Faith states that she went to prison for murder 2 with a sentence of 25 to life. This means she was convicted for the murder of the Deputy Mayor but wasn't convicted for the murder of the vulcanologist in season 3 of Buffy the Vampire Slayer or the assault on the man at the bus depot in season 1 of Angel.
When The Beast lifts Faith over his head, you can see where the safety line is attached to the back of her jacket.
The bit where the stunt players fall out the window, they land, and the camera does a cut to show us the actors moving off-screen, is pretty badly done - it's clear when the switch is made and who's who.
Angelus is clearly not strangling the jowl-demon or even holding its neck very tightly when he threatens it for information.
Fred uses a belt to make a tourniquet for Cordy's leg but after Cordy is there to see Lilah's body, the tourniquet disappears.
Why didn't Wesley tell Faith that weapons, particularly crossbows, are useless against the Beast? That's the first thing that Faith uses against the creature and of course, it doesn't do anything.
When Faith and Wesley hit the car and get off during their escape, Faith starts leading Wesley to his car. How would she know where it is?
Wesley: We need you.
Faith: Well... Hate to wet the paper for you Wes, but I'm kind of unavailable right now. Maybe you wanna check back in a few decades when my parole comes up!
Connor: Magic again. You people rely way to much on that junk.
Wesley: We use whatever tools we have.
Connor: Yeah, only it never really works the way it's supposed to.
Wesley: Do you really think that's what I was thinking?
Imaginary Lilah: Honey, I'm not even here. I'm just a figment of your devilishly handsome brain. So, clearly, it's what you thought.
(After the beast is killed)
Angelus: Ahh...crap. You mean killing the beast really brings back the sun? I thought that was Angel's retarded fantasy.
Angelus: And I don't like being kept in the dark... well, figuratively anyway.
Angelus: And if your boss was half as smart as he thinks he is, he knows I won't take orders from a lackey.
Angelus: You don't like lackey? How about uh; toady? or lickspittle? Ahh, lickspittle's nice. Oh wait, I got it, flunky! That's it! You're just a big, stupid, butt ugly, slow moving, flunky!
Faith: Hey, nobody make a move, until I...
(vampire that looks a lot like Angelus jumps at Connor, he decapitates him)
Faith: (pushing Connor against a wall) Are you deficient?
Angelus: Smile, Faith, thought you'd enjoy a threesome!
Faith: (after Wesley's test) It's like riding a biker.
(Some members of the fang gang spot Angelus feeding on Lilah)
Angelus: Ah, guys. It's not what it looks like. (Looks down at Lilah and then back up) She was kinda tarty anyway. Know what I mean, Wes?
Cordy: Faith! What the hell is she doing here?
Faith: Nice to see you too, Cor.
Wes: She's here to help.
Cordy: Oh gee, uh, that's great oh, wait a sec, wasn't she convicted of murder and sent to a state correctional facility for like a gazillion years?
Faith: Murder 2, 25 years to life. For the record.
Cordy: So now you brought psycho Slayer out of retirement to kill Angelus?
Faith: Are you a murderer? 'Cause I am.
Lorne: We followed the recipe. Should be cake.
Connor: How long does it take to chop off Lilah's head?
Prison Guard: (to Faith) Hey, caught us by suprise. I mean, who'd be crazy enough to try to take you out?
Faith: Can I ask, what the hell have you people been doing?
Wesley: ..I've changed my mind.
Connor: Change it back!
Cordelia: A weakness for Slayers. You really are his son.
Lilah: That body's not going to dismember itself, you know.
Demon: (to Angelus) Whoa! You're him. Talking to me. Not usually impressed by vampires, but this is such an honor. Hey, could you sign a little something to my hellspawn? Make it out to Ashley.
Angelus: That's right, brothers and sisters - the rumors are true. Angel has left the building and I am back. But hey, I'm no different from the next guy. I put my victim's skin on one leg at a time.
Connor: I know what I have to do! Angel told me if anything happened to kill him.
Lorne: Oh! Now you listen to him!
Faith: Are you okay?
Wesley: Five by five!
Angelus: Hi, Dawn! Yeah, it's me! Is your sister home? She is... (hangs up the phone) Pfew, it's the other one.
Andy Hallett (Lorne) is credited as "Special Guest Star Andy Hallett."
Though Dawn and Angel know each other, and have even appeared in several Buffy episodes together, their phone call is the first, and only, time during either series that they ever interact on-screen.
This episode features "Last Comic Standing" contestant Alonzo Bodden as the Prison Guard that talks to Faith after the attempt on her life.
The song in the background when Angelus is in the bar is the same one used when the WB first released the promo for Angel.
Lorne: Ding, Dong, The Beast is dead.
This is a twist to "Ding, dong, the witch is dead" said by the Munchkins of Munchkinland in The Wizard of Oz, said in regards to the death of the Wicked Witch of the East.
Angelus: The question is, what do you do hotshot? What do you do?
This is a paraphrase of the line uttered by Dennis Hopper in the movie Speed: "Pop quiz, hotshot. There's a bomb on a bus. Once the bus goes 50 miles an hour, the bomb is armed. If it drops below 50, it blows up. What do you do? What do you do?"
One version of the screenplay for Speed was written by Joss Whedon.
