In Sam's first nightmare flashback, there are drops of blood on his forehead before he opens his eyes and sees Jessica on the ceiling, but in his second nightmare flashback, there is only one drop of blood on his forehead. The dreams were lifted from two different takes of the scene.
As the brothers drive out of town and Sam sees the vision of Jessica, she is standing across the street from George's Taverna in Steveston. The Greek restaurant is located at 130-3760 Moncton St., in Steveston (Richmond), BC, and definitely isn't in Toledo, Ohio.
When Sam and Dean enter the Shoemaker home at the funeral reception, at the 8:09 mark, there is a woman just inside the door holding a coffee cup. As the brothers walk away, she starts to follow them. However, in the next shot, she is standing still and facing away from them.
In "Pilot," Jessica was on the ceiling on fire in a completely different nightgown/nightie to the one she was wearing when Sam saw her ghost on the street.
While Sam is inside breaking all of the mirrors Dean is outside talking to the police. It seems impossible that the cops didn't hear what was going on inside the shop, Sam wasn't exactly being quiet.
Officer: Hold it!
Dean: Whoa, whoa, whoa, guys. False alarm. I tripped the system.
Officer: Who are you?
Dean: I'm the boss's kid.
Officer: You're Mr. Yamishiro's kid?
Reflection: You never told her the truth--who you really were. But it's more than that, isn't it? Those nightmares you've been having of Jessica dying, screaming, burning--You had them for days before she died. Didn't you? You were so desperate to be normal, to believe they were just dreams. How could you ignore them like that? How could you leave her alone to die? You dreamt it would happen!
Dean: I don't what?
Sam: You don't know all about it. I haven't told you everything.
Dean: What're you talking about?
Sam: Well it wouldn't really be a secret if I told you, would it?
Dean: Well, who's gonna summon her?
Sam: I will. She'll come after me.
Dean: You know what, that's it. This is about Jessica, isn't it? You think that's your dirty little secret that you killed her somehow? Sam, this has got to stop, man. I mean, the nightmares and calling her name out in the middle of the night—-it's gonna kill you. Now listen to me-—It wasn't your fault. If you wanna blame something, then blame the thing that killed her. Or hell, why don't you take a swing at me? I mean I'm the one that dragged you away from her in the first place.
Sam: So we gotta search local newspapers, public records as far back as they go. See if we can find the Mary who fits the bill.
Dean: Well, that sounds annoying.
Sam: No, it won't be so bad, uh, as long as we... (looks at the computers, which have signs on them saying "OUT OF ORDER") ...huh. I take it back. This will be very annoying.
Sam: Might not be one of ours. It might be just some freak medical thing.
Dean: How many times in Dad's long, varied career has it actually been a freak medical thing? And not some sign of an awful supernatural death?
Sam: Uh, almost never.
Sam: Find anything?
Dean: Oh, besides a whole new level of frustration? No. A few local women, a Laura and a Catherine, committed suicide in front of a mirror. And a giant mirror fell on a guy named Dave. But, uh, no Mary.
Sam: Why'd you let me fall asleep?
Dean: Because I'm an awesome brother. So, what'd you dream about?
Sam: Lollipops and candy canes.
Dean: Yeah, sure.
Sam: But the eyes. What would cause something like that?
Coroner: Capillaries combust? Uh... I see a lot of bloodshot eyes with stroke victims.
Dean: Yeah, you ever see exploding eyeballs?
Coroner: Yeah, that's a first for me.
Dean: Hey, Sam?
Dean: Now that this is all over, I want you to tell me what that secret was.
Sam: Look, you're my brother and I'd die for you. But there are some things I need to keep to myself.
Dean: Sammy! Sammy!
Sam: It's Sam.
Charlie: I'm insane, right?
Dean: No, you're not insane.
Charlie: God, that makes me feel so much worse.
Dean: Hey, Sam?
Dean : This has gotta be like, what, 600 hundred years bad luck?
Dean: Dude, I earned that money.
Sam: You won it in a poker game!
Canadian actor and stunt artist Dan Shea has an uncredited appearance as the second police officer who approaches Dean outside the antique shop. He is clearly visible at the 37:07 mark, although he has no dialogue.
At the end of the episode, when Blood Mary exits her mirror, both Sam's and Dean's eyes bleed. Creator Eric Kripke stated: "There is something in his past - we've always known it. It's been the core of the character from the time we created him."

This episode is set in Toledo, Ohio. This is the hometown of Eric Kripke and Adrianne Palicki (Jessica Lee Moore).
Many viewers were unhappy that the animation of Bloody Mary looked so much like the creepy girl in The Ring. A complaint letter was even written and published in TV Guide (October 31 - November 6, 2005).
Music: Laugh, I Nearly Died by The Rolling Stones, Rock of Ages by Def Leppard, and Sugar, We're Going Down by Fall Out Boy.
Dean Do I look like Paris Hilton?
Said as Sam pointed a videocam on his brother. This is in reference to Paris' various videotaped sexual escapades with at least two ex-boyfriends. Also, Hilton and Jared Padalecki both starred in the 2005 feature film, House of Wax.
Some of the elements in this episode are very similar to the horror movie The Ring:
- the small oval mirror where a woman with long hair over her face can be seen
- Bloody Mary climbing out of the mirror on her hands and knees (in the movie, Samara climbs out of a television)
- jerky, stop-motion type movement when she moves
- Mary's appearance is very similar to The Ring's Samara, in that she has long dark hair that obscures her face and wears a long white dress.
