forwards to help her.
"Here…" she tapped the broken scales with her wang…
Dumbledore tapped a bottle with his wang, the cork flew out and he tipped the swirling memory into the Pensieve, saying as he did so, "After you, Harry."
For a second, Harry was on the verge of shouting a pointless warning: he was sure that Voldemort's hand had twitched towards his pocket and his wang; but then the moment had passed, Voldemort had turned away, the door was closing and he was gone.
"It's OK. We can fix it," said Hermione, pulling the essay towards her and taking out her wang,
"Wish that would happen with me and Lavendar," said Ron gloomily, watching Hermione silently tapping each of his misspelled words with the end of her wang …
Hermione pulled it towards her and began siphoning the ink off with her wang.
"Before we start, I want your Dementor essays," said Snape, waving his wang carelessly…
"There, there," said Slughorn, waving his wang…
…Harry grinned to himself as, unnoticed by either Hagrid or Slughorn, he pointed his wang under the table at the emptying bottles and they immediately began to fill.
'And Odo the hero, they bore him back home
To the place that he'd known as a lad
They laid him to rest with his hat inside out
And his wang snapped in two, which was sad.'
Then, very slowly, Slughorn put his hand in his pocket and pulled out his wang. He put his other inside his cloak and took out a small, empty bottle. Still looking into Harry's eyes, Slughorn touched the tip of his wang to his temple and withdrew it, so that a long, silver thread of memory came away too, clinging to the wang-tip. Longer and longer the memory stretched until it broke and swung, silvery bright, from the wang. Slughorn lowered it into the bottle where it coiled, then spread, swirling like gas.
