Sorcerer's Stone
Chapter 7
The Sorting Hat
"Oh, you know Quirrell already, do you? No wonder he's looking so nervous, that's Professor Snape. He teaches Potions, but he doesn't want to -- everyone knows he's after Quirrell's job. Knows an awful lot about the Dark Arts, Snape.

Maybe he's left," said Harry, "because he missed out on the Defense Against Dark Arts job again!"

The Dementor
"Look at Snape!" Ron hissed in Harry’s ear.
Professor Snape, the Potions master, was staring along the staff table at Professor Lupin. It was common knowledge that Snape wanted the Defense Against the Dark Arts job, but even Harry, who hated Snape, was startled at the expression twisting his thin, sallow face. It was beyond anger: it was loathing. Harry knew that expression only too well; it was the look Snape wore every time he set eyes on Harry.

Chapter 8
Flight of the Fat Lady
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."

"He’s the best Defense Against the Dark Arts teacher we’ve ever had," said Dean Thomas boldly, and there was a murmur of agree-

ment from the rest of the class. Snape looked more menacing than ever.
"You are easily satisfied. Lupin is hardly overtaxing you -- I would expect first years to be able to deal with Red Caps and grindylows. Today we shall discuss --"

when they saw one. I shall make a point of informing Professor Dumbledore how very behind you all are…"

"Snape’s never been like this with any of our other Defense Against the Dark Arts teachers, even if he did want the job," Harry said to Hermione. "Why’s he got it in for Lupin? D’you think this is all because of the Boggart?"

"If Snape’s teaching Defense Against the Dark Arts again, I’m skiving off," said Ron as he headed toward Lupin’s classroom after lunch. "Check who’s in there, Hermione."

Chapter 14
The Unforgivable Curses
It was common knowledge that Snape really wanted the Dark Arts job, and he had now failed to get it for the fourth year running. Snape had disliked all of their previous Dark Arts teachers, and shown it--but he seemed strangely wary of displaying overt animosity to Mad-Eye Moody.

Chapter 17
Education Decree Number Twenty-Four
“You applied first for the Defense Against the Dark Arts post, I believe?” Professor Umbridge asked Snape.
“Yes,” said Snape quietly.
"But you were unsuccessful?"
Snape’s lip curled. “Obviously.”
pg 363
Professor Umbridge scribbled on her clipboard.
“And you have applied regularly for the Defense Against the Dark Arts post since you first joined the school, I believe?”
“Yes,” said Snape quietly, barely moving his lips. He looked very angry.
“Do you have any idea why Dumbledore has consistently refused to appoint you?” asked Umbridge.
“I suggest you ask him,” said Snape jerkily.
“Oh I shall,” said Professor Umbridge with a sweet smile.
“I suppose this is relevant?” Snape asked, his black eyes narrowed.
“Oh yes,” said Professor Umbridge. “Yes, the Ministry wants a thorough understanding of teacher’s – er – backgrounds…”

"Gesture!" she shrieked; in her fury she looked slightly mad. "While I endured the dementors, you remained at Hogwarts, comfortably playing Dumbledore's pet!"
"Not quite," said Snape calmly. "He wouldn't give me the Defense Against the Dark Arts job, you know. Seemed to think it might, ah, bring about a relapse...tempt me into my old ways."
"This was your sacrifice for the Dark Lord, not to teach your favorite subject?" she jeered. "Why did you stay there all that time, Snape? Still spying on Dumbledore for a master you believed dead?"
"Hardly," said Snape, "although the Dark Lord is pleased that I never deserted my post: I had sixteen years of information on Dumbledore to give him when he returned, a rather more useful welcome-back present than endless reminiscences of how unpleasant Azkaban is..."
pg 27
"I have played my part well," said Snape. "And you overlook Dumbledore's greatest weakness: He has to believe the best of people. I spun him a tale of deepest remorse when I joined his staff, fresh from my Death Eater days, and he embraced me with open arms -- though, as I say, never allowing me nearer the Dark Arts than he could help.

"Professor Snape, meanwhile," said Dumbledore, raising his voice so that it carried over all the muttering, "will be taking over the position of Defense Against the Dark Arts teacher."

"Professor Snape, meanwhile," said Dumbledore, raising his voice so that it carried over all the muttering, "will be taking over the position of Defense Against the Dark Arts teacher."
"No, said Harry, so loudly that many heads turned in his direction. He did not care; he was staring up at the staff table, incensed. How could Snape be given the Defense Against the Dark Arts job

after all this time? Hadn't it been widely known for years that Dumbledore did not trust him to do it?

Snape, who was sitting on Dumbledore's right, did not stand up at the mention of his name; he merely raised a hand in lazy acknowledgment of the applause from the Slytherin table, yet Harry was sure he could detect a look of triumph on the features he loathed so much.
"Well, there's one good thing," he said savagely. "Snape'll be gone by the end of the year."
"What do you mean?" asked Ron.
"That job's jinxed. No one's lasted more than a year...Quirrell actually died doing it...Personally, I'm going to keep my fingers crossed for another death..."

Chapter 9
The Half-Blood Prince
His black eyes roved over their upturned faces, lingering for a fraction of a second longer on Harry's than anyone else's.
You have had five teachers in this subject so far, I believe."
You believe...like you haven't watched them all come and go, Snape, hoping you'd be next, thought Harry scathingly.
"Naturally, these teachers will all have had their own methods and priorities. Given this confusion I am surprised so many of you scraped an O.W.L. in this subject. I shall be even more surprised if all of you manage to keep up with the N.E.W.T. work, which will be much more advanced."
Snape set off around the edge of the room, speaking now in a lower voice; the class craned their necks to keep him in view.
"The Dark Arts," said Snape, "are many, varied, every-changing, and eternal. Fighting them is like fighting a many-headed monster, which, each time a neck is severed, sprouts a head even fiercer and cleverer than before. You are fighting that which is unfixed, mutating, indestructible."
pg 177
Harry stared at Snape. It was surely one thing to respect the Dark Arts as a dangerous enemy, another to speak of them, as Snape was doing, with a loving caress in his voice?
"Your defenses," said Snape, a little louder, "must therefore be as flexible and inventive as the arts you seek to undo. These pictures" -- he indicated a few of them as he swept past -- "give a fair representation of what happens to those who suffer, for instance, the Cruciatus Curse" -- he waved a hand toward a witch who was clearly shrieking in agony -- "feel the Dementor's Kiss" -- a wizard lying huddled and blank-eyed, slumped against a wall -- "or provoke the aggression of the Inferius" -- a bloody mass upon the ground.

"You really shouldn't have said it," said Hermione, frowning at Ron. "What made you?"
"He tried to jinx me, in case you didn't notice!" fumed Harry. "I had enough of that during those Occlumency lessons! Why doesn't he use another guinea pig for a change? What's Dumbledore playing at, anyway, letting him teach Defense? Did you hear him talking about the Dark Arts? He loves them! All that unfixed, indestructible stuff -- "
"Well," said Hermione, "I thought he sounded a bit like you."
"Like me?"
pg 180
"Yes, when you were telling us what it's like to face Voldemort. You said it wasn't just memorizing a bunch of spells, you said it was just you and your brains and your guts -- well, wasn't that what Snape was saying? That it really comes down to being brave and quick-thinking?"

"Harry," Ernie said portentously, holding out his hand as Harry approached, "didn't get a chance to speak in Defense Against the Dark Arts this morning. Good lesson, I thought, but Shield
