In a previous episode we find out that, as CEO of Wolfram & Hart, Angel has a helicopter at his disposal. Therefore it seems illogical that when he was trying to beat Spike to the cup, he took a car, as opposed to the faster helicopter.
The dead bride in the carriage blinks twice when Angelus puts his arm around her.
This may indicate that she is not actually dead, but rather fading in and out of consciousness due to blood loss.
Rutherford Sirk makes a comment about comparing the King James Bible to the "original Aramaic or Hebrew." Only a few verses are written in Aramaic throughout the entire bible. Aramaic was the language most likely spoken by Jesus and his followers, but it was not the language of the writers of the New Testament, which was Greek. It's most appropriate to say "original Greek or Hebrew."
When Harmony and Spike are having their "nooner" and Harmony bites him, Spike just jumps off without having time to either pull up his pants or zip up. But when the angle has changed a couple times, you see that his pants are on, zipped up and buttoned. Shirt tucked in and all.
The blood on Spike's nose in the beginning seems to appear and disappear every time the camera cuts back and forth from him.
Spike: You never knew the real me. You were too busy trying to see your own reflection.
Drusilla: (to Angelus) Look what I made. It's called Willy.
Angel: (Angel on phone) You took my Viper.
Spike: My Viper now, mate. Possession's nine-tenths. Oughta know that, runnin' a law firm and such.
Angelus: I like this one. We're gonna be the best of friends.
(flashes forward in time to present day)
Angel: (angrily) Spike, get the hell away from me.
Spike: Drusilla may have sired me but you (Angel) made me a monster.
(Spike grabs Harmony and kisses her)
Harmony: Get off!
Spike: That's the idea.
Gunn: I just went to the white room to see what the big cat had to say.
Gunn: Cat's gone.
Gunn: The white room, too. Elevator just opened up into a howling abyss. You ever heard a howling abyss? Terrible sound.
Angel: Trust me, I read the prophecy!
(Cut to Sirk's office)
Sirk: You didn't read the prophecy.
Angel: I didn't?
Eve: (About prophecy) So there's a cup.
Spike: Perpetual torment? Just know that's not gonna taste very good.
Spike: Take a long look, hero. I'm nothing like you!
Angel: No. You're less. That's why Buffy never really loved you, because you weren't me.
Spike: Guess that means she was thinking about you...all those times I was puttin' it to her.
Angel: Is that what you think you are, a hero?
Spike: Saved the world, didn't I?
Angel: Once. Talk to me after you've done it a couple more times.
William (Spike): It's like she's still got a bit of a child in her.
Angelus: Perhaps two or three by now.
Eve: This town might not be big enough for the both of you.
Spike: Well, screw this town, then. Screw this devil's funhouse, Angel, and screw you for good measure. I think I'll take the new flesh and bones across the pond back to Europe.
Spike: (drinks from Cup of Perpetual Torment) It's... Mountain Dew.
Gunn: (to Eve) Don't be fingering the robots.
Spike: Look at you, thinking you're the big savior fighting for truth, justice, and soccer moms. But you still can't lay flesh on a cross without smelling like bacon, can you?
Angel: Like you're any different.
Spike: Well, that's just it. I am, and you know it. You had a soul forced on you, as a curse, make you suffer for all the horrible things you'd done. But me, I fought for my soul. Went through the demon trials. Almost did me in a dozen times over, but I kept fighting 'cause I knew it was the right thing to do. It's my destiny.
Angel: Really? Heard it was just to get into a girl's pants.
Spike: At least give me Wesley's office, I mean, since he's gone.
Angel: He's not gone. He's on a leave of absence.
Spike: Yeah, right. Boo-hoo. Thought he killed his bloody father. Try staking your mother when she's coming on to you!
Harmony: Well, that explains a lot.
Angelus: You know Darla, Master's pet.
David Boreanaz was originally slated to direct this episode, but the plan had to be changed due to David's knee surgery.
This episode was involved in a FCC investigation, for possible "sufficiently graphic or explicit" scenes- one where Angel is moving his hips and another involving two vampires biting each other during love making. The FCC rejected the complaint.
David and Steven had an argument when writing "Destiny" about who should drink from the Cup. David fought for Spike to drink the Mountain Dew while Steven said Angel should win. Because David was showrunner this season, that may be why his part of the script won out.
This is the only episode in which Alexis Denisof (Wesley) did not appear since joining the cast in "Parting Gifts" (1.10).
Alexis Denisof (Wesley) is not in this episode. The character took a leave of absence after the events with his "father" in the last episode. Alexis was getting married to former Buffy the Vampire Slayer actress Alyson Hannigan the week of filming.
Christian Kane's name is omitted from the opening credits to keep Lindsey's "surprise" appearance a secret.
The song Spike plays in the car is called, "Too Drunk to Fuck" by the Dead Kennedys.
Eve: Trouble with a capital T and that rhymes with P and that stands for prophecy
This is a reference to the Meredith Willson book and movie, The Music Man. There is a part of the story where the townspeople are concerned that some people are playing too much pool (billiards). In the original line, "prophecy" is replaced by "pool."
