Continuity: As Chloe leaves Clark calls out her name. In the shot from Chloe's side of the room, Clark is holding the pitchfork horizontally low in front of him. The shot switches, as Chloe finishes her turn, and now Clark is holding the pitchfork with his arm bent so that the pitchfork is no longer low in front of his waist.

Continuity: Near the end when Clark and Chloe are talking in his barn, Clark calls to her as she walks away. His arm snaps from straight from the front to bent from behind.

Revealing: When the gas pipe explodes at the beginning before the credits, the camera goes to an aerial view. You can see that the explosion started from behind the gas pipes.
