Post Traumatic Slide Syndrome - S2-E8
Continuity mistake: When Wade enters the recording studio to see Rembrandt, we can see him reflected in the window removing his headphones and handing them to an assistant. The camera angle changes and he removes the headphones (again) & puts them down on a stool.
Continuity mistake: Quinn finds Natalie and goes over to where she is drinking and conversing with a man seated at a table. Quinn goes over, and in the next shot, she is alone at the table.
Continuity mistake: When the car pulls into the computer store, there is only one occupant. However, Rembrandt, Quinn and Wade are all inside. (Incidentally, the reason this mistake occurred is that the shot of the car pulling into the parking spot was recycled from the Pilot episode).
