A person doesn't just wake up one day and stop loving somebody.

I only have Eyes for You

Buffy: I'm not seeing anybody. Ever again, actually.

Buffy: Yeah. I'm gonna stop by the library and see if Giles wants me to patrol, and then sack it.
Willow: You've been doing that a lot. Patrolling and sacking. In fact, you've kind of been All-Work-And-No-Play Buffy.
Buffy: I play. I have big fun. I came here tonight, didn't I?
Willow: You came, you saw, you rejected.

Buffy: Impulsive? Do you remember my ex-boyfriend, the vampire? I slept with him, he lost his soul, now my boyfriend's gone forever, and the demon that wears his face is killing my friends. The next impulsive decision I make will involve my choice of dentures.

Snyder: What would Sunnydale High do without you around to incite mayhem, chaos and disorder?
Buffy: I don't incite! I stopped that boy from killing his girlfriend, ask him. Ask the janitor.
Snyder: People can be coerced, Summers. I'm no stranger to conspiracy. I saw 'JFK.' I'm a truth seeker. I've got a missing gun and two confused kids on my hands. Pieces of the puzzle. And I'm gonna look at all the pieces carefully and rationally, and I'm gonna keep looking until I know exactly how this is all your fault.

Willow teaching computer class: So, for next time read the chapters on information grouping and binary coding. I bet you'll think coding is pretty cool. I mean, if you find two-digit, multi-stacked conversions and primary number clusters a big hoot. (The class leaves; Giles enters) Giles! I made them laugh, did you hear? I did the joke thing!

Buffy: I'm telling you, something weird is going on.
Xander: 'Something weird is going on.' Isn't that our school motto?

Xander: You're just a big bucket of funny, Will.

Giles: Ooh! Sounds like paranormal phenomena.
Willow: A ghost? Cool!
Xander: Oh, no, no. No. No cool. This was no wimpy chain rattler. This was 'I'm dead as hell, and I'm not gonna take it anymore.'
Giles: Well, despite the Xander-speak, that's a fairly accurate definition of a poltergeist.
Xander: I defined something? Accurately? Guess I'm done with the book learning.

Giles: Unfortunately, he doesn't know exactly what he wants. That's the trouble. See, many times the spirit is plagued by all manner of worldly troubles. Being dead, it has no way to make its peace. So it lashes out, growing ever more confused, ever more angry.
Buffy: So it's a normal teenager, only dead.

Buffy: Fabulous. Now we're Dr. Laura for the deceased.

Giles: Yes, well, I appreciate your thoughts on the matter, I, in fact, well, I encourage you to always challenge me when you feel it's appropriate. You should never be cowed by authority. Except, of course, in this instance, when I am clearly right and you are clearly wrong.

Xander on Giles: He's usually Investigate-Things-From-Every-Boring-Angle Guy. Now he's I-Cling-Onto-My-One-Lame-Idea Guy.

Xander: Yikes. The quality of mercy is not Buffy.

Buffy: Who cares what he wants? We need to shut him down before some other innocent guy goes and kills some poor nice girl and then blows his brains out all over the music room wall.
Xander: Okay! Who's hungry?

Snyder: We're on a Hellmouth. Sooner or later, people are gonna figure that out.
Police Officer: The city council was told that you could handle this job. If you feel that you can't, perhaps you'd like to take that up with the Mayor.
Snyder: I'll handle it. I will.

Willow: I've done some homework and found the only solution is the final solution.
Xander: Nuke the school? I like that.
Willow: Not quite. Exorcism.
Cordelia: Are you crazy? I saw that movie! Even the priest died!

Willow: Oh! I almost forgot. I made us all scapulas.
Xander: Okay, so we can flip the ghost over when it turns a nice golden brown?
Willow: Scapula, not spatula. You wear it around your neck for protection.
Cordelia: You expect me to wear this? It smells like grandpa breath.

Xander: Oh, yeah, baby, it's snake-alicious in here.

James: GET OUT!!!

Willow: Giles, Jenny could never be this mean.
Giles: I know. It's not her, is it?

Looking at the school, which is covered in wasps:
Xander: I'd say school's out for good.

Cordelia: Hey. If Sunnydale High School shuts down forever, do we automatically graduate?
Xander: But why? What does he want? Actually, that's an interesting point.

Buffy: He wants forgiveness.
Giles: Yes. I imagine he does. But when James possesses people, they act out exactly what happened that night. So he's experiencing a form of purgatory instead. I mean, he's doomed to kill his Ms. Newman over and over and over again, and... forgiveness is impossible.
Buffy: Good. He doesn't deserve it.
Giles: To forgive is an act of compassion, Buffy. It's not done because people deserve it. It's done because they need it.
Buffy: No. James destroyed the one person he loved the most in a moment of blind passion. And that's not something you forgive. No matter why he did what he did. And no matter if he knows now that it was wrong and selfish and stupid, it is just something he's gonna have to live with.
Xander: He can't live with it, Buff. He's dead.
(Buffy walks out of the room)
Cordelia: Okay. Overidentify much?

Angel: Fun fact about wasps. They have no taste for the undead.

Buffy: You can't make me disappear just because you say it's over.
Angel: Actually... I can. In fact... I just want you to be able to have some kind of normal life. We can never have that, don't you see?
Buffy: I don't give a damn about a normal life! I'm going crazy not seeing you. I think about you every minute.
(Cut to 1955)
Ms. Newman: I know. But it's over. It has to be!
(Back in the present)
Buffy: Come back here! We're not finished! You don't care anymore, is that it??
Angel: It doesn't matter, it doesn't matter what I feel.
Buffy: Then tell me you don't love me!
(Cut to 1955.)
James: Say it!
Ms. Newman: Is that what you need to hear? Will that help? I don't.
(Back to the present.)
Angel: I don't. Now let me go.
Buffy: No. A person doesn't just wake up and stop loving somebody! Love is forever.

Buffy: Grace!
Angel: Don't do this.
Buffy: But--but I killed you.
Angel: It was an accident. It wasn't your fault.
Buffy: Oh, it is my fault. How could I...
Angel: Shhh. I'm the one who should be sorry, James. You thought I stopped loving you. But I never did. I loved you with my last breath.

Willow: Everything seems normal. Not a snake, not a wasp.
Cordelia: Yep. School can open again tomorrow.
Xander: Explain to me again how that's a good thing.
Cordelia: I'm drawing a blank.
