-----Summary:
Galway, Ireland, 1753: Angel (then named Liam) is caught by his father as he tries to seduce their servant. His father berates him for his debauchery, and for trying to corrupt the girl. When Liam talks back, his father slaps him across the face, saying he's ashamed to call him his son.Angel remembers this scene as he fights a demon in a subway tunnel. As Angel finishes it off, Kate arrives on the scene. Outside the tunnel, police are taking statements from witnesses; Kate spots her father there. He says he heard there was a situation, and thought he'd stop by. Kate thinks he's checking up on her.

Flash back to Ireland. Angel's remembering a bar fight, and two lovely lasses watching him and smiling. He's remembering smiling back at one when Cordelia snaps him back to the present. Wesley has checked the books, and found the demon in the tunnel, but he's curious - all the books say it should have been a peaceful, balancing demon. What would make a peaceful demon attack a subway train full of commuters? Angel visits Kate to see what she knows. Since the demon's dead, though, she'd rather just forget about it.

While Cordelia and Wesley find the demon's body and take a piece to run tests, Angel follows a suspicious-looking delivery guy who was on that train. While he's tracking him, the guy receives a phone call and drives off. Angel follows him to an apartment building, where he picks up a package - from Kate's father.

After the delivery guy is gone, Angel knocks on Mr. Lockley's door, and accuses him of removing something from the crime scene that somebody didn't want the police to find. He denies it, but Angel warns him - he will find out what's going on. When Mr. Lockley slams his door, Angel has another flashback - his father is kicking him out of the house. Later, when he walks into the arms of Darla, one of the girls who watched the bar fight, she takes a bite from his neck - she's a vampire. Slumped to his knees at her feet, Liam's face falls into her chest, where she's spread some of his blood. And he tastes it.

Back at Angel's (in the present again), Wesley is dissecting the piece of demon, and confirms the species. He also finds a substance in its system, a drug, that would explain why it attacked the subway train - it was jonesing for more. Then Cordelia, who's been tracking (and videotaping) the delivery guy, pops in. She has a tape of him at Kel's Exotic Auto, which Angel thinks is the drug source.

Meanwhile, at Kel's, Kate's father arrives. He's been smuggling for the people there, but he thought it was just auto parts - he doesn't know what's in the other packages. And he tells them Angel's been looking into their operation. After Mr. Lockley leaves, the boss appears. He's a bit demon, and he wants Angel and Mr. Lockley both killed.

Flash back to old tyme Ireland: Liam's family weeps at a funeral - Liam's funeral. But when Darla visits his grave later that night, he emerges a vampire. When he then goes to visit his father, he's out for blood.

Flash forward to L.A.: Angel's headed out to investigate Kel's, but he doesn't get far - two of the "peaceful" demons break into the office. Angel returns, with a vial of the drug, which he uses as bait. He tosses one demon out the window, and pumps the other for information.

Things look bad for Mr. Lockley. Angel calls Kate, telling her to go to her father's place and get him out of there; he's on his way. At Mr. Lockley's apartment, the two fellows from Kel's have already arrived. Then Angel knocks, and asks Mr. Lockley to invite him in; he tells Angel to leave. That's when the two guys turn vampire. Since Angel wasn't invited in, he can't enter until Mr. Lockley is dead; soon enough, he is. Angel leaps in, fashions a stake from a chair leg and slays one of the vampires, but the other gets away, just as Kate arrives to find her father dead. In the wreckage of her father's apartment, she finds a business card from Kel's. Angry, she heads straight there, and begins shooting. Then she pulls out a stake, and begins slaying. Soon the demon boss appears. But so does Angel, armed for battle. Together, he and Kate slay the crowd, but Kate, still upset, isn't very appreciative.

Flashing back to the past, Angel reviews the carnage of his own family, which he has created. He feels quite powerful, but Darla reminds him that while his victory over his father took but moments, his father's disapproval will haunt him for lifetimes.

-----Quotes:

Angel (as Liam): Everyone gets corrupted. But I find some forms of corruption are more pleasant.

Kate: (sees dead demon body) Well, I guess I can forget about reading him his rights.

Kate: So they...so they die then.
Angel: Yeah.
Kate: Sorry, I guess I'm still having a little trouble with this "otherworldy" stuff.
Angel: Right...although demon's aren't technically otherworldly. I mean, in fact, they were here (Kate walks off) ...first.

