From CityOfAngel.com:
CYBERNETIC GENETICS -- The offices of Wolfram & Hart are under attack by cyborg assassins who are seeking a magical device that will give them control over Angel. Meanwhile, Wesley is surprised by the unannounced arrival of his estranged father (guest star Roy Dotrice, Beauty and the Beast) who has come to evaluate Wesley for possible reacceptance to the Watcher's Council.

Fred: [discussing the cyborg] This thing really blurs the line between human and robot.
Spike: Aha! So you're not ruling out that a human being could've boffed a robot. [..beat..] Sex with robots is more common than most people think.
Spike: Daddy, eh? I always though Wesley was grown in some sort of greenhouse for dandies.
Roger: Spike.
Spike: [proudly] You've heard of me?
Roger: No, we've met. 1963, my colleagues and I fell upon you slaughtering an orphanage in Vienna. Killed 2 of my men before you escaped.
Spike: Oh.. [..beat..] how've you been?
Angel: What happened?
Spike: I can explain. Apparently, when Percy here was younger, he used to be known as "Head Boy."
Angel: Yeah, I already knew that.
Spike: Right. I have nothing else to report.
Eve: [elevator lights go out] That's odd.
Spike: I know what this is. [looks up] You'll never take me to Hell, Pavayne! [emergency lights turn on] Oh. Well, that's just something I say, when, uh.. it gets dark.
Angel: They're all trying to bring us down. The perception is that we're weak.
Wesley: No. The perception is that I'm weak. That's why they went for me.
Angel: They're wrong. You do what you have to do to protect the people around you. To do what you know is right, regadless of the cost. You know, I never really understood that. You're the guy who makes all the hard decisions, even if you have to make 'em alone.
Angel: You know.. I killed my actual Dad. It was one of the first things I did when I became a vampire.
Wesley: I hardly see how that's the same situation.
Angel: Yeah, I didn't really think that one through.
Spike: Heard what happened up top, offing your dad and all. Don't know if you know this, but, uh.. I killed my mum. Actually, I'd already killed her, and then she tried to shag me, so I had to--
Wesley: Thank you. [holds up hands] I'm.. very comforted.
Fred: Part of you knew. Even if you can't admit it to yourself, part of you knew it wasn't him.
Wesley: No. I was sure it was him. You were there. I killed my father.
Fred: He was threatening your friends.
Wesley: He was threatening you. He pointed a gun at you, Fred.. so I shot him.
