  • Season 4 Episode 9: I Know What You Did Last ...

  • When Sam starts to tell Dean the story about how Ruby saved his life, he is holding a towel to the cut he just stitched up, and his shirt sleeve is bloody from the wound. When the flashback takes a break, Sam hasn't moved from where he was sitting, but his shirt is spotless and there is no blood on his arm or towel stopping the flow.

  • When Dean and Sam leap out the window, the shot from inside shows the two brothers hitting the window simultaneously. However, when the camera cuts to the outside, Sam emerges first and Dean is considerably behind him.

  • Season 4 Episode 7: It's the Great Pumpkin, S...

  • When Sam is killing Samhain, his nose starts bleeding and the blood reaches his chin. However, in the next shot his face is clean and he starts bleeding all over again.

  • When Sam is researching in the hotel room in the beginning, he picks up the Goldthread to inspect it when he is flipping through books, and keeps it in his hand when Dean comes in. When he starts to tell Dean about the hex bag, one shot shows the Goldthread in his hand, and the very next, he picks it up from the hexbag, without having put it back.

  • When Sam and Dean ask the victim's wife how many razor blades were found she says "two on the floor, one in his stomach and was stuck in his throat." When you watch the scene where the victim spits out the razor blades, there are two on the floor but a third one is heard falling on the floor. So there should have been found at least three razor blades on the floor.

  • Trivia: When Sam tells Dean that Luke Wallace's and Jenny's deaths are linked to some spell ("Three blood sacrifices over three days...") he shows him a book. On the book an illustration can be seen. It's a Gustave Doré drawing (one of the most famous Dante's "Divina Commedia" illustrators), which represents Dante and Virgil in Hell, talking to the damned soul of the heretic Farinata Degli Uberti (see Dante's Inferno, canto 10).

  • Sam and Dean come out of their hotel room to find the Impala splattered and splotched, most likely by the astronaut boy who got no candy. However, when the brothers leave the house after having driven directly there from the hotel and the school in the middle of a crisis, it is perfectly clean.

  • Season 4 Episode 6: Yellow Fever

  • When Dean and Sam are in the mill they hear a sound coming from the locker room. As Sam opens the locker a cat comes jumping out making Dean scream like a little girl. Just before the scene ends you see Dean and Sam leave the frame with Dean laughing.

  • In the scene when Sam and Dean are invited into the sheriff's office, for the first time. Sam gets out of his chair and begins adjusting his shirt collar. But when the shot changes his hands are down to his side.

  • For some reason the closed caption says that Waylon Jenning's Slow Rollin' Low is playing in the police station when Dean and Sam go into the sheriff's office. No such music is playing.

  • Autopsies are suppose to be recorded when doing the procedure. The doctor did not record himself, instead he was talking with Sam and Dean.

  • Season 4 Episode 5: Monster Movie

  • When Sam picked the lock to enter Lucy's place, the lock knob above the handle didn't turn.

  • When Dean says this line after taking the ribbon out of his pocket to show Sam in the bar after his fight with Dracula: "This, I uh, pulled it off during the fight" his lips don't move, and the volume is different from the rest of his line, you can clearly tell this line was added in post as a voiceover.

  • When the brothers arrive in town the first night, there's a crescent moon in the sky. However, the second night when the werewolf strikes, the moon is full. The moon doesn't change phases that fast from crescent to full in a single night.

  • Season 4 Episode 4: Metamorphosis

  • The sign outside the Montgomery house reads "The Montgomery's," with an incorrectly used apostrophe.

  • Trivia: For the first time in many episodes, Sam introduces themselves as Sam and Dean Winchester, as well the Impala's license plate is once again reading the original KAZ 2Y5.

  • Season 4 Episode 3: In the Beginning

  • When Azazel kills John and promises Mary he'll arrange for "lover boy to be brought back breathin'," the actor playing John is clearly breathing.

  • Trivia: The Impala's first license plate with John Winchester is C-45P4.

  • There's no indication of how Dean knows how or where to find Mary and John at the end.

  • Trivia: Dean's date of birth is 24th January 1979.
