Harry looked at him. Lupin’s eyes were twinkling.
“How did you know about that?” Harry asked.
“Professor McGonagall told me,” said Lupin, passing Harry a chipped mug of tea. “You’re not worried, are you?”
“No,” said Harry.
He thought for a moment of telling Lupin about the dog he’d seen in Magnolia Crescent but decided not to. He didn’t want Lupin to think he was a coward, especially since Lupin already seemed to think he couldn’t cope with a boggart.
Something of Harry’s thoughts seemed to have shown on his face, because Lupin said, “Anything worrying you, Harry?”
“No,” Harry lied. He drank a bit of tea and watched the grindylow brandishing a fist at him. “Yes,” he said suddenly, putting his tea down on Lupin’s desk. “You know that day we fought the boggart?”
“Yes,” said Lupin slowly.
“Why didn’t you let me fight it?” said Harry abruptly.
Lupin raised his eyebrows.
“I would have thought that was obvious, Harry,” he said, sounding surprised.
Harry, who had expected Lupin to deny that he’d done any such thing, was taken aback.
“Why?” he said again.
“Well,” said Lupin, frowning slightly, “I assumed that if the boggart faced you, it would assume the shape of Lord Voldemort.”
Harry stared. Not only was this the last answer he’d expected, but Lupin had said Voldemort’s name. The only person Harry had ever heard say the name aloud (apart from himself) was Professor Dumbledore.
“Clearly, I was wrong,” said Lupin, still frowning at Harry. “But I didn’t think it a good idea for Lord Voldemort to materialize in the staffroom. I imagined that people would panic.”
“But then,” said Harry honestly. “I — I remembered those dementors.”
“I see,” said Lupin thoughtfully. “Well, well . . . I’m impressed.” He smiled slightly at the look of surprise on Harry’s face. “That suggests that what you fear most of all is — fear. Very wise, Harry.”
Harry didn’t know what to say to that, so he drank some more tea.
“So you’ve been thinking that I didn’t believe you capable of fighting the boggart?” said Lupin shrewdly.
“Well . . . yeah,” said Harry. He was suddenly feeling a lot happier. “Professor Lupin, you know the dementors —”
He was interrupted by a knock on the door.
“Come in,” called Lupin.
The door opened, and in came Snape. He was carrying a goblet, which was smoking faintly, and stopped at the sight of Harry, his black eyes narrowing.
“Ah, Severus,” said Lupin, smiling. “Thanks very much. Could you leave it here on the desk for me?”
Snape set down the smoking goblet, his eyes wandering between Harry and Lupin.
“I was just showing Harry my grindylow,” said Lupin pleasantly, pointing at the tank.
“Fascinating,” said Snape, without looking at it. “You should drink that directly, Lupin.”
“Yes, yes, I will,” said Lupin.
“I made an entire cauldronful,” Snape continued. “If you need more.”
“I should probably take some again tomorrow. Thanks very much, Severus.”
“Not at all,” said Snape, but there was a look in his eye Harry didn’t like. He backed out of the room, unsmiling and watchful.
Harry looked curiously at the goblet. Lupin smiled.
“Professor Snape has very kindly concocted a potion for me,” he said. “I have never been much of a potion-brewer and this one is particularly complex.” He picked up the goblet and sniffed it. “Pity sugar makes it useless,” he added, taking a sip and shuddering.
“Why — ?” Harry began. Lupin looked at him and answered the unfinished question.
“I’ve been feeling a bit off-color,” he said. “This potion is the only thing that helps. I am very lucky to be working alongside Professor Snape; there aren’t many wizards who are up to making it.”
Professor Lupin took another sip and Harry had a crazy urge to knock the goblet out of his hands.
“Professor Snape’s very interested in the Dark Arts,” he blurted out.
“Really?” said Lupin, looking only mildly interested as he took another gulp of potion.
“Some people reckon —” Harry hesitated, then plunged recklessly on, “some people reckon he’d do anything to get the Defense Against the Dark Arts job.”
Lupin drained the goblet and pulled a face.
“Disgusting,” he said. “Well, Harry, I’d better get back to work. I’ll see you at the feast later.”
“Right,” said Harry, putting down his empty teacup.
The empty goblet was still smoking.
“There you go,” said Ron. “We got as much as we could carry.”
A shower of brilliantly colored sweets fell into Harry’s lap. It was dusk, and Ron and Hermione had just turned up in the common room, pink-faced from the cold wind and looking as though they’d had the time of their lives.
“Thanks,” said Harry, picking up a packet of tiny black Pepper Imps. “What’s Hogsmeade like? Where did you go?”
By the sound of it — everywhere. Dervish and Banges, the wizarding equipment shop, Zonko’s Joke Shop, into the Three Broomsticks for foaming mugs of hot butterbeer, and many places besides.
“The post office, Harry! About two hundred owls, all sitting on shelves, all color-coded depending on how fast you want your letter to get there!”
“Honeydukes has got a new kind of fudge; they were giving out free samples, there’s a bit, look —”
“We think we saw an ogre, honestly, they get all sorts at the Three Broomsticks —”
“Wish we could have brought you some butterbeer, really warms you up —”
“What did you do?” said Hermione, looking anxious. “Did you get any work done?”
“No,” said Harry. “Lupin made me a cup of tea in his office. And then Snape came in. . . .”
He told them all about the goblet. Ron’s mouth fell open.
“Lupin drank it?” he gasped. “Is he mad?”