Kate: You've been sitting in your apartment listening to that police scanner, haven't you?
Trevor Lockley: Nothing on cable anyway.

Kate: No, you don't get to do that.
Angel: What?
Kate: Kill a demon in front of me and then act like we're gonna have a cappuccino together. It doesn't work that way.
Angel: How does it work?
Kate: I'm not convinced it does.

Kate: No offense. I think you're probably a pretty decent guy for a...you know, what you are. But let's keep this strictly business.

Darla (regarding Angel): He's magnificent.
Barmaid: Oh, yeah, God's gift alright.
Darla: Really? I've never known God to be so generous.
Barmaid: Oh, his lies sound pretty when the stars are out. But he forgets every promise he's made when the sun comes up again.
Darla: That wouldn't really be a problem for me, actually.

Cordelia: The installation guy said it should be something easy to remember, like...my birthday.
Angel: I don't know your birthday.
Cordelia: Yeah, tell me something you don't know that I don't know. But after 11 1/2 months of punching it in to this, you won't have any excuses.

Angel: This thing was a fighter.
Wesley: Not if it was a Kwahini, it wasn't. At least, not a fighter by nature. They're incredibly articulate, gentle creatures. Not even capable of the kind of power and strength you described.
Cordelia: Maybe it was just having a bad skanky rag day.

Angel: It's about that demon from this morning...
Kate: If you insist on talking about this stuff, could you please not say that word? It makes me... It makes me, I don't know, just uncomfortable. Just say... Evil Thing, okay?

Angel: It's just that the ... uh... Evil Thing -- turns out that it wasn't an evil Thing.
Kate: The Evil Thing wasn't an evil Thing?
Angel: Well, it was an Evil Thing, in terms of that word. It just wasn't an evil Evil Thing.
Kate: There are not-evil Evil Things?
Angel: Well, yeah.

Angel: I think that the demon...I think the *train* may have been targeted for a reason.
Kate: An Evil Thing needs a reason?

Kate: Angel, there's nothing here. Your not evil Evil Thing was just evil, okay?

Trevor Lockley: Kind of a Mexican name, isn't it? Angel?

Trevor Lockley: What's wrong with him?
Kate: Nothing.
Trevor Lockley: Must be something wrong with him. He married?
Kate: No.
Trevor Lockley: West Hollywood?
Kate: Daddy, no! Angel's just not my type. Or I'm not his type. There's definitely a type involved, and it's the wrong one.

Trevor Lockley: He made an impression.
Kate: You like him?
Trevor Lockley: No, not really.

Angel: So, you're back.
Cordelia: Very good, Mister I-can't-tail-the-suspect-during-the-day- because-I'll-burst-into-flames Private Eye.

Cordelia: First off, I hate following detail.
Wesley: The voyeuristic aspect is rather unseemly.
Cordelia: Oh! Can I mention traffic? And parking? Or the complete lack of it?
Angel: Not like in the movies, is it?

Angel: Sometimes the price we end up paying for one bad choice isn't commensurate with the offense.

Angel: Strange. Somehow, you seemed taller when I was alive.

Angel: You said I'd never amount to anything. Oh, you were wrong. (Morphs) You see, father? I have made something of myself after all.

Vampire: Looks like you're not welcome here, bro.
Angel: He dies, and the very instant his soul leaves his body, I'm through this door, and I kill you both.

Wesley: What happened to calmly, cautiously, and deliberately investigating before rushing in?
Angel: That was Plan A. We've since moved on to Plan B.
Wesley: And Plan B is?
Angel: (brandishing an axe) Do I really have to explain it to you, Wesley?

Demon: You don't understand what stands before you!
Angel: Oh... a big ugly drug-running demon who thinks he's a lot scarier than really he is, maybe? Yeah, she knows.

Demon: You're dead!
Angel: I'm already dead. (chops his head off) Welcome to the club.

Angel: Never trust an evil Evil Thing.

Angel: Kate, I know that what happened with your father...
Kate: My father was human. And you don't know anything about that.

Darla: Your victory over him took but moments.
Angel: Yes.
Darla: But his defeat of you will last lifetimes.
Angel: What are you talking about? He can't defeat me now.
Darla: Nor can he ever approve of you. In this world or any other. What we once were informs all that we have become. The same love will infect our hearts, even if they no longer beat. Simple death won't change that.
Angel: Love. Is this the work of love?
Darla: Darling boy. So young. Still so very young.
