At the end of the fight scene between Ruby and Dean and Ruby becomes stuck in the Devils Trap, we can see blood over and around her teeth. When the shot cuts to Dean walking up the stairs and Ruby is yelling at Dean, there is no blood.
When the Hellhound is tearing up Dean's chest, there is no sign of the tattoos he and Sam had during "Jus in Bello."
Trivia: Both Bela and Dean's last words were "bitch."
In the scene where Ruby and the Winchester brothers fight, the shot of Dean falling down when Ruby kicks him in the head is reused as the shot of him falling down when she head-butts him; it is frame-for-frame identical. Further, he is clearly holding her knife in his right hand held in front of him (although it disappears when he picks himself up), yet she did not notice even though she is looking right at him-both times.
Dean: (about Ruby) C'mon man, she is the Miss Universe of lying skanks!
Ruby: I want Lilith dead.
Ruby: I've told you why.
Dean: Oh right, because you were human once, and you liked kittens, and long walks on the beach!
Ruby: You know, I am so sick of proving myself to you. You want to save yourself, this is how, you dumb spineless dick!
(Dean punches her)
Bobby: (to Dean) Family don't end with blood, boy.
Dean: I'm sorry. I mean, this is all my fault. I know that. What you're doing...it's not gonna save me. It's only gonna kill you.
Sam: Then what am I supposed to do?
Dean: Sam, remember what Dad taught you, okay? Hey, remember what I taught you.
Dean: Sam, we are not gonna make the same mistake all over again.
Sam: You said that, but what does that even mean?
Dean: Don't you see a pattern here? Dad's deal, my deal, now this? I mean, every time one of us is up the creek; the other is begging to sell their soul.
Bobby: Right name, right ritual, ain't nothing you can't suss out.
Sam: Like the town Lilith's in?
Bobby: Kid, when I get done, we'll know the street.
Dean: Ruby's just jerking your chain down the road. You know what it's paved with, and you know where it's going.
Dean: Bon Jovi rocks. On occasion.
Sam: You know if this doesn't go the way we want, I want you to know that...
Dean: Nooo, no, no, no, no, no.
Sam: No what?
Dean: You're not gonna bust out the misty goodbye speech, okay? I mean, if this is my last day on Earth, I do not want it to be socially awkward.
Bobby: (hands Dean the distributor cap) I'll follow. Don't be stopping to pee every ten minutes, either!
Dean: Hey, why don't we just make a TJ-run, you know? Some señoritas, cervezas, we could.. what's Spanish for donkey-show?
Sam: So, if we do save you, let's never do that.
Dean: When that bitch breathes, the air comes out crooked.
Ruby: I wish I could be there, Dean! I wish I could smell the flesh sizzle off your bones. I wish I could be there to hear you scream!
Dean: And I wish you'd shut your piehole, but we don't always get what we want.
Dean: What do you think?
Sam: I think you totally should have been jamming Eye of the Tiger right there.
Dean: Oh, bite me. I totally rehearsed that speech, too.
Dean: We've got the knife.
Bobby: And you intend to use it without me. Do I look like a ditchable prom date to you?
Dean: Nothing. I just couldn't see you before, but you are one ugly broad.
Sam: Then what am I supposed to do?
Dean: Keep fighting. And take care of my wheels.
Bobby: Well, you got just over five hours to go. You're piercing the veil, Dean, glimpsing the "b" side.
Dean: Little less New Agey, please.
Bobby: You're almost hell's bitch, so you can see hell's other bitches.
Dean: Thank you.
Ruby: You know, phones work too. Hey, Sam. How's tricks?
Sam: How do you get around so fast?
Ruby: I got the Super Bowl jet pack.
Dean: Well, just cause I got to die doesn't mean you have to, okay? Either we go in smart or we don't go in at all.
Sam: Okay, fine. That's the case, I have the answer.
Dean: You do?
Sam: Yeah. A surefire way to confirm it's Lilith and a way to get us a bona fide demon-killing Ginsu.
Bobby: Ain't you just bringing down the room.
Dean: Well, it's a gift.
Bobby: (looking down at policeman's body) What the hell happened over here?
Sam: Dean just killed a demon. How'd you know?
Dean: I just knew. I could see its face... its real face, under that one.
Bobby: Tell me. How many hallucinations have you had so far?
Dean: How'd you know?
Bobby: Because that's what happens when you've got hell hounds on your butt. And because I'm smart.
Music: Carry On Wayward Son (Kansas), Wanted Dead Or Alive (Bon Jovi)
Carry On Wayward Son by Kansas, used for the recap at the beginning of the episode, has been used in all three season finales.

Dean: This is a terrific plan. I'm excited to be a part of it!
This is nearly word for word what Peter Venkman said when Egon and Ray came up with the "Cross The Streams" plan to defeat Gozier in Ghostbusters.
Dean: Hell, she probably wants you to become her little Antichrist Superstar.
Referencing Marilyn Manson's second album, Antichrist Superstar (1996). The concept album in turn referenced the musical Jesus Christ Superstar, originally released as a rock album in 1970 by Tim Rice and Andrew Lloyd-Webber then made into a musical. "Angel With the Scabbed Wings" had a similar riff to Lloyd-Webber's score.
Dean: What, are you gonna give her the Carrie stare and Lilith goes poof?
Referencing the novel Carrie by Stephen King, which tells the tale of a high school girl with telekinetic powers, who goes berserk during her high school prom and kills most of the students. Later made into a movie by Brian De Palma in 1976 starring Sissy Spacek. In 2002, a remake was made starring Angela Bettis.
Squad Car Number:
The squad car is 54. When the dispatcher eventually tries to reach the cop on the radio, they will likely say "Car 54, where are you?" The B&W comedy series of the same name aired from 1961 to 1963 and starred Joe E. Ross and Fred Gwynn.
Dean: Our slutty little Yoda.
This is a reference to the Jedi Master Yoda from the Star Wars movies. Yoda was famous for often spouting words of wisdom.
