Wesley Wyndam-Pryce

(S01E11) Cordelia: (to Wesley): I don't care how many files you have on all the horrible things that 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: You stake him, and I'll cut his head off.

There wasn't much revelation of Angel's infamous past in the first half of the first season of Angel. We had appearances from both Spike and Buffy (of Buffy the Vampire Slayer fame) to represent his recent past, but most of the episodes featured evil from the present. However, with this episode we took a look far back into the past of Angel, actually back to Angelus to be more specific, and the consequences of his evil doings in the bad ol' days.
