Corrected entry: In the scene when John is talking to Mr. D in the diner, Mr. D tells John to "say hello to your old man for me." It is later revealed in season 8 that John's father left them when he was young. This is a mistake, unless Mr. D is referring to John's grandfather (unlikely). (00:04:40)
Corrected entry: In the scene where Sam and Dean are getting coffee [right after Dean puts the itching powder in Sam's underwear], as the boy behind the counter hands Dean the coffee cup you can hear him say, "Here you go, Jensen. Jensen is actually the first name of the actor who plays Dean, 'Jensen Ackles'.
Corrected entry: At The End of the episode, Dean and Sam pull up to the house to say goodbye. The moving truck has its back end facing the right, toward the front of the brothers' Impala. However, when they are driving away, heading straight without turning around, the moving truck is now facing in the opposite direction.
Corrected entry: Sam switches bodies with a 17 year old kid named Gary. NOTE: Sam has always been taller than Dean. When Dean and Gary (in Sam's body) are walking and talking, Dean looks down to talk to Gary. Since Gary is supposed to be in Sam's body, Dean should be looking slightly up. Also, when Dean finally listens to his voice-mail and hears Sam (in Gary's body) we hear Sam's voice. We should have been hearing Gary's.
Corrected entry: Gabriel is referred to as an archangel. While that is a common misconception, and while Gabriel was one of the serafs, he was not the archangel. By definition, there can only be one archangel, and according to the Bible, that's Michael. You'd think Gabriel would be aware of that.
Corrected entry: Season 4, Episode 15: "Death Takes a Holiday": Sam and Dean Astro-Project out of their bodies so that they can see and save a Reaper. They are out of their bodies, walking down a street as ghosts, but their breath is visible due to the cold weather outside. Ghosts have no body to generate warm or hot breath.
