The Yellow-Eyed Demon
At the house, Dean snaps at Bobby and jumps up, and there's the distinctive noise of a chair falling to the floor. However, after he finishes apologizing to Bobby, Dean walks back to the chair, which is standing upright again.
When Dean kisses the female demon to seal the deal, his head is tilted to the left. However, the camera cuts to a shot behind him, and his head is instantly tilted to the right.
When Sam and Dean stand over the Yellow-Eyed Demon's corpse, Dean puts the Colt in his pocket with the barrel up. When he walks back to the Impala and takes it out of his pocket, the barrel is down.
During the opening scene, if you look closely, Sam appears to be breathing, even though he is supposedly "dead".
It is odd that the pentagram in the Devil's Gate is turned upright (direction for protection) when the Gate is opened, but when it is closed, the pentagram is upside down (meaning the exact opposite of an upright pentagram).
Why didn't the Yellow-Eyed Demon just ask Jake to simply destroy a small portion of the railroad lines? It would have broken the pentagram, and permitted him to cross it himself--and allowed him to not have to entrust the Colt to Jake.
When the Yellow-Eyed Demon is talking to Dean you can notice some big light rings, it is like projectors that were used to illuminate the scene.
It is the second time the song Carry on My Wayward Son by Kansas is used in the show. It was first used in "Salvation" (season 1 episode 21) over the opening sequence showing what previously happened during the first season. The song is used again in the opening sequence of this episode showing what previously happened during the first two seasons.
Trivia: Dean said "We've got work to do" as he closed the trunk of the Impala. Sam said the same thing as he shut the Impala's trunk at the end of the pilot episode. Not to mention that, in the pilot episode, Sam was standing on the left and Dean was standing on the right (and Sam was the one who dropped the gun into the trunk and closed it); in the season finale of this season, the brothers were standing on opposite sides and Dean was the one who dropped the gun into the trunk and closed it.
Yellow-Eyed Demon: If you're gonna open that crypt for me, you're gonna need a key. (pulls out the Colt)
Jake: A gun?
Yellow-Eyed Demon: Oh, this isn't just any gun, Jake. This is the only gun in the whole universe that can shoot me dead.
Jake: Is that so?
Yellow-Eyed Demon: Yep. Here, take it. (Jake aims the gun at the Yellow-Eyed Demon) Oh my. I'm shocked at this unforeseen turn of events.
Dean: (to Sam's body) When you were little, couldn't have been more than five, you just started asking questions. How come we didn't have a mom. Why did we always have to move around. Where'd Dad go. Take off for days at a time. I remember I begged you to quit asking, Sammy. "You don't want to know." I just wanted you to be a kid. Just for a little while longer. Always tried to protect you. Keep you safe. Dad didn't even have to tell me. It's always my responsibility, you know? It's like I had one job. I had one job, and I screwed it up. I blew it, and for that, I'm sorry. I guess that's what I do. I let down the people I love. Y'know, I let Dad down, and now I guess I'm just supposed to let you down, too. How can I? How am I supposed to live with that? What am I supposed to do? Sammy? What am I supposed to do?
Female Demon: Then no deal.
Female Demon: Fine. Make sure you bury Sam before he starts stinking up the joint.
Dean: Stop, Sam, stop! Damn it. 'Kay, you almost died in there. What would I have… can't you just take care of yourself for a little bit? Huh, just a little bit?
Sam: I'm sorry, no.
Dean: Dad brought me back, Bobby, I'm not even supposed to be here. At least this way something good can come out of it, y'know, it's like my life can mean something.
Bobby: What? And it didn't before? Have you got that low an opinion of yourself? Are you that screwed in the head?
Dean: Don't get mad at me. Don't you do that. I had to. I had to look out for you. That's my job!
Sam: And what do you think my job is?
Sam: You saved my life, over and over. I mean, you sacrifice everything for me, don't you think I'd do the same thing for you? You're my big brother. There's nothing I wouldn't do for you. I don't care what it takes, I'm gonna get you out of this. I guess I gotta save your ass for a change.
Yellow-Eyed Demon: So, Dean. I gotta thank you. You see, demons can't resurrect people unless a deal is made. I know, red tape, it'll make you nuts. But thanks to you, Sammy's back in rotation. Now, I wasn't counting on that, but I'm glad. I liked him better than Jake anyhow.
Yellow-Eyed Demon: (flings Sam into a tree) I'll get to you in a minute, champ, but I'm proud of you! I knew you had it in you.
Yellow-Eyed Demon: Boys shouldn't play with Daddy's guns.
Jake: You were dead. I killed you.
Sam: Yeah? Well, next time finish the job.
Dean: Ellen what happened, how'd you get out?
Ellen: I wasn't supposed to; I was supposed to be in there with everybody else. But we ran out of pretzels, of all things. It was just dumb luck.
Dean: What do I have to do?
Female Demon: First of all, quit groveling. Needy guys are such a turn-off.
Yellow-Eyed Demon: I'll make certain that they both live long enough to know the chewy taste of their own intestines.
Bobby: I could throttle you.
Dean: What? And send me downstairs ahead of schedule?
Ellen: Well, the Yellow-Eyed Demon might be dead, but a lot more got through that gate.
Dean: How many you think?
Sam: A hundred, maybe two hundred. It's an army... he's unleashed an army.
Bobby: Hope to hell you boys are ready. Cause the war has just begun.
Bobby: Something big is going down. End of the world big.
Dean: Well, then let it end!
Bobby: You don't mean that.
Dean: You don't think so? You don't think I've given enough? You don't think I've paid enough? I'm done with it. All of it. If you know what's good for you, you turn around, you get the hell out of here. Go!
Dean: (after killing the Yellow-Eyed Demon) Check that off the to-do list.
Sam: (about the demon being dead) I kinda can't believe it, Dean. I mean our whole lives, everything has been prepping for this and now I... I kinda don't know what to say.
Dean: I do. (he kneels over the demon's body) That was for our mom, you son of a bitch.
Yellow-Eyed Demon: (to Dean) You of all people should know that what's dead should stay dead. Anyway, thanks a bunch. I knew I kept you alive for some reason. Until now, anyway. I couldn't have done it without your pathetic, self-loathing, self-destructive desire to sacrifice yourself for your family.
Bobby: (staring at the unlocking vault) Oh no.
Ellen: Bobby, what is it?
Bobby: It's Hell. Take cover, now!
Ellen: (about the Roadhouse fire) A lot of good people died in there, and I got to live. Lucky me.
Jake: Go to Hell.
Yellow-Eyed Demon: Been there, done that.
