Continuity: When Sam and Dean enter the Shoemaker home, a woman leaning against a wall holding a coffee cup starts to follow them down the hall. When the shot changes, the woman is back against the wall, talking to someone who wasn't there in the previous shot.

Continuity: When Sam and Dean are tied up in the sewer, Dean gets out of the ropes holding him and the camera changes to Sam, but in the background you can see Dean with the ropes still around his arms & upper body.

Continuity: 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.

Visible crew/equipment: In the scene where Sam tells the little to girl to take her brother outside. The little girl runs out with her brother and Dean asks the little girl where Sam is, Dean runs to the Impala and grabs a shotgun. When Dean is running to the house, he runs on the lawn and you can see the shadow of the camera man running with Dean at the bottom of the screen.

Continuity: When Dean reads about the Roosevelt Asylum in his dad's journal, there is a picture of a Wendigo on the opposite page of the newspaper clipping but in a different scene, Dean checks the article again for information on the South Wing in the Asylum but this time on the opposite page of the newspaper clipping, there is no picture.

Continuity: Near the end of the episode when Dean is being chased by the possessed truck, Sam tells him to take a left. After he's made the left, Sam tells him to go exactly 7/10ths of a mile and stop. Dean looks at his gage and it reads 70098.3. Dean looks up, then back at it: it changes to 70098.5, but the next time he looks down it says 70100.6 and when he stops it says 70101.0, meaning he's gone 2 miles too far. (Probably meaning it took two shots to get the scene right but they messed up on the gage.)
