The Convict's Piano - S2-E11

Revealing mistake: In the close-up of Frost's hand while the doctor is stitching up his wound, you can see the delineated edges of the latex make-up patch used to simulate the injury. (00:12:30)

The Card - S2-E13

Revealing mistake: When Linda pulls The Card out of her wallet in close-up, it's twice the length of an average credit card so that we can read the name printed on it. In the next shot, though, it shrinks back to standard size. (00:17:05)

Revealing mistake: The Styrofoam head Gus tears in half shows it has been pre-cut, making it easier for him to rip in half.
