Angel, Season 1

[Wesley has just shown Cordelia a news clipping about a murdered girl.]

Wesley:
I think you'd better sit down. While executing my duties as Watcher in Sunnydale, I did extensive research, specifically on Angel, given his uncomfortable proximity to the Slayer.

Cordelia:
He looked pretty comfortable to me.

Wesley:
When I saw this story today, it rang chillingly familiar. So, I reacquainted myself with certain facts, confirming, I'm sorry to say, my grim suspicions. In the late 1700s, it was Angelus' custom to sign his victims by carving a Christian cross into their left cheek. He liked to let people know he'd been there.

Cordelia:
Okay. You get to leave now. You're not going to come in here and accuse Angel like this.

Wesley:
Cordelia...

Cordelia:
No! I don't care how many files you have about all the horrible things he did back in the powdered-wig days! He is good now. And he is my friend, and nothing you or anyone else can say will make me turn on a friend!

Angel:
Cordelia, he's right.

Cordelia:
[to Wes] You stake him and I'll cut his head off.
