This is the episode where Leo and Piper tried to get married during the eclipse. Also the one with the guy who changes into an owl. In the very beginning if the episode, Piper drives up to the house. She gets out of her car and is almost hit by another car going down the street. Well they change the camera views and in one view the car door behind her is shut. Then they switch views and show her slamming the car door. Last time I checked car doors didn't open themselves.
