She's jealous. She's ordinary, and you're special.

That's mean, Severus.

Gryffindor!

Hi, I'm James. Hi, I'm Lily.

C'mon, Moony. Padfoot. Snape!

Expelliarmus! Nice one, James.

C'mon James! Snivellus Snape Snape...

The one with the power to vanquish the Dark Lord approaches...

Hide her. Hide them all. I beg you. What will you give me in exchange, Severus?

Anything.

Good luck, Harry Potter.

You said you would keep her safe. Lily and James put their faith in the wrong

person, Severus. Rather like you. The boy survives.

He doesn't need protection, the Dark Lord is gone!

The Dark Lord will return, and when he does, the boy will be in terrible danger. If you

truly loved her...

No one can know.

There's not a witch or wizard who went bad who wasn't in Slytherin.

Ah.

That's Professor Snape.

What's he teach? Potions, but everyone knows it's the Dark

Arts he fancies.

Maybe some of you have come to Hogwarts in

possession of abilities so formidable that you feel confident enough to not pay attention.

Mr. Potter... ...our new celebrity.

I'm guessing Snape let the troll in as a diversion so he could get past that three-headed dog.

[gasps] It's Snape! He's jinxing the broom!

Fire!

You don't want me as your enemy, Quirrell. --W-What do you mean?

We'll have another little chat soon when you've had time to decide where your loyalties lie.

Snape doesn't want the Stone for himself, he wants the Stone for Voldemort.

N- No. It can't be...That day, during the Quidditch match. Snape tried to kill me.

No, dear boy. I tried to kill you! And trust me: if Snape's cloak hadn't caught fire and

broken my eye contact, I would have succeeded. Even with Snape muttering his little countercurse.

Snape was trying to save me? --Were you in Slytherin and your fate rested

with me, the both of you would be on the train home!

I never touched Mrs. Norris! --Innocent until proven guilty, Severus.

[Muttering in Parseltongue] --Neville, what frightens you most of all?

Professor Snape. Professor Snape. Yes, frightens all.

Riddikulus! [class laughs]

Your eyes. They're your mother, Lily's. Not only was she a singularly gifted witch, she

was also an uncommonly kind woman. She had a way of seeing the beauty in others, even,

and perhaps most especially, when that person could not see it in themselves.

How extraordinarily like your father you are, Potter, he too was exceedingly arrogant.

What's this? --Moony, Wormtail, Padfoot, and Prongs... offer

their compliments to Professor Snape... --Go on.

And request that he keep his abnormally large nose out of other people's business.

Brilliant, Snape. Once again you put your keen and penetrating mind to the task and

as usual come to the wrong conclusion. Now if you'll excuse us, Remus and I have

some unfinished business to attend to -- --Give me a reason.

Expelliarmus!

You look so like your father. Except your eyes. You have-- My mother's eyes.

Harry Potter... --Severus. Alastair. Keep an eye on Harry, will you?

[groan]

Severus, you know what it means as well as I!

I haven't stolen anything. --Don't lie to me.

You and your little friends are brewing Polyjuice Potion, and believe me, I'm going to find out why!

[sniffs] Polyjuice Potion.

Now we know who's been stealing from your stores, Severus.

How touchingly paternal, Black. Perhaps Potter will grow up to be a felon, just like his godfather.

Now you stay out of this, Snivellus.

Snape's part of the Order? --Git.

You applied first for the Defense Against the Dark Arts post, is that correct?

Yes. --But you were unsuccessful?

Obviously. [snickers]

[slap]

In the past, it was often the Dark Lord's

pleasure to invade the minds of his victims, creating visions designed to torture them

into madness. Only when he had them literally begging for

death would he finally...kill them. --You're just like your father. Lazy, arrogant--

Don't say a word against my father!

Weak -- --I'm not weak!

Then prove it. Control your emotions. Discipline your mind.

You and Black, you two-of-a-kind, sentimental children, forever whining about how bitterly

unfair your lives have been. Well, it may have escaped your notice, but

life isn't fair, your blessed father knew that, in fact, he frequently saw to it!

My father was a great man! --Your father was a swine!

Legilimens! --Protego!

Dad. --Impedimenta!

[chanting] Snivellus Snape! Who wants to see me take off Snivelly's trousers?

I didn't -- --Get. Out.

It will spread, Albus. We both know Lord Voldemort has ordered the

Malfoy boy to murder me. You must be the one to kill me, Severus.

You're very like your father. Except the eyes, of course, you have y--

My mother's eyes, yeah.

Cissy! You can't do this! He can't be trusted!

Over the years, I've played my part well. So well, I've deceived one of the greatest

wizards of all time. --When it matters most... he'll just slither

back into his hole.

Coward.

Watch over Draco Malfoy...

The post of Defense Against the Dark Arts

will be taken by Professor Snape. --[mutterings] Snape?

It was Malfoy. --Your evidence?

I just know. --You just...know.

Once again, you astonish me with your gifts, Potter, gifts mere mortals can only dream

of possessing. How grand it must be... to be the Chosen One.

[slams against the wall] I swore to protect you. I made the Unbreakable Vow.

I mean, to make an Unbreakable Vow -- --It comes down to whether or not you trust

Dumbledore's judgement. Dumbledore trusts Snape, therefore I do.

Dumbledore can make mistakes, he said so himself. --You're blinded by hatred.

I'm not! --Yes, you are!

Sectumsempra! --[groan]

Voldemort lives inside him.

So, when the time comes, the boy must die? --Don't tell me now that you've grown to care

for the boy.

Lily?

After all this time? --Always.

Have you ever considered that you ask too much, that you take too much for granted?

Has it ever crossed your brilliant mind that I don't want to do this anymore?

Severus.

Please.

Avada Kedavra!

Snape! He trusted you!

Fight back, you coward, fight back!

No!

Sectumsempra! --You dare you my own spells against me, Potter?

I'm the Half-Blood Prince.

S- Severus -- Severus please.

We're friends!

[gasps]

How dare you stand where he stood. Tell them how you looked him in the eye, a

man you trusted you, and killed him.

[cheers]

You've been a good and faithful servant, Severus.

Nagini, kill.

[bangs and thuds]

Take them. Take them.

Take them to the Pensieve. ...Look at me.

You have your mother's eyes.

Stay close to me.

Always.

Professor, my mother's Patronus was a doe.

It's the same as Professor Snape's. It's curious, don't you think?

Actually, if I think about it, it doesn't seem curious at all.

Albus Severus Potter. You were named after two headmasters of Hogwarts. One of them was

a Slytherin and he was the bravest man I've ever known.
