Continuity mistake: Laura meets a guy named Ted supposedly for the first time. He is selling candy bars around the neighborhood and happens to knock on the Winslow family's door. Laura goes out on a date with him. However, Ted and Laura have already had several interactions, and have already dated and broken up in previous episodes in season 4.
Continuity mistake: Towards the beginning, Carl enters with a new video camera and we see a regular view of the scene mixed with POV shots from the camera as Carl narrates. When he's standing at the door with his bag, in the POV shots from the camera you can see that the door is open, but in the wide shots, it is closed.
