Cordelia: You want I should distract him? Make with the nice-nice while you slip by?
Angel: Don't be stupid. I'm that guy and the most beautiful woman I've ever seen is making eyes at me? It's either a bachelor party or a scam.
Cordelia: What did you just call me?
Angel: I'm sorry. You're not stupid.
Cordelia: No, after that.
[Sunlight in Pylea doesn't harm vampires.]
Angel: Can everybody just notice how much fire I'm not on?
Angel: I saw their production of "Giselle" in 1890. I wept like a baby, and I was evil!
Cordelia: I finally get invited to a nice place with no mirrors and lots of curtains. Hey, you're a vampire!
Russell Winters: What? No, I'm not.
Cordelia: Are too!
Russell Winters: I don't know what you're talking about.
Cordelia: I'm from Sunnydale. We had our own Hellmouth. I think I know a vampire when... I'm... Alone with him... In his fortress-like home.
In The Dark - S1-E3
[Watching from on top of a building as Angel talks to a woman he just saved, Spike guesses what is being said.]
Spike: [as Rachel.] How can I thank you, you mysterious black-clad hunk of a night thing?
[as Angel.] No need, little lady, your tears of gratitude are enough for me. You see, I was once a badass vampire, but love and a pesky curse defanged me. Now I'm just a big, fluffy puppy with bad teeth. [Rachel reaches for Angel's head.] No, not the hair. Never the hair.
[as Rachel.] But there must be some way I can show my appreciation?
[as Angel.] No, helping those in need's my job, and working up a load of sexual tension and prancing away like a magnificent poof is truly thanks enough.
[as Rachel.] I understand. I have a nephew who is gay, so...
[as Angel.] Say no more. Evil's still afoot. And I'm almost out of that nancy-boy hair-gel I like so much. Quickly, to the Angel-mobile, away.
[Spike crashes to the floor and sits up looking furious.]
Spike: Right! We are gonna set some ground rules. Number one - don't hit me in the face. Number two - when I hit you in the face, you tell me how it feels, so I can write that on my clipboard. Number three [holds up the clipboard.] don't touch my clipboard.
Heartthrob - S3-E1
Wesley: It's sad. The only way some people can find a purpose in life is by becoming obsessed with demons. By the way, Gunn, technically that wasn't a Lurite, it was a Murite, a subspecies of the Lurite. The male sports a small telltale fin just behind the third shoulder.
Gunn: I'm so glad to know we're not the sad people obsessed with demons.
Answer: Everybody including Angel saw her. After helping them and then being left alone to talk to Angel, Cordelia says that the Powers That Be let her come back one more time to help them. After Angel gets a call saying that she died, he realises that it was her spirit that was helping them the entire time.
