In suburban Nebraska, a group of partying high school teens jokingly dare their friend Charlie (guest star Marnette Patterson) to look into the mirror and repeat 'Bloody Mary, Bloody Mary, Bloody Mary," not knowing this will unleash a series of mysterious murders. Sam (Jared Padalecki) and Dean (Jensen Ackles) realize that Bloody Mary has the power to travel through all reflective surfaces when she is hunting a victim. Worried that teens are accidentally summoning Bloody Mary, Sam and Dean race to destroy the violent spirit before she can kill again.
- Dean: Do I look like Paris Hilton?
- Charlie: I'm insane, right?
- Dean: No. You're not insane.
- Charlie: God, that makes me feel so much worse.
- What is Sam's secret? What did he know before Jessica died?
- Sam reveals that he has not told Dean everything about why he's having nightmares about Jess.
- 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.
- The Rolling Stones - "Laugh, I Nearly Died"
- Fall Out Boy - "Sugar, We're Going Down"
- Def Leppard - "Rock of Ages"
- Split Habit - "Merry Go Round"
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'sSamara, in that she has long dark hair that obscures her face and wears a long white dress.
A demonic shape-shifter adopts the likeness of Sam's college buddy to commit a gruesome murder. when the brothers investigate, the being "borrows" Dean's form to continue its killing spree.
